An Approach to Overcome the Limitations of Surveillance of Asbestos Related Diseases in Low- and Middle-Income Countries: What We Learned from the Sibaté Study in Colombia.

Introduction: The asbestos industry began its operations in Colombia in 1942 with the establishment of an asbestos-cement facility in Sibaté, located in the Department of Cundinamarca. Despite extensive asbestos use and production in Colombia, the country lacks a reliable epidemiological surveillance system to monitor the health effects of asbestos exposure. The Colombian health information system, known as SISPRO, did not report mesothelioma cases diagnosed in the municipality, posing a significant challenge in understanding the health impacts of asbestos exposure on the population of Sibaté. Methods: To address this issue, an active surveillance strategy was implemented in Sibaté. This strategy involved conducting door-to-door health and socioeconomic structured interviews to identify Asbestos-Related Diseases (ARDs). Validation strategies included a thorough review of medical records by a panel of physicians, and the findings were communicated to local, regional, and national authorities, as well as the general population. Results: The active surveillance strategy successfully identified a mesothelioma cluster in Sibaté, revealing the inadequacy of the existing health information system in monitoring asbestos-related diseases. The discovery of this cluster underscores the critical importance of implementing active surveillance strategies in Colombia, where governmental institutions and resources are often limited. Conclusion: The findings of this study emphasize the urgent need for Colombia to establish a reliable epidemiological surveillance system for asbestos-related diseases (ARDs). Active surveillance strategies can play a crucial role in identifying mesothelioma clusters and enhancing our understanding of the health effects of asbestos exposure in low- and middle-income countries.

Sustainability of Italian seaports located near contaminated sites: results of an exploratory analysis.

INTRODUCTION: Ports are strategic areas of economic importance, but they are also very critical contexts. Many Italian ports are included in contaminated sites of concern for remediation, with the presence of pressure factors that overload the burden capacity of local ecosystems and communities. AIM: The aim of this study is to characterize Italian seaport areas through a general theoretical path on the theme of ports-sustainability-local communities, identifying the ports located in municipalities included in contaminated sites studied by the SENTIERI Project (Epidemiological Study of Residents in Italian Contaminated Sites). Many of the selected ports, are being part of complex industrial areas, where, in addition to the port area, there are other sources of environmental contamination potentially harmful to health. RESULTS: Excesses risk were observed for mesothelioma and for respiratory diseases, pathologies for which there is epidemiological evidence of an excess of risk associated with residence in port areas. DISCUSSION: The strong environmental pressures that characterize these areas make it necessary to adopt adequate environmental and health protection measures.

[SENTIERI - Epidemiological Study of Residents in National Priority Contaminated Sites. Sixth Report]. / SENTIERI - Studio epidemiologico nazionale dei territori e degli insediamenti esposti a rischio da inquinamento. Sesto Rapporto.

