ABSTRACT
Objective: To quantify the number of avoidable annual deaths and associated economic benefits from meeting the World Health Organization (WHO) air quality guidelines for ambient concentrations for fine particulate matter (PM2.5) for Member States of the WHO Western Pacific Region. Methods: Using the AirQ+ software, we performed a quantitative health impact assessment comparing country-level PM2.5 concentrations with the 2005 and 2021 air quality guidelines recommended maximum concentrations of 10 and 5 µg/m3, respectively. We obtained PM2.5 data from the WHO Global Health Observatory (latest available year 2016), and population and mortality estimates from the United Nations World Population Prospects database for the latest 5-year period available (2015-2019), which we averaged to 1-year estimates. A risk estimate for all-cause mortality, based on a meta-analysis, was embedded within AirQ+ software. Our economic assessment used World Bank value of a statistical life adjusted to country-specific gross domestic product (latest available year 2014). Findings: Data were complete for 21 of 27 Member States. If these countries achieved the 2021 guidelines for PM2.5, an estimated 3.1 million deaths would be avoided annually, which are 0.4 million more deaths avoided than meeting the 2005 guidelines. China would avoid the most deaths per 100 000 population (303 deaths) and Brunei Darussalam the least (5 deaths). The annual economic benefit per capita ranged from 5781 United States dollars (US$) in Singapore to US$ 143 in Solomon Islands. Conclusion: Implementing effective measures to reduce PM2.5 emissions would save a substantial number of lives and money across the Region.

BACKGROUND: Perfluoroalkylated substances (PFAS) in serum are inversely associated with fetal growth. Small for gestational age (SGA) is a measure based on birth weight and gestational age at birth and represents a good indicator of fetal growth but it has been used only in a small number of studies. We examined the association between PFAS exposure and the risk of severe SGA in a PFAS contaminated area in the Veneto Region (North-East of Italy). METHODS: A retrospective cohort study has been developed including all singleton live births reported in the Veneto Region Birth Registry between 2003 and 2018 to mothers living in the contaminated and in a control area. We estimated the association between mothers' area of residence and severe SGA using crude RR (and 95% CI) and stepwise logistic regression, including all the maternal characteristics. RESULTS: The study included 105,114 singleton live births. The occurence of severe SGA was 3.44% in the contaminated area and 2.67% in the control area. The multivariate analysis confirmed that living in the contaminated area significantly increased the odds of severe SGA (adjusted OR 1.27 (95% C.I. 1.16, 1.39)). CONCLUSIONS: The findings suggest that living in a contaminated area by PFAS plays a role in affecting fetal growth and support the hypothesis that PFAS exposure is a risk factor for SGA. Individual data on exposure are needed to confirm the direct association.

BACKGROUND: human exposure to mixtures of chemicals of toxicological interest, typically found in industrial contaminated sites (ICSs), has been associated with a broad range of different health outcomes. Deprived population groups endure most of the burden of disease and premature death associated to the exposure to those pollutants. Characterising the impacts on health of an ICS is a challenging process. Currently the two main methodological approaches used are Human Health Risk Assessment (HHRA) and Environmental Epidemiological (EE) studies. OBJECTIVES: review existing guidance and scientific evidence for HHRA and EE studies applied to contaminated sites that orientate in selecting the most suitable methodological approach for characterising health impacts in ICSs according to the site characteristics, and the availability of environmental, health and sociodemographic data. RESULTS: HHRA has evolved into a more holistic approach, placing more emphasis in planning, community involvement and adapting the dimension of the assessment to the problem formulation and to the availability of resources. Many different HHRA guidelines for contaminated sites has been published worldwide, and although they share a similar framework, the scientific evidence used for deriving reference values and the variet of policy options can result in a wide variability of health risk estimates. This paper condenses different options with the recommendations to use those tools, default values for environmental and exposure levels and toxicological reference values that most suit to the population and characteristics of the ICSs under evaluation. CONCLUSIONS: the suitability to use one or another approach to assess the impact of ICSs on health depends on the availability of data, cost-benefit aspects and the kind of problem that needs to be answered. Risk assessment based on toxicological data can be very rapid and cheap, providing direct information when the intervention to protect the health of population is urgent and no suitable dose-response functions are available from epidemiological studies. Conducting EE studies provide a deeper insight into the problem of the exposure to industrial pollutants that do not require extrapolation from data obtained from toxicological studies or other population, addressing the community concern's more directly. Complementing the results obtained from different approaches, including those from public health surveillance systems, might provide an efficient and complete response to the impact of ICSs.

