[The mortality cost of carbon dioxide emissions from a steel plant in Southern Italy: a climate change health impact assessment]. / Il "mortality cost" delle emissioni di CO2 di uno stabilimento siderurgico nel Sud Italia: una valutazione degli impatti sanitari derivanti dal cambiamento climatico.

OBJECTIVES: to quantify the temperature-related global health impacts of the Taranto steel plant CO2e emissions. DESIGN: using the risk functions available in the literature, a prospective global health impact assessment of the marginal CO2e emissions declared by the steel plant for 2020 was conducted. SETTING AND PARTICIPANTS: world population in the period 2020-2100. MAIN OUTCOMES MEASURES: deaths in the period 2020-2100 attributable to the marginal CO2e emitted by the Taranto steel plant in 2020. RESULTS: considering the central estimates in the baseline emission scenario (4.1°C warming by 2100), the Taranto steel plant 2020 CO2e emissions will cause 1,876 deaths worldwide between 2020 and 2100. The largest part will be attributable to steelmaking processes, accounting for 1,093 deaths. The same emissions will cause 5.56 × 10-4 deaths worldwide between 2020 and 2100 per tonne of steel produced in 2020, i.e. one death for every 1,799 tonnes of steel. If the 2020 CO2e emissions of the steel plant had been reduced by 25%, 50% or 75%, the deaths avoided in the world in the period 2020-2100 would have been 469, 938 and 1,407 respectively. CONCLUSIONS: estimates predict a probably significant mortality impact worldwide by the end of the century associated with the greenhouse gases emissions of the Taranto steel plant. Just reducing emissions by 50% in a single year could maybe avoid over 900 deaths worldwide by the end of the century. This confirms the importance of implementing incisive policies to reduce greenhouse gases emissions in all sectors.

Vaccines in older age: moving from current practice to optimal coverage-a multidisciplinary consensus conference.

Vaccines are a key strategy to promote healthy aging, but vaccine coverage remains below target levels in at-risk adults and older individuals. We present here the results of a multidisciplinary consensus conference convened to perform a multidimensional assessment of vaccination in geriatric medicine, with a view to developing a well-defined strategy for the promotion of vaccines in older people. We discuss recommended vaccines in older individuals, and describe the wide regional heterogeneity between regions in the Italian context. The main obstacles to implementation of vaccines in practice are reviewed, as well as potential strategies to remove these barriers. Finally, the importance of including vaccines and vaccination in undergraduate and postgraduate medical education is underlined. The information summarized in this document is expected to help develop educational and promotional initiatives to achieve greater uptake of vaccines among older individuals, as a key means to promote healthy aging.

Neurocognitive impact of metal exposure and social stressors among schoolchildren in Taranto, Italy.

BACKGROUND: Metal exposure is a public health hazard due to neurocognitive effects starting in early life. Poor socio-economic status, adverse home and family environment can enhance the neurodevelopmental toxicity due to chemical exposure. Disadvantaged socio-economic conditions are generally higher in environmentally impacted areas although the combined effect of these two factors has not been sufficiently studied. METHODS: The effect of co-exposure to neurotoxic metals including arsenic, cadmium, manganese, mercury, lead, selenium, and to socio-economic stressors was assessed in a group of 299 children aged 6-12 years, residing at incremental distance from industrial emissions in Taranto, Italy. Exposure was assessed with biological monitoring and the distance between the home address and the exposure point source. Children's cognitive functions were examined using the Wechsler Intelligence Scale for Children (WISC) and the Cambridge Neuropsychological Test Automated Battery (CANTAB). Linear mixed models were chosen to assess the association between metal exposure, socio-economic status and neurocognitive outcomes. RESULTS: Urinary arsenic, cadmium and hair manganese resulted inversely related to the distance from the industrial emission source (ß - 0.04; 95% CI -0.06, - 0.01; ß - 0.02; 95% CI -0.05, - 0.001; ß - 0.02 95% CI -0.05, - 0.003) while the WISC intellectual quotient and its sub-scores (except processing speed index) showed a positive association with distance. Blood lead and urinary cadmium were negatively associated with the IQ total score and all sub-scores, although not reaching the significance level. Hair manganese and blood lead was positively associated with the CANTAB between errors of spatial working memory (ß 2.2; 95% CI 0.3, 3.9) and the reaction time of stop signal task (ß 0.05; 95% CI 0.02, 0.1) respectively. All the other CANTAB neurocognitive tests did not show to be significantly influenced by metal exposure. The highest socio-economic status showed about five points intellectual quotient more than the lowest level on average (ß 4.8; 95% CI 0.3, 9.6); the interaction term between blood lead and the socio-economic status showed a significant negative impact of lead on working memory at the lowest socio-economic status level (ß - 4.0; 95% CI -6.9, - 1.1). CONCLUSIONS: Metal exposure and the distance from industrial emission was associated with negative cognitive impacts in these children. Lead exposure had neurocognitive effect even at very low levels of blood lead concentration when socio-economic status is low, and this should further address the importance and prioritize preventive and regulatory interventions.