INTRODUCTION ADN OBJECTIVES: The Sixth Report presents the results of the "SENTIERI Project: implementation of the permanent epidemiological surveillance system of populations residing in Italian Sites of Remediation Interest", promoted and financed by the Italian Ministry of Health (Centre for Disease Control and Prevention - CCM Project 2018). The aim of this study is to update the mortality and hospitalization analyses concerning the 6,227,531 inhabitants (10.4% of the Italian population) residing in 46 contaminated sites (39 of national interest and 7 of regional interest). The sites include 316 municipalities distributed as follows: 15 in the North-East (20.3% of the investigated population); 104 in the North-West (12% of the investigated population), 32 in the Centre (12.6% of the investigated population), 165 in the South and Islands (55.5% of the investigated population). Analyses were carried out on the paediatric-adolescent (1,128,396 residents) and youth (665,284 residents) population, and a study on congenital anomalies (CA) was carried out at sites covered by congenital malformation registers. Accompanying the epidemiological assessments, site-specific socioeconomic conditions were examined and an overall estimate of excess risk for populations residing at contaminated sites was drawn up. By means of a systematic review of the scientific literature, the epidemiological evidence on causal links between sources of environmental exposure and health effects was updated to identify pathologies of a priori interest. METHODOLOGY: In the 46 sites included in the SENTIERI Project, mortality (time window: 2013-2017) and hospital admissions (time window: 2014-2018) of the general population of all ages, divided by gender, and of the paediatric-adolescent (0-1 year, 0-14 years, 0-19 years), youth (20-29 years), and overall (0-29 years) age groups, divided by gender, were analysed. In 21 sites, CA diagnosed within the first year of life were studied. Standardised mortality ratios (SMR) and hospitalization ratios (SHR) were calculated with reference to the rates in the regions to which the sites belong. The reference population was calculated net of residents in the sites. CA were studied by calculating the prevalence per 10,000 births and the ratio, multiplied by 100, between the cases observed at the site and those expected on the basis of the prevalences observed in the reference area (region or sub-regional area of belonging, according to the geographical coverage of the registry). The socioeconomic condition studied in the 46 sites is based on the convergence of three deprivation indicators with respect to the reference region: deprivation index at municipal level, deprivation index at census section level, premature mortality indicator (age range 30-69 years) for chronic non-communicable diseases. For the estimation of excess risk for the entire study population, meta-analysis of the mortality and hospitalization risk estimates for each site was carried out and the number of excess deaths estimated for the sites as a whole. The epidemiological evidence was updated through a systematic literature review (January 2009-May 2020), following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The search was carried out on the search engines MEDLINE, EMBASE and Web of Science; the quality of the studies included in the review was assessed using the AMSTAR 2 checklist for systematic reviews and the NewCastle-Ottawa Scale for observational studies in the case of cohort and case-control studies and a modified version thereof for ecological and cross-sectional studies. The update was based on the selection of 14 systematic reviews, 15 primary studies, 6 monographs/reports from international scientific organisations on health effects due to the presence of environmental exposure sources. RESULTS: Mortality. The a priori causes of interest that occur most frequently in excess are, in descending order: malignant lung cancer, malignant mesothelioma of the pleura, malignant bladder cancer, respiratory diseases, non-Hodgkin lymphomas, malignant liver cancer, all malignant tumours, malignant colorectal cancer, malignant stomach cancer, total mesotheliomas, malignant breast cancer, and asbestosis. Hospitalization. The a priori causes of interest that occur most frequently in excess are represented in descending order by: respiratory diseases, malignant lung cancer, malignant tumours of the pleura, malignant bladder cancer, malignant breast cancer, malignant liver cancer, asthma, malignant colorectal cancer, all malignant tumours, malignant stomach cancer, non-Hodgkin's lymphomas, acute respiratory diseases, leukaemias. The differences observed between mortality and hospitalization can be attributed to the intrinsic characteristics of the diseases (higher or lower lethality, gender differences in incidence), lifestyles, and occupational phenomena. Age classes. Excesses of general mortality were observed in the first year of life at the Manfredonia, Basso Bacino Fiume Chienti, Litorale Domizio Flegreo and Agro Aversano sites; in the 0-1 year and 0-19 year age groups at Casale Monferrato; in the paediatric age group at Serravalle Scrivia and at the Trento Nord site; in the 0-19 year age group at Sassuolo Scandiano; in the young age group (0-29 years) at the two municipalities of Cerchiara and Cassano (Crotone-Cassano-Cerchiara site). With regard to hospitalization due to natural causes, risk excesses in both genders are found in the first year of life in 35% of the sites (Porto Torres industrial areas, Bari-Fibronit, Basso bacino fiume Chienti, Bolzano, Crotone-Cassano-Cerchiara, Cerro al Lambro, Bologna ETR large repair workshop, Gela, Manfredonia, Massa Carrara, Pioltello Rodano, Pitelli, Priolo, Sesto San Giovanni, Trento Nord, and Trieste). These same sites, with the addition of Casale Monferrato, Cengio e Saliceto, Serravalle Scrivia, and Sulcis-Iglesiente-Guspinese (total: 43% of sites), show excesses for all natural causes, in both genders, even in the paediatric-adolescent age group (0-19 years). Among young adults (20-29 years), the analyses show excesses of hospitalization for all natural causes in both genders in the Bolzano, Crotone-Cassano-Cerchiara, Gela, Manfredonia, Pitelli, Priolo, and