BACKGROUND: industrially contaminated sites (ICSs) have been recognised as a major public health concern since they involve exposure to multiple environmental stressors, normally distributed unevenly within population. The COST Action on Industrially Contaminated Sites and Health Network (ICSHNet) comprises a European network of experts and institutions to clarify needs and priorities for better characterising the impact on environment and health of ICS. OBJECTIVES: evaluate the availability of information and studies concerning selected ICSs in participating Countries within the ICSHNet, with particular consideration on the accessibility to environmental, health and demographic data, and research and assessment tools. METHODS: to evaluate the availability of data, an Action Questionnaire (AQ) was developed based on previous questionnaires used in different European projects and on expert consultation. The AQ, with 84 items organised in eight sections, was adapted to an on-line version using the software LimeSurvey. The survey was sent to 47 participants within the ICSHNet, to report over a list of 99 ICSs previously identified. RESULTS: information was gathered from 81 sites out of the initially selected 99, reported by 45 participants from 27 Countries (82% of Countries in the ICSHNet). The predominant polluting activities were waste disposal (46%) and chemical industries (37%), affecting all environmental media, but more extensively surface and groundwater (70%) and soil (68%). Main categories of contaminants affecting different media were heavy metals and chlorinated hydrocarbons, but also BTEX (benzene, toluene, ethylbenzene, and xylene) and ambient air pollutants (e.g., particulate matter, SOx). Human health risk assessment was the most prevalent methodological approach for characterising impacts on health (32%), followed by epidemiological studies (26%), and health impact assessment (12%). The low reporting, both referring to data availability or methodologies, could be due to absence of data, or to the fact that the reporting person (many of them from the public health sector) did not know how to reach the environmental information. CONCLUSIONS: survey findings suggest that improving the collection and access to specific environmental, health and demographic data related to ICSs is crucial to meet the methodological requirement to better analyse the health impact of ICSs.

The final meeting of the EXPOsOMICS project "Final Policy Workshop and Stakeholder Consultation" took place 28-29 March 2017 to present the main results of the project and discuss their implications both for future research and for regulatory and policy activities. This paper summarizes presentations and discussions at the meeting related with the main results and advances in exposome research achieved through the EXPOsOMICS project; on other parallel research initiatives on the study of the exposome in Europe and in the United States and their complementarity to EXPOsOMICS; lessons learned from these early studies on the exposome and how they may shape the future of research on environmental exposure assessment; and finally the broader implications of exposome research for risk assessment and policy development on environmental exposures. The main results of EXPOsOMICS in relation to studies of the external exposome and internal exposome in relation to both air pollution and water contaminants were presented as well as new technologies for environmental health research (adductomics) and advances in statistical methods. Although exposome research strengthens the scientific basis for policy development, there is a need in terms of showing added value for public health to: improve communication of research results to non-scientific audiences; target research to the broader landscape of societal challenges; and draw applicable conclusions. Priorities for future work include the development and standardization of methodologies and technologies for assessing the external and internal exposome, improved data sharing and integration, and the demonstration of the added value of exposome science over conventional approaches in answering priority policy questions.