Preventing and managing herpes zoster: key actions to foster healthy aging.

Population aging is the demographic phenomenon characterizing all countries in the world, and it is challenging the national infrastructures, in particular health systems. However, aging itself is not associated with increased medical spending, but disability and comorbidity that affect older individuals are the actual drivers for health expenditures. Therefore, if people age in better health, medical spending may be significantly reduced. Preventative interventions proved to be effective in reducing/preventing disease and disability and often found to be cost effective, include diet and exercise interventions, medications, routine disease screenings, and immunizations. Vaccination can protect older citizens against life-threatening diseases, such as influenza, pneumococcal infections, tetanus, and against diseases which adversely impact their quality of life, such as herpes zoster (HZ). Including HZ vaccination in its citizens' lifetime immunization calendar can reinforce Europe's commitment toward active, healthy aging. This paper outlines the consensus statement of a group of Italian experts on HZ.

[Universal vaccination against varicella in Italy: the same opportunity for all children]. / La vaccinazione universale contro la varicella in Italia: una questione di equità.

Varicella is an infectious disease still frequent in Italy, where 8 out 20 Regions have adopted universal vaccination programs starting from 2003. Accordingly to National Vaccination Plan, all Regions should introduce universal varicella vaccination in 2015. An independent multidisciplinary group of experts met to discuss some debated questions. The available evidence of varicella vaccine efficacy in the 8 Regions was evaluated and the evidence of safety of monovalent and combined varicella vaccines are presented. The strategy for introducing universal varicella vaccine in the pediatric immunization schedule is discussed. The expert group concludes that available evidence supports the active offer of varicella vaccine in all Italian Regions and that catch up programs for susceptible cohorts should be encouraged.

[Prevention of HPV cancer related through HPV-9: state of the art, potential benefits and open issues]. / HPV-9 e prevenzione dei tumori HPV correlati: stato dell'arte, potenziali benefici e problemi aperti.

HPV vaccines currently marketed in Italy (bivalent and quadrivalent against HPV 16-18 and HPV and 6,11,16,18 respectively) are an extraordinary tool for the primary prevention of HPV related diseases, particularly of the cervical cancer. Although the implementation of the organized vaccination programs has already translated (for some endpoint) in confirmation of clinical efficacy, remains excluded a significant proportion of the diseases linked to non-vaccine HPV types. The new nonavalent vaccine (HPV9), of impending commercialization, represents an evolution of the quadrivalent, the composition of which are added five high-risk HPV types (HPV 31,33,45,52,58). The high clinical-immunological efficacy in experimental trials against the new genotypes (> 96% for CIN2 +), and the equivalence immunogenic to the four already present in the previous vaccine, will render the use of HPV9 a tool able to control in an even more effective HPV disease. The potential of the new vaccine is linked to the reduction of the HPV cancer burden by 2-20% according to anatomical site, with major benefits for cervical cancer, vulvo-vaginal, penile and more limited benefits for anal tumours. Moreover, the potential benefits could be also linked to the reduction of incidence of pre-neoplastic lesions arising in the lower-genital tract, especially in the cervix (CIN2-3), so often cause lengthy and expensive diagnostic and therapeutic procedures. In the face of this broad provision of benefit from HPV9 vaccine, we have also to consider all the variables related to its introduction in the vaccination calendars: the market price, the schedule of administration (currently in three doses) and data regarding the cost-effectiveness. The authors recognize the new vaccine (currently registered only in the US) a lot of potential in the prevention of HPV-related diseases.

Update on the epidemiology of tuberculosis in Italy.

As in many countries in Western Europe, in Italy tuberculosis (TB) is a relatively rare disease. In the last decade its incidence has remained constant at under 10 cases/100,000 inhabitants, the threshold considered to define a country as low prevalence. The epidemiological picture, however, is very different in the countries of Eastern Europe and in Africa, Asia, and Latin America, where the incidence of TB continues to increase and in some cases is accompanied by the emergence and spread of multidrug-resistant TB. The present review describes the epidemiology of TB in Italy. In 2008, the incidence rate was 3.8 cases per 100,000 for people born in Italy, and 50-60 cases per 100,000 for those born abroad. There was an increase in cases from Eastern Europe. The crude mortality rate for TB in 2006 was 0.7 deaths per 100,000 residents. Although TB is a low-prevalence disease in Italy, its epidemiology is changing. Since 1955, more than 160,000 people in Italy have died from this potentially preventable and curable disease.