Sulcis-Iglesiente-Guspinese sites. Among young women only, excesses for all natural causes are also found in Brescia Caffaro, Brindisi, Broni, Casale Monferrato, Crotone-Cassano-Cerchiara, Falconara Marittima, Fidenza, and Massa Carrara. Congenital anomalies. In the 21 sites investigated for CA, 10,126 cases of CA, validated by participating registers, were analysed out of 304,620 resident births. Genital CA is the subgroup for which the greatest number of excesses was observed (in 6 out of 21 sites). The available evidence does not allow a causal link to be established between the excesses observed for specific subgroups of ACs and exposure to industrial sources, but the results suggest further action. The interpretation of the results appears, in fact, particularly complex as the scientific literature on the association between exposure to industrial sources and AC is very limited. Socioeconomic status. The sites in which the indicators converge to show the presence of fragility are: Litorale Vesuviano area, Val Basento industrial areas, Basso Bacino fiume Chienti, Biancavilla, Crotone-Cassano-Cerchiara, Litorale Domizio Flegreo and Agro Aversano, Livorno, Massa Carrara, Trieste. Global impact. Over the period 2013-2017, an estimated 8,342 excess deaths (CI90% 1,875-14,809) or approximately 1,668 excess cases/year, 4,353 excess deaths among males (CI90% 334-8,372) and 3,989 among females (CI90% -1,122;9,101). The pooled excess risk of general mortality is 2% in both genders (pooled SMR 1.02; CI90% 1.00-1.04). The proportion of excess deaths to total observed deaths is almost constant over time, rising from 2.5% in 1995-2002 to 2.6% in 2013-2017. The number of deaths in absolute value is also very similar between the periods analysed. Deaths from all malignant tumours contribute the most by accounting for 56% of the observed excesses, the excess risk of mortality from malignant tumours across all sites, compared to the reference populations, is 4% in the male population (pooled SMR 1.04; CI90% 1.01-1.06) and 3% among the female population (pooled SMR 1.03; CI90% 1.01-1.05). Hospitalization (2014-2018) in the 46 sites as a whole was in excess of 3% for all causes, in both genders, for all major disease groups (males: SHR pooled 1.03; CI90% 1.01-1.04 - females: SHR pooled 1.03; CI90% 1.01-1.05). The results for the pooled estimates at the 46 sites on the general population, both with regard to mortality and hospitalization, are consistent in indicating excess risk in both genders for all the diseases considered and, in particular, for all malignancies. A total of 1,409 paediatric-adolescent deaths and 999 young adult deaths were observed, and the pooled analysis of mortality across the 46 sites showed no critical issues, with pooled estimates for all causes, perinatal morbid conditions and all malignancies falling short of expectations. The analysis of hospitalizations, on the other hand, showed an excess risk of 8% (males: SHR pooled 1.08; CI90% 1.03-1.13 - females: SHR pooled 1.08; CI90% 1.03-1.14) for all causes in the first year of life, and in paediatric-adolescent and juvenile age of 3-4% among males (age 0-19 years: SHR pooled 1.04; CI90% 1.02-1.06 - age 20-29 years: SHR pooled 1.03; CI90% 1.00-1.05) and 5% among females (in both age groups; SHR pooled 1.05; CI90% 1.02-1.08). The pooled analysis of mortality for the a priori identified diseases reported excesses for specific diseases in the group of sites with sources of exposure associated with them. Mortality from total mesotheliomas is three times higher at sites with asbestos present (males:pooled SMR 3.02; CI90% 2.18-3.87 - females: pooled SMR 3.61; CI90% 2.33-4.88) and that from pleural mesotheliomas more than two times higher at the group of sites with asbestos and port areas (males: pooled SMR 2.47; CI90% 1.94-3.00 - females: pooled SMR 2.43; CI90% 1.67-3.19). Lung cancer was in excess by 6% among males (pooled SMR 1.06; CI90% 1.03-1.10) and 7% among females (pooled SMR 1.07; CI90% 1.00-1.13). In addition, there are excess mortalities for colorectal cancer at sites with chemical plants, by 4 % among males (SMR pooled 1.04; CI90% 1.01-1.08) and 3 % among females (SMR pooled 1.03; CI90% 1.00-1.07) and for bladder cancer among the male population of sites with landfills (+6 %: SMR pooled 1.06; CI90% 1.02-1.11). Among the diseases of a priori interest, stomach and soft tissue cancers are at fault as a cause of death among all the sites considered. LITERATURE REVIEW: The update of the epidemiological evidence underlying the Sixth SENTIERI Report has highlighted in the general population a possible association, previously undiscovered, between certain diseases and residence near petrochemical and steel plants, landfills, coal mines and asbestos sources. CONCLUSIONS AND PERSPECTIVES: Despite the fact that this is an ecological study, and the excesses of pathologies with multifactorial aetiology can never be mechanically attributed solely to the environmental pressure factors that exist or existed in the areas studied, the ability to identify the excesses found in the contaminated sites investigated by the SENTIERI Project confirms the validity of this method of assessing the site-specific health profile, based on the use of epidemiological evidence to identify pathologies of interest a priori. In interpreting the data and lending robustness to what has been observed, comparison with the results obtained in previous Reports is essential. The global estimates give an overall picture that shows excess mortality and hospitalization in these populations compared to the rest of the population, and show how, for specific pathologies, comparable effects are produced at sites with similar contamination characteristics. The themes developed in the in-depth chapters broaden the vision and understanding of the complex interactions between environment and health, describe the possibilities offered by new ways of communicating the results, and confirm the modernity of a Project that began way back in 2006, and that could be grafted onto the objectives of the National Recovery and Resilience Plan within the framework of the Operational Programme Health, Environment, Biodiversity and Climate.