OBJECTIVES: this paper is based upon work from COST Action ICSHNet. To develop and apply recently proposed methods for assessing the health impact of pollution from contaminated sites and apply them to the case of landfills using available large European datasets. METHODS: standard methods for health impact assessment and burden of disease were applied using the available evidence on the health effects of living near a landfill. Geo-referenced data on landfills from the European Pollutant and Transfer Register (E-PRTR) were combined with population density data (European Environment Agency dataset) and disease frequency data from European health for all database (HfA); uncertainty was assessed via simulation methods. Countries covered by the European Environment Agency's E-PRTR registry on contaminated sites were considered (European Union Member States plus four additional European Countries) for the period 2007-2014. Four outcomes, for which suggestive evidence is available, were included: - low birth weight; - congenital anomalies; - respiratory disease; - annoyance from odour. Firstly, they were analysed separately, in terms of excess number of cases, and then combined into disability-adjusted life years (DALYs). RESULTS: 1,544 landfill sites were considered. 29.3 million people (6% of the total population) live within 4 km from one or more of these sites. The number of yearly attributable cases associated with low birth weight, congenital anomalies, respiratory diseases, and annoyance from odour were estimated, respectively, at 1,239, 70, 33,039, and 1,582,624. Associated DALYs were 10,192, 958, 2,688, and 47,505, respectively; 61,325 in total. CONCLUSIONS: estimates indicate a sizable health impact, largest for annoyance from odour, given the high frequency of the outcome and in spite of its lesser severity compared to the other ones. Application of the methodology is relatively straightforward, once the main assumption of causality is made. The present work offers a first approximation of the impact on health of waste landfills in Europe and can be further applied to other contaminated sites.

BACKGROUND: Climate change is a global threat to health and wellbeing. Here we provide findings of an international research project investigating the health and wellbeing impacts of policies to reduce greenhouse gas emissions in urban environments. METHODS: Five European and two Chinese city authorities and partner academic organisations formed the project consortium. The methodology involved modelling the impact of adopted urban climate-change mitigation transport, buildings and energy policy scenarios, usually for the year 2020 and comparing them with business as usual (BAU) scenarios (where policies had not been adopted). Carbon dioxide emissions, health impacting exposures (air pollution, noise and physical activity), health (cardiovascular, respiratory, cancer and leukaemia) and wellbeing (including noise related wellbeing, overall wellbeing, economic wellbeing and inequalities) were modelled. The scenarios were developed from corresponding known levels in 2010 and pre-existing exposure response functions. Additionally there were literature reviews, three longitudinal observational studies and two cross sectional surveys. RESULTS: There are four key findings. Firstly introduction of electric cars may confer some small health benefits but it would be unwise for a city to invest in electric vehicles unless their power generation fuel mix generates fewer emissions than petrol and diesel. Second, adopting policies to reduce private car use may have benefits for carbon dioxide reduction and positive health impacts through reduced noise and increased physical activity. Third, the benefits of carbon dioxide reduction from increasing housing efficiency are likely to be minor and co-benefits for health and wellbeing are dependent on good air exchange. Fourthly, although heating dwellings by in-home biomass burning may reduce carbon dioxide emissions, consequences for health and wellbeing were negative with the technology in use in the cities studied. CONCLUSIONS: The climate-change reduction policies reduced CO2 emissions (the most common greenhouse gas) from cities but impact on global emissions of CO2 would be more limited due to some displacement of emissions. The health and wellbeing impacts varied and were often limited reflecting existing relatively high quality of life and environmental standards in most of the participating cities; the greatest potential for future health benefit occurs in less developed or developing countries.

Protecting children's health from the effects of environmental contamination is a public health priority. In recent years, particular care has been devoted in Italy to the study of the relationship between environmental pollutants and health during infancy. The SENTIERI Project has called attention to increases in infant mortality in National Priority Contaminated Sites (NPCSs). SENTIERI KIDS provides a blueprint for the establishment of a task force charged with establishing multi and inter-disciplinary cooperation between central and regional institutions on the subject of children's health in contaminated sites. SENTIERI KIDS introduces a multiple outcome analytical model based on updated health outcomes (mortality, cancer incidence, hospital discharges) in order to establish a permanent observation system to monitor the state of health of infants residing in contaminated areas. This will pave the way for more in-depth epidemiological enquiries on an individual basis, and support the establishment and continued monitoring of primary prevention projects. Particular attention is devoted to issues of information and communication.