[Herpes Zoster and its prevention in Italy. Scientific consensus statement]. / L'Herpes Zoster e la prevenzione vaccinale in Italia. Documento scientifico di consenso.

In this paper, an Italian group of experts presents a revision of the available data about epidemiology and prevention of Herpes Zoster (HZ). HZ is an acute viral diseases caused by the reactivation of Varicella Zoster Virus (VZV). HZ is characterized by neurological and dermatological symptoms with a dermatomeric localization. The reactivation of the virus from the latent status in the sensitive ganglia increases with age and failing cell mediated immunity. In Europe, more than 95% of adults presents antibodies against VZV. Incidence of HZ is similar all over the world, related to the age of the population: from 2-3/1000 persons/year in the age group 20 to 50 years to 5/1000 in the 60 years old, 6-7/1000 between 70 and 80 up to >1/100 in older than 80. In Italy, about 157,000 new cases of HZ are estimated every year with an incidence of 6.3/1000 persons/year mostly in older adults. Among the hospitalized cases, 60% are over 65 years of age. The more frequent and severe complication of HZ is post herpetic neuralgia (PHN), characterized by severe localized pain lasting at least 3 month after the beginning of the acute phase. The pain is responsible for a sharp decrease in the quality of life. In Europe, PHN is described in 2.6-27% of HZ cases. In Italy, data obtained by a network of General Practitioner show PHN in 20.6% of HZ patients, while 9.2% of the patients still presents PHN at 6 months. The more frequent localization is thoracic; when the virus reactivate at the level of the ophthalmic division of the trigeminal nerve most patients develop ocular complications. The clinical and therapeutical managements of HZ patients is difficult and the results are often poor. Prevention of HZ e PHN in the population over 50 years is possible using a live attenuated vaccine containing VZV (Oka/Merck strain, not less than 19.400 plaque forming units), available since 2006. Efficacy of anti-HZ vaccine was demonstrated in two large clinical trials that showed a 51% reduction in the incidence of HZ and a 61% decrease of the burden of illness. Incidence of PHN showed a reduction of 67% in immunized subjects. Long-term follow-up showed a persistence of the protection even if a decrease was noted in older subjects and with time. Effectiveness studies confirm the data of clinical trials and numerous pharmaco-economical evaluation show a favorable profile of HZ vaccine. The vaccine is recommended in USA, Canada and some European countries for people over 60. The expert group concluded that HZ and PHN represent an important clinical and Public Health problem in Italy and that the possibility to prevent them should be carefully evaluated.

Mapping and ranking outcomes for the evaluation of seasonal influenza vaccine efficacy and effectiveness: a delphi study.

BACKGROUND: Protection provided by seasonal influenza vaccination (SIV) may be measured against numerous outcomes, and their heterogeneity may hamper decision-making. The aim of this study was to explore outcomes used for estimation of SIV efficacy/effectiveness (VE) and obtain expert consensus on their importance. RESEARCH DESIGN AND METHODS: An umbrella review was first conducted to collect and map outcomes considered in systematic reviews of SIV VE. A Delphi study was then performed to reach expert convergence on the importance of single outcomes, measured on a 9-point Likert scale, in principal target groups, namely children, working-age adults, older adults, subjects with co-morbidities and pregnant women. RESULTS: The literature review identified 489 outcomes. Following data reduction, 20 outcomes were selected for the Delphi process. After two Delphi rounds and a final consensus meeting, convergence was reached. All 20 outcomes were judged to be important or critically important. More severe outcomes, such as influenza-related hospital encounters and mortality with or without laboratory confirmation, were generally top-ranked across all target groups (median scores ≥8 out of 9). CONCLUSIONS: Rather than focusing on laboratory-confirmed infection per se, experimental and observational VE studies should include more severe influenza-related outcomes because they are expected to exercise a greater impact on decision-making.

PCDD/Fs and PCBs in hen eggs from a contaminated area in Italy: a 9 years spatio-temporal monitoring study.