The Italian Experience in the Development of Mesothelioma Registries: A Pathway for Other Countries to Address the Negative Legacy of Asbestos.

Asbestos (all forms, including chrysotile, crocidolite, amosite, tremolite, actinolite, and anthophyllite) is carcinogenic to humans and causally associated with mesothelioma and cancer of the lung, larynx, and ovary. It is one of the carcinogens most diffuse in the world, in workplaces, but also in the environment and is responsible for a very high global cancer burden. A large number of countries, mostly with high-income economies, has banned the use of asbestos which, however, is still widespread in low- and middle-income countries. It remains, thus, one of the most common occupational and environmental carcinogens worldwide. Italy issued an asbestos ban in 1992, following the dramatic observation of a large increase in mortality from mesothelioma and other asbestos-related diseases in exposed workers and also in subjects with non-occupational exposure. A mesothelioma registry was also organized and still monitors the occurrence of mesothelioma cases, conducting a case-by-case evaluation of asbestos exposure. In this report, we describe two Italian communities, Casale Monferrato and Broni, that faced an epidemic of mesothelioma resulting from the production of asbestos cement and the diffuse environmental exposure; we present the activity and results of the Italian mesothelioma registry (ReNaM), describe the risk-communication activities at the local and national level with a focus on international cooperation and also describe the interaction between mesothelioma registration and medical services specialized in mesothelioma diagnosis and treatment in an area at high risk of mesothelioma. Finally, we assess the potential application of the solutions and methods already developed in Italy in a city in Colombia with high mesothelioma incidence associated with the production of asbestos-cement materials and the presence of diffuse environmental asbestos pollution.

Where are the landfilled zones? Use of historical geographic information and local spatial knowledge to determine the location of underground asbestos contamination in Sibaté (Colombia).

INTRODUCTION: Sibaté is a municipality located in the central region of Colombia, where the first asbestos-cement facility of the country has been in operation since 1942. Both a malignant pleural mesothelioma cluster and landfilled zones with the presence of an underground friable asbestos layer have been identified in Sibaté. There is still limited knowledge regarding the history of the construction of landfilled zones, and what kinds of materials were deposited. The current study aims to improve our understanding of the history and characteristics of the landfilled zones present in Sibaté. METHODS: Two participatory workshops with inhabitants of Sibaté were conducted to determine when the landfilled zones were built and their location. Information collected in participatory workshops was crossed with both topographic maps and aerial photographs, giving special attention to zones within the urban area of the municipality that in the past were inundated with water from El Muña Reservoir. An opportunistic soil sampling campaign was conducted in suspected landfilled zones that had not been previously sampled, during the replacement of pipelines of the drainage system ordered by the municipality. RESULTS: The analysis of historical topographic maps, combined with the interpretation of aerial photographs, confirmed the disposal of residues in areas that were previously inundated with water from El Muña Reservoir, creating landfilled zones in the urban area of Sibaté. On top of these landfilled zones, a football stadium and a football field with an athletic track were built. The location of landfilled zones identified using geographic analysis was similar to the location identified analyzing maps constructed by inhabitants of Sibaté in participatory workshops. The four soil samples collected during an opportunistic sampling campaign confirmed the presence in new locations of the underground friable asbestos layer discovered in previous studies. DISCUSSION: Based on the extension of the landfilled zones, the presence of friable asbestos in these areas, and the close proximity to a school and residential dwellings, there could have been major dispersion events of asbestos fibers in the urban area of Sibaté during the disposal of residue materials and the construction of the landfilled zones. Thus, important asbestos exposures may have occurred among residents of Sibaté, which is aggravated by the fact that during those years, more than 50% of the population of Sibaté was 25 years old or younger. Although the results of the current study improved our understanding of the processes and chronology associated with the landfilled zones, the uncertainty regarding their exact location remains significant. It is important to continue investigating the adverse health effects resulting from this potential asbestos exposure source.