The Istituto Superiore di Sanità (National Institute of Health-ISS), in partnership with a network of Italian national and regional scientific institutions, initiated the SENTIERI Project (Epidemiological Study of Residents in Italian Contaminated Sites-NPCSs), the objectives, methods and initial results of which were published by Epidemiologia & Prevenzione in 2010 and 2011. In the course of 2013, some of the SENTIERI Project findings were published in international scientific journals, and the "SENTIERI approach" was among those sanctioned by the World Health Organization to conduct an initial description of the health status of residents of contaminated sites. The present Report, set up jointly by ISS and the Italian Network of Cancer Registries (AIRTUM), as anticipated in the 2011 Report, aims to provide, for each of the 18 National Priority Contaminated Sites included in the SENTIERI Project where the Italian Association of Cancer Registries is active, a mortality update to 2010, analyses of cancer incidence (1996-2005 in 17 NPCSs) and of hospital discharges (2005-2010), as is explained in detail in Chapter 2, pertaining to the project's materials and methods. The results of the analyses for each NPCS are presented in Chapter 3, while Chapter 4 includes a critical appraisal, a discussion of the methodological approach and a series of concluding remarks. The second section of the Report takes an in-depth look at important issues of public health and scientific research in contaminated sites. This Report represents an important step towards implementing a permanent epidemiological surveillance system in Italy's contaminated sites, the ultimate goal of the SENTIERI Project.

The SENTIERI Project represents the first comprehensive analysis of the health impact of residence in National Priority Contaminated Sites (NPCSs). For the first time, it considers three distinct health outcomes: mortality (2003-2010), cancer incidence (1996- 2005) and hospital discharges (2005-2010). The Report includes a commentary explaining methodology and approach, as well as remarks on the causal association between environmental exposures and investigated health outcomes based on the a priori assessments of the epidemiological evidence; the main implications for public health and scientific research priorities are also presented. The approach put forward by SENTIERI was among those sanctioned by the World Health Organization to conduct an initial description of the health status of residents of contaminated sites. Results relating to individual diseases that can be traced back to a single agent, such as asbestiform fibres, can be easily analysed. The Biancavilla NPCS (where the fluoro-edenite asbestiform fibre was found) displays excesses of pleural mesothelioma and its proxy, malignant pleural tumours, as does Priolo, where asbestos coexists with other pollutants. Increased risk was also recorded in NPCSs adjacent to the coast hosting harbour areas (such as Trieste, Taranto and Venice) or comprising industrial areas specialising in the production of chemicals (Laguna di Grado e Marano, Priolo and Venezia) and steel (Taranto, Terni, Trieste). Increases of pathologies, such as cancer and respiratory diseases, connected to more than one agent, in industrial sites with multiple and diverse sources of exposures, prove harder to interpret. There are also more complex cases in which results do not appear consistent in the three databases or by gender (such as lung cancer in Venice, where mortality and hospital discharges have only increased among women). In order to adequately examine these we must consider factors such as the appropriateness of the health outcome showing the increase, considering latency and the length of the observation period. Of further interest are results relating to diseases of the urinary tract such as kidney failure in the NPCSs of Basso bacino del fiume Chienti, Taranto, Milazzo and Priolo. Overall, the results discussed above are consistent with the previous findings pertaining to mortality for 1995-2002. The present analysis also introduces a new element - the study of cancer incidence and hospital discharges - which can tell us a great deal about diseases with high survival rates or non lethal ones. The first is the case of thyroid cancer, which presents increases in both databases and for both genders in a number of NPCSs (Brescia-Caffaro, Laghi di Mantova, Milazzo, Sassuolo- Scandiano and Taranto). The study of cancer incidence and hospital discharges also revealed cancer excesses for melanoma, breast cancer and non Hodgkin lymphoma in Brescia-Caffaro NPCS where PCBs (Polychlorinated biphenyl) are the site's main pollutant. PCBs, according to the 2013 evaluation of the International Agency for Research on Cancer, are ascertained human carcinogens for melanoma and probable carcinogens for breast cancer and non-Hodgkin lymphoma. The results pertaining to cancer incidence in the 17 NPCSs can also be presented using rankings by area or disease analyzed by a multivariate hierarchical Bayesian model. These rankings reveal an overlapping of credibility intervals, such that it is not possible to speak of a limited number of cancer sites or of certain NPCSs as being particularly affected. Every NPCS, therefore, must be considered individually and ordering them by ranking of cancer incidence wouldn't be appropriate. Data collected concerning some of the NPCSs in the context of the SENTIERI Project is so conclusive that remediation measures can immediately be put in place. This is the case in the Biancavilla and Brescia-Caffaro NPCSs. A similar conclusion can be drawn for complex locations such as Taranto, where, based on the results of SENTIERI Projects and the whole available information, we can safely conclude that exposure to environmental agents played an important role, allowing us to set in place 'Integrated evaluation of environmental and health impact procedures'. SENTIERI approach does not allow definitive causal assessments. However, as stated above, these results do provide a topic for further study without getting in the way of initiatives promoting urgent environmental remediation.