Epidemiological research as a driver of prevention: the Sibaté study. Commentary.

Although asbestos exposure and risks can be prevented, only five countries in Latin America have banned asbestos, including Colombia. Beginning in 2011, a collaboration between the Istituto Superiore di Sanità in Italy and Universidad de los Andes in Colombia was established, bringing together relevant expertise aiming to improve our understanding of the asbestos problem. An important result of this collaboration was a recently published study conducted in Sibaté, Colombia, a municipality where an asbestos-cement facility has operated since 1942. The evidence collected suggests the presence of a mesothelioma cluster in Sibaté. Landfilled zones with an underground layer of friable asbestos were also discovered in the urban area of the municipality. The importance of this type of collaboration can go beyond understanding the impact of asbestos at the local level, which is crucial, and may also contribute in solving unanswered questions of the problem in countries that banned asbestos decades ago.

SARS-CoV-2 and Asbestos Exposure: Can Our Experience With Mesothelioma Patients Help Us Understand the Psychological Consequences of COVID-19 and Develop Interventions?

Since its emergence, the novel coronavirus disease of 2019 (COVID-19) has had enormous physical, social, and psychological impacts worldwide. The aim of this article was to identify elements of our knowledge on asbestos exposure and malignant mesothelioma (MM) that can provide insight into the psychological impact of the COVID-19 pandemic and be used to develop adequate interventions. Although the etiology of Covid-19 and MM differs, their psychological impacts have common characteristics: in both diseases, there is a feeling of being exposed through aerial contagion to an "invisible killer" without boundaries that can strike even the strongest individuals. In both cases, affected persons can experience personality dysfunction, anxiety, depression, and posttraumatic symptoms; helplessness, hopelessness, and projection of destructive thoughts onto external forces often emerge, while defense mechanisms such as denial, splitting, repression, and reduced emotional expression are used by individuals to contain their overwhelming anxieties. We believe that in both diseases, an integrated multidimensional intervention offered by hospitals and other public health services is the most effective approach to alleviating patients' and caregivers' psychological distress. In particular, we emphasize that in the context of both MM and COVID-19, Brief Psychoanalytic Group therapy can help patients and caregivers attribute meaning to the significant changes in their lives related to the experience of the disease and identify adaptive strategies and more realistic relational modalities to deal with what has happened to them. We also highlight the importance of developing a surveillance system that includes individual anamnestic evaluation of occupational risk factors for COVID-19 disease.

Environmental Health Education for Asbestos-Contaminated Communities in Italy: The Casale Monferrato Case Study.