BACKGROUND: Policies on waste disposal in Europe are heterogeneous and rapidly changing, with potential health implications that are largely unknown. We conducted a health impact assessment of landfilling and incineration in three European countries: Italy, Slovakia and England. METHODS: A total of 49 (Italy), 2 (Slovakia), and 11 (England) incinerators were operating in 2001 while for landfills the figures were 619, 121 and 232, respectively. The study population consisted of residents living within 3 km of an incinerator and 2 km of a landfill. Excess risk estimates from epidemiological studies were used, combined with air pollution dispersion modelling for particulate matter (PM10) and nitrogen dioxide (NO2). For incinerators, we estimated attributable cancer incidence and years of life lost (YoLL), while for landfills we estimated attributable cases of congenital anomalies and low birth weight infants. RESULTS: About 1,000,000, 16,000, and 1,200,000 subjects lived close to incinerators in Italy, Slovakia and England, respectively. The additional contribution to NO2 levels within a 3 km radius was 0.23, 0.15, and 0.14 µg/m3, respectively. Lower values were found for PM10. Assuming that the incinerators continue to operate until 2020, we are moderately confident that the annual number of cancer cases due to exposure in 2001-2020 will reach 11, 0, and 7 in 2020 and then decline to 0 in the three countries in 2050. We are moderately confident that by 2050, the attributable impact on the 2001 cohort of residents will be 3,621 (Italy), 37 (Slovakia) and 3,966 (England) YoLL. The total exposed population to landfills was 1,350,000, 329,000, and 1,425,000 subjects, respectively. We are moderately confident that the annual additional cases of congenital anomalies up to 2030 will be approximately 2, 2, and 3 whereas there will be 42, 13, and 59 additional low-birth weight newborns, respectively. CONCLUSIONS: The current health impacts of landfilling and incineration can be characterized as moderate when compared to other sources of environmental pollution, e.g. traffic or industrial emissions, that have an impact on public health. There are several uncertainties and critical assumptions in the assessment model, but it provides insight into the relative health impact attributable to waste management.

SENTIERI Project (Mortality study of residents in Italian polluted sites) studied mortality of residents in the sites of national interest for environmental remediation (Italian polluted sites--IPSs). IPSs are in proximity of either active or dismissed industrial areas, near dumping sites of industrial and hazardous waste or incinerators. SENTIERI Project described and evaluated the mortality of the populations residing in IPSs and it specifically focused on causes of death for which environmental exposure is suspected or ascertained to play an etiologic role. The epidemiological evidence of the causal association was classified a priori into one of these three categories: Sufficient (S), Limited (L) and Inadequate (I). The study results will allow the priorities setting in remediation intervention, so as to prevent adverse health effects from environmental exposure. At the time of 2001 Census, about 10%of Italian population resided in the 44 IPSs included in SENTIERI; the mortality analysis was carried out for the years 1995-2002 for 63 causes of death. The study results for the 44 IPSs are here commented and read on the basis the a priori evaluation of the epidemiological evidence in terms of strength of the causal association, and taking into account the limits of a geographic study design and its implied complexities. The procedures and results of the evidence evaluation have been presented in a 2010 Supplement of Epidemiology & Prevention devoted to SENTIERI.

SENTIERI Project is the first comprehensive study of the health impact of residence in Italian polluted sites (IPSs). The present Chapter examines the main validity aspects of the present mortality investigation and the evaluation of causality of the observed associations; in addition, some recommendations for public health intervention and research priorities in epidemiological studies on environment and health are given. Exposure ascertainment is a key aspect when an ecological study design is adopted in environmental epidemiology, therefore any exposure potentially affecting the population at study should be described in detail. This is here discussed. SENTIERI is an ecological study, based on a priori hypotheses, in which each IPS's types of exposure were described with specific attention to human exposure. Though, when commenting the results, the problem of concurrent air pollution exposure and/or industrial activities implying occupational risk, if present in the IPSs, was taken into account. Socioeconomic status is a determinant of health and disease, therefore in SENTIERI the Standardized Mortality Ratios were computed both crude and adjusted for an ad hoc deprivation index. About 60% versus an expected 40% of IPSs residents are in the two most deprived quintiles of the index. This hints to a possible problem of environmental justice that should be taken into account when planning remediation intervention. The mortality results here presented are a first step in the epidemiological IPSs' characterization, and some developments have been made or planned. Firstly, a mortality analysis was performed combining mortality data in IPSs presenting similar pollution, i.e. asbestos, or industrial hazardous wastes or dumping sites; secondly, the mortality analysis will be extended beyond 2002, namely the year when ICD X started to be in use in Italy. In addition, disease prevalence will be investigated using hospital discharge records; cancer incidence and congenital anomalies incidence will be studied in IPSs in which a Cancer Register or a Congenital Anomalies Register are active. The above described activities will lead to a more valid estimate of the disease burden of IPSs residents, and allow to identify priorities of remediation activities. The method adopted in SENTIERI, specifically the ecological design and the use of mortality data at municipal level, in general does not grant the evaluation of the causal association between environmental exposure and adverse health effects. However, it allows etiological observations that make unacceptable the delay of remediation intervention.

BACKGROUND: The scientific evidence on the health effects of waste-related exposure is not conclusive. Differential exposure to waste by socio-economic status (SES) is often documented, but the interplay between environmental and social factors, crucial for policy making, is not well known. This review aims at investigating the role of health inequalities and inequities in waste management. METHODS: Grey and peer-reviewed literature, published after 1983, was reviewed from Europe and the USA. RESULTS: Available data provide consistent indications that waste facilities are often disproportionally more located in areas with more deprived residents, or from ethnical minorities. This applies to waste incinerators, landfills, hazardous waste sites, legal and illegal. In studies considering health effects (mainly from Europe), risks are estimated with standardization for SES. Such standardization almost always decreases risk estimates for several cancers and reproductive outcomes. However, effect modification is not investigated in these studies. CONCLUSIONS: The patterns of association between waste-related environmental pressures and SES suggest that some of the observed inequalities in exposure and health represent a case of environmental injustice as they are the result of social processes and may be prevented, at least partly. Disentangling the possible health effects remains difficult, due to limitations in the methodology. It seems important to investigate if disadvantaged people are more vulnerable, i.e. risks differ in different social groups living in the same area. Notwithstanding these open questions, public health officers and decision makers should identify waste management policies to minimize their potential health impacts and their unequal distribution.

BACKGROUND: In spring 2013, groundwater of a vast area of the Veneto Region (northeastern Italy) was found to be contaminated by perfluoroalkyl substances (PFAS) from a PFAS manufacturing plant active since the late 1960s. Residents were exposed to high concentrations of PFAS, particularly perfluorooctanoic acid (PFOA), through drinking water until autumn 2013. A publicly funded health surveillance program is under way to aid in the prevention, early diagnosis, and treatment of chronic disorders possibly associated with PFAS exposure. OBJECTIVES: The objectives of this paper are: a) to describe the organization of the health surveillance program, b) to report serum PFAS concentrations in adolescents and young adults, and c) to identify predictors of serum PFAS concentrations in the studied population. METHODS: The health surveillance program offered to residents of municipalities supplied by contaminated waterworks includes a structured interview, routine blood and urine tests, and measurement of 12 PFAS in serum by high-performance liquid chromatography-tandem mass spectrometry. We studied 18,345 participants born between 1978 and 2002, 14-39 years of age at recruitment. Multivariable linear regression was used to identify sociodemographic, lifestyle, dietary, and reproductive predictors of serum PFAS concentrations. RESULTS: The PFAS with the highest serum concentrations were PFOA [median 44.4 ng/mL, interquartile range (IQR) 19.3-84.9], perfluorohexanesulfonic acid (PFHxS) (median 3.9 ng/mL, IQR 1.9-7.4), and perfluorooctanesulfonic acid (PFOS) (median 3.9 ng/mL, IQR 2.6-5.8). The major predictors of serum levels were gender, municipality, duration of residence in the affected area, and number of deliveries. Overall, the regression models explained 37%, 23%, and 43% of the variance of PFOA, PFOS, and PFHxS, respectively. CONCLUSIONS: Serum PFOA concentrations were high relative to concentrations in populations with background residential exposures only. Interindividual variation of serum PFAS levels was partially explained by the considered predictors. https://doi.org/10.1289/EHP5337.