BACKGROUND: Environmental health education contributes towards increasing awareness of communities to prevent exposure to hazardous substances. Casale Monferrato, the operating site for the Eternit asbestos-cement factory from 1907 to 1986, is a prioritized asbestos-contaminated site for remediation in Italy. The area is prone to severe asbestos-related diseases. About 50 cases of mesothelioma are diagnosed in Casale Monferrato annually; mesothelioma has been shown to be caused by occupational, environmental and domestic asbestos exposure. OBJECTIVES: The goal of this paper is to analyze the Casale Monferrato case study in terms of youth engagement in environmental health education initiatives on asbestos risk and health impact. The paper aims at underlining the lessons learned in order to share the success of this initiative with other communities living in asbestos-contaminated sites in different countries. METHODS: Peer education methodology has been used through the Asbestos Classroom to involve teachers, students and other local stakeholders in training activities, in selection of the contents for educational materials and interactive tools, as well as in choosing the presentation process for the aforementioned knowledge sharing instruments. FINDINGS: From November 2014 to June 2018, 185 high school students and teachers were trained through the Asbestos Classroom. Through December 2018, they trained 3,241 classroom visitors. The Classroom relies on an inclusive participative process in which young people play a key role in the network of relationships within their community. CONCLUSIONS: The paper corroborates the importance of engaging the educational system in communication efforts aimed at fostering collective awareness on environmental risk and health-related impacts for communities living in industrially contaminated sites. Considering the global dimension of the asbestos contamination and disease burden, this experience might be of relevance both in countries that banned asbestos and in those where asbestos is not yet prohibited.

An asbestos contaminated town in the vicinity of an asbestos-cement facility: The case study of Sibaté, Colombia.

INTRODUCTION: The asbestos industry began operations in Colombia in 1942, with an asbestos-cement facility located in the municipality of Sibaté. In recent years residents from Sibaté have been complaining about what they consider is an unusually large number of people diagnosed with asbestos-related diseases in the town. A study to analyze the situation of Sibaté started in 2015, to verify if the number of asbestos related diseases being diagnosed were higher than expected, and to identify potential asbestos exposure sources in the town. METHODS: A health and socioeconomic survey was implemented door-to-door to identify potential asbestos-related diseases. Several self-reported mesothelioma cases were identified, and for confirmation purposes, copies of the medical record with the histopathology report were obtained. A panel of six physicians analyzed the medical records. Information of validated cases was used to estimate the male and female age-adjusted incidence rate for Sibaté. Based on reports of the existence of potential asbestos-contaminated landfills, topographic maps, a digital elevation model, and current satellite images were crossed using a geographic information system to identify potential landfilled areas, and soils samples were collected in some of these areas. RESULTS: A total of 355 surveys were completed, and 29 self-reported mesothelioma cases were identified. Twenty-five of these cases have been persons who had lived at some moment of their lives in Sibaté. It was possible to obtain copies of the medical diagnosis for 17 cases. Of these, the panel of physicians classified 15 cases as certain pleural mesothelioma, one as probable, and one as not mesothelioma. Based on this information, the estimated age-adjusted incidence rate of mesothelioma in Sibaté was 3.1 × 105 persons-year for males and 1.6 × 105 persons-year for females. These rates are high in comparison to those reported in other cities, regions, and countries of the world. Using geographic information systems, landfilled zones in the urban area of Sibaté were identified, on top of which a school and different sports facilities were built. The analysis of four soil samples collected in landfilled zones, confirmed the existence of an underground layer of friable and non-friable asbestos. CONCLUSION: The collected evidence suggests the presence of a malignant pleural mesothelioma cluster in Sibaté.

Communication and health education in communities experiencing asbestos risk and health impacts in Italy.

INTRODUCTION: Numerous municipalities in Italy currently experience asbestos health impact, in particular excesses of pleural mesothelioma incidence and mortality. This paper presents an integrated analysis of epidemiological studies and communication actions in affected municipalities to highlight how communication has been implemented depending on health impact evidence and involvement of local stakeholders. METHODOLOGY: Four case studies are identified concerning industrial and natural sources of asbestos exposure having different diseases burden. This integrated analysis benefited from multidisciplinary skills. DISCUSSION: Evidence of different stakeholders engagement is presented to emphasize their role in the communication process. Similarities and differences among case studies allowed us to identify lessons-learned to be transferred in other asbestos contaminated sites. CONCLUSIONS: The adoption of communication strategies and practices, since the very early evidence of asbestos health impact, represents a relevant contribution for epidemiological and health surveillance, particularly for those communities where asbestos health impact has only been recently reported.

Prevention of Asbestos Exposure in Latin America within a Global Public Health Perspective.

BACKGROUND: Asbestos consumption in Latin America (LA) amounts to 10% of yearly global production. Little is known about the impact of asbestos exposure in the region. OBJECTIVE: To discuss scientific and socio-economic issues and conflicts of interest and to summarize epidemiological data of asbestos health effects in LA. DISCUSSION: Recent data on chrysotile strengthened the evidence of its carcinogenicity and showed an excessive risk of lung cancer at cumulative exposure levels as low as 1.5 fibre-years/ml. Technology for substitution is available for all asbestos-containing products and ceasing asbestos production and manufacturing will not result in unemployment and loss of income, except for the mining industry. The flawed arguments used by the industry to maintain its market, both to the public and in courtrooms, strongly relies on the lack of local evidence of the ill effects and on the invisibility of asbestos-related diseases in LA, due to the limited number of studies and the exposed workers' difficulty accessing health services. The few epidemiological studies available show clear evidence of clusters of mesothelioma in municipalities with a history of asbestos consumption and a forecasted rise in its incidence in Argentina and Brazil for the next decade. In Brazil, non-governmental organizations of asbestos workers were pivotal to counterbalance misinformation and inequities, ending recently in a Supreme Court decision backing an asbestos ban. In parallel, continuous efforts should be made to stimulate the growth of competent and ethical researchers to convey adequate information to the scientific community and to the general public.

Asbestos Ban in Italy: A Major Milestone, Not the Final Cut.

Background and history: Italy was the main asbestos producer and one of the greatest consumers in 20th century Europe until the asbestos ban was introduced in 1992. Asbestos exposure affected the population in a wide range of working environments, namely mining and marketing of asbestos, asbestos cement production, shipyards and textile industries. This also determined a widespread environmental asbestos exposure affecting the surrounding communities. Methods: To investigate the drivers and difficulties of the process leading to the asbestos ban and its subsequent implementation, we focused on stakeholder involvement, environmental health policies, capacity building and communication. Results: In the past three decades, stakeholder involvement has been instrumental in advancing the industrial asbestos replacement process, prevention and remediation interventions. Furthermore, involvement also contributed to the integration of environmental and health policies at national, regional and local levels, including capacity building and communication. In a global public health perspective, international scientific cooperation has been established with countries using and producing asbestos. Discussion and Conclusions: Key factors and lessons learnt in Italy from both successful and ineffective asbestos policies are described to support the relevant stakeholders in countries still using asbestos contributing to the termination of its use.

Prevention of Asbestos-Related Disease in Countries Currently Using Asbestos.

More than 40 years of evaluation have consistently confirmed the carcinogenicity of asbestos in all of its forms. This notwithstanding, according to recent figures, the annual world production of asbestos is approximatively 2,000,000 tons. Currently, about 90% of world asbestos comes from four countries: Russia, China, Brazil and Kazakhstan; and the wide use of asbestos worldwide represents a global threat. The purpose of this paper is to present a review of the asbestos health impact and to discuss the role of epidemiological investigations in countries where asbestos is still used. In these contexts, new, "local" studies can stimulate awareness of the size of the problem by public opinion and other stakeholders and provide important information on the circumstances of exposure, as well as local asbestos-related health impacts. This paper suggests an agenda for an international cooperation framework dedicated to foster a public health response to asbestos, including: new epidemiological studies for assessing the health impact of asbestos in specific contexts; socio-cultural and economic analyses for contributing to identifying stakeholders and to address both the local and global implications of asbestos diffusion; public awareness on the health and socio-economic impact of asbestos use and banning.

Environmental health literacy within the Italian Asbestos Project: experience in Italy and Latin American contexts. Commentary.

The adoption of multidisciplinary approaches to foster scientific research in public health and strengthen its impact on society is nowadays unavoidable. Environmental health literacy (EHL) may be defined as the ability to search for, understand, evaluate, and use environmental health information to promote the adoption of informed choices, the reduction of health risks, the improvement of quality of life and the protection of the environment. Both public health and environmental health literacy involve access to and dissemination of scientific information (including research findings), individual and collective decision-making and critical thinking. Specific experiences in environmental health literacy have been developed within the Italian National Asbestos Project (Progetto Amianto) in Latin American countries where the use of asbestos is still permitted, and in Italy where a specific effort in EHL has been dedicated to the risks caused by the presence of fluoro-edenite fibers in the town of Biancavilla (Sicily). Taking into account the different geographical and socio-economic contexts, both public health and environmental health literacy were addressed to a wide range of stakeholders, within and outside the health domain.