The possible adverse health effects associated with the residence in the neighbourhood of toxic dump sites have been the object of many epidemiological studies in the last two decades;some of these reported increases of various health outcomes. The present study reports the cluster analysis of mortality and malformations at municipality level, standardized by socioeconomic deprivation index, in an area of the Campania Region characterized by a widespread illegal practice of dumping toxic and urban waste. Clusters have been observed with significant excess of mortality by lung, liver, gastric, kidney and bladder cancers and of prevalence of total malformations and malformations of limb, cardiovascular and urogenital system. The clusters are concentrated in a sub-area where most of the illegal practice of dumping toxic waste has taken place

OBJECTIVE: to estimate the health impact of ozone in 13 Italian cities over 200,000 inhabitants and to produce basic elements to permit the reproducibility of the study in other urban locations. DESIGN: the following data have been used: population data (2001), health data (2001 or from scientific literature), environmental data (2002-2004), from urban background monitoring station and concentration/response risk coefficients derived from recent metanalyses. The indicators SOMO35 and SOMO0 have been used as a proxi of the average exposure to calcolate attributable deaths (and years of life lost) and several causes of morbility for ozone concentrations over 70 microg/m3. MAIN OUTCOME MEASURE: acute mortality for all causes and for cardiovascular mortality, respiratory-related hospital admissions in elderly, asthma exacerbation in children and adults, minor restricted activity days, lower respiratory symptoms in children. RESULTS: over 500 (1900) deaths, the 0.6% (2.1%) of total mortality, equivalent to about 6000 (22,000) years of life lost are attributable to ozone levels over 70 microg/m3 in the 13 Italian cities under study. Larger figures, in the order of thousands, are attributable to less severe morbidity outcomes. CONCLUSION: The health impact of ozone in Italian towns is relevant in terms of acute mortality and morbidity, although less severe than PM10 impact. Background ozone levels are increasing. Abatement strategies for ozone concentrations should consider the whole summer and not only "peak" days and look at policies limiting the concentration of precursors produced by traffic sources. Relevant health benefits can be obtained also under levels proposed as guidelines in the present environmental regulations.

Despite sound scientific knowledge and evidence that any exposure to asbestos fibers in all of its forms, are carcinogenic to humans, its presence, use and trade is still substantial, including in the World Health Organization (WHO) European Region. Banning the production and use of all forms of asbestos, as recommended by the International Labour Organization (ILO) and WHO, has been proven as the most efficient evidence-based strategy to eliminate Asbestos Related Diseases (ARDs). To effectively move elimination of ARDs forward, attaining a greater understanding of key stakeholders perspectives was identified as an important action. The WHO Regional Office for Europe, the European Centre for Environment and Health, undertook semi-structured interviews, and follow-up discussions with diverse representatives dealing professionally with asbestos. The interview questionnaire was developed based on the current ARDs WHO Report, the Evidence Implementation Model for Public Health and categories of the theory of diffusion. Data were attained on three main questions within the interview questionnaire: (1) Identifying barriers to implementation of WHO evidence-based asbestos recommendations; (2) Describing roles of key stakeholders; and, (3) Proposing possible solutions. The results demonstrated use of sound and convincing scientific evidence along with economic evidence and facilitators can be used to achieve evidence-based policy development, and comprehensive diverse actions.