Occupational burden of asbestos-related cancer in Argentina, Brazil, Colombia, and Mexico.

BACKGROUND: An estimate at the national level of the occupational cancer burden brought about by the industrial use of asbestos requires detailed routine information on such uses as well as on vital statistics of good quality. A causal association with asbestos exposure has been established for mesothelioma and cancers of the lung, larynx, and ovary. OBJECTIVES: The aim of this study was to provide estimates of the occupational burden of asbestos-related cancer for the Latin American countries that are or have been the highest asbestos consumers in the region: Argentina, Brazil, Colombia, and Mexico. METHODS: The burden of multifactorial cancers has been estimated through the approach suggested for the World Health Organization using the population attributable fraction. The following data were used: Proportion of workforce employed in each economic sector. Proportion of workers exposed to asbestos in each sector. Occupational turnover. Levels of exposure. Proportion of the population in the workforce. Relative risk for each considered disease for 1 or more levels of exposure. Data on the proportion of workers exposed to asbestos in each sector are not available for Latin American countries; therefore, data from the European CAREX database (carcinogen exposure database) were used. FINDINGS: Using mortality data of the World Health Organization Health Statistics database for the year 2009 and applying the estimated values for population attributable fractions, the number of estimated deaths in 5 years for mesothelioma and for lung, larynx, and ovary cancers attributable to occupational asbestos exposures, were respectively 735, 233, 29, and 14 for Argentina; 340, 611, 68, and 43 for Brazil; 255, 97, 14, and 9 for Colombia, and 1075, 219, 18, and 22 for Mexico. CONCLUSIONS: The limitations in compiling the estimates highlight the need for improvement in the quality of asbestos-related environmental and health data. Nevertheless, the figures are already usable to promote a ban on asbestos use.

Asbestos case and its current implications for global health.

Notwithstanding a major body of evidence on the carcinogenicity of all asbestos fibres and a general consensus of the scientific community on the health impact of this agent, asbestos is still produced and used in a large number of countries, thus determining further harm for future generations. Prevention of asbestos-related disease requires international cooperation, transfer of know-how and dissemination of successful procedures in order to contrast asbestos exposure in the frame of a global environmental health approach.

La prevención de las patologías del asbesto: perspectivas operativas de la cooperación italiana con los países de América Latina / Preventing asbestos-related diseases: operative action for Italian cooperation with Latin-American countries

El propósito del presente estudio es el de valorar la tesis de que el impacto a la salud de la exposición a fibras de asbesto presentes en los lugares de trabajo y en el ambiente requiere contramedidas basadas en la evidencia científica y la cooperación internacional. La evidencia científica adquirida a nivel internacional sobre el asbesto, la experiencia pluridecenal madurada en Italia sobre este tema, así como la conciencia de que la adaptación de medidas para combatir los efectos en la salud causados por la exposición a asbesto debe ser verificada considerando la especificidad de los diversos contextos nacionales y locales en América Latina, constituyen la base para la identificación de las cuatro principales directrices de intervención (Promoción del acceso a la documentación sobre el asbesto - Realización de intervenciones para reducir la exposición al asbesto - Vigilancia sanitaria de los sujetos expuestos - Detección del mesotelioma) - que pueden ser desarrolladas en el ámbito de la cooperación técnico-científica entre Italia y los países de América Latina. La integración de las capacidades de los investigadores colombianos e italianos podrá permitir conseguir estos resultados, contribuyendo al proceso de eliminación del asbesto ya en curso en América Latina.

The present paper was aimed at promoting countermeasures based on scientific evidence and international cooperation for evaluating the impact on health caused by exposure to asbestos fibres in the workplace and the environment. Scientific evidence regarding asbestos made available by the international scientific community, decades of experience gained in Italy on this issue and being aware that adopting measures to combat the health effects caused by asbestos exposure should be verified considering the specificity of various national and local contexts in Latin-America form the basis for identifying four main areas for intervention which may be developed in the field of technical and scientific cooperation between Italy and Latin-America countries: promoting access to information about asbestos, interventions for reducing exposure to asbestos, health surveillance of exposed subjects and mesothelioma detection. Integrating Colombian and Italian researchers' abilities may lead to such results being achieved, thereby contributing to banning asbestos, which is already underway in Latin-America.