Eggs can represent a food susceptible to contamination, with bioaccumulation potential for POPs. The Province of Taranto, Southern Italy, is of particular relevance in this context because of the presence of industrial sources of PCDD/Fs and PCBs. The aim of this study was to analyze and report the levels of these contaminants in hen eggs sampled in farms located within a radius of 20 km from the industrial area of Taranto. Between 2013 and 2021, 227 hen eggs were collected, according to a special monitoring plan of the Prevention Department. Samples were analyzed by the National Reference Laboratory for Halogenated POPs in Feed and Food. Median (IQR) values were: 0.28 (0.59) pg WHO-TEQ/g fat for PCDD/Fs, 0.89 (1.70) pg WHO-TEQ/g fat for PCDD/Fs + DL-PCBs, 0.57 (1.16) pg WHO-TEQ/g fat for DL-PCBs, 2.24 (5.51) ng/g fat for NDL-PCBs. Samples not-compliant (Reg. 1881/2006/EC and amendments) for at least one contaminant were 17 (7.5%). No contaminants values or exceedances showed a statistically significant correlation with distance from industrial area (p > 0.05). Higher PCDD/Fs values were observed in first and second quarters (p < 0.05). All contaminants' values pairwise combinations showed significant (p < 0.0001) strong (ρ > 0.7) correlation. According to our epidemiological investigations, the exceedances are to be attributed to factors mainly related to farmers' wrong habits. These results confirmed the importance of the monitoring of contaminants' levels in the matrices at risk as well as to focus on enhancing good management practices on eggs-producing farms.

[Exploratory biomonitoring study among workers of livestock farms of the Taranto Province]. / Studio esplorativo di biomonitoraggio tra gli allevatori delle masserie della Provincia di Taranto.

OBJECTIVE: to conduct a survey on blood levels of metals and organochlorine compounds (dioxins and PCBs) among workers of livestock farms, and to identify the factors able to explain the magnitude and variability of the measured concentrations. DESIGN: exploratory human biomonitoring study. SETTING AND PARTICIPANTS: a sample of 45 workers from farms (masserie) located in the Province of Taranto was included in the study. The farms, located between 6 and 43 km from the industrial area, are family owned and animals (mainly sheep and goats) are locally reared outdoors. The study subjects have similar eating habits, including food consumption resulting from their production. RESULTS: manganese concentrations and, to a lesser extent, arsenic, cadmium and lead are in the medium-high range of levels observed in the Italian general population. This study does not identify factors able to explain the variability in the blood levels of metals. The amount of dioxins and PCBs, on the other hand, is strongly associated both with subjects age and the distance of farm from the industrial site. CONCLUSION: the results of this survey are suggestive of research hypotheses that need to be confirmed by biomonitoring studies of adequate design and size, in particular the hypothesis that the blood level of dioxins and PCBs decreases with increasing distance from the industrial site. We recommend ad hoc studies to better characterize the exposure of farmers (also associated with agricultural activities), and of the inhabitants of Taranto, to environmental persistent pollutants, also in terms of food matrices locally produced and consumed.

Experts' Opinion for Improving Pertussis Vaccination Rates in Adolescents and Adults: A Call to Action.

This article highlights the importance of diphtheria-tetanus-acellular pertussis (with reduced antigen content, dTap) vaccination in preventing pertussis, a respiratory infection that is still widespread and easily transmitted. In particular, it highlights the need to receive a booster vaccination throughout life to maintain high antibody levels, which decrease through time. This document collects the opinions that emerged from the comparison between major Italian experts in the field of vaccination. This working group was created to promote a "call to action", aimed at raising awareness among all institutions, public health authorities, and health workers involved in the vaccination process, about the importance of dTap vaccine administration and with the mindset of implementing the strategic vaccination plan provided by the National Vaccine Plan (NVP). In fact, despite this vaccine being included in the NVP, there are some issues attributable to the practice of vaccination (local health authorities, vaccination centers, occupational health services, gynecology centers, societies of work). Therefore, it is necessary that the Ministry defines the vaccination coverage objectives, identifies the groups of subjects who should receive the booster vaccine (subjects exposed to greater risk of infection, subjects over 60, pregnant women), and applies all the necessary measures to encourage the implementation of this practice.

HPV Vaccination during the COVID-19 Pandemic in Italy: Opportunity Loss or Incremental Cost.

OBJECTIVES: Italy was the first European country to introduce universal vaccination of adolescents, for both males and females, against Human Papilloma Virus (HPV) starting in 2017 with the NIP 2017-2019's release. However, vaccine coverage rates (VCRs) among adolescents have shown a precarious take-off since the NIP's release, and this situation worsened due to the impact of the COVID-19 pandemic in 2020. The aim of this work is to estimate the epidemiological and economic impact of drops in VCRs due to the pandemic on those generations that missed the vaccination appointment and to discuss alternative scenarios in light of the national data. METHODS: Through an analysis of the official ministerial HPV vaccination reports, a model was developed to estimate the number of 12-year-old males and females who were not vaccinated against HPV during the period 2017-2021. Based on previously published models that estimate the incidence and the economic impact of HPV-related diseases in Italy, a new model was developed to estimate the impact of the aggregated HPV VCRs achieved in Italy between 2017 and 2021. RESULTS: Overall, in 2021, 723,375 girls and 1,011,906 boys born between 2005 and 2009 were not vaccinated against HPV in Italy (42% and 52% of these cohorts, respectively). As compared with the 95% target provided by the Italian NIP, between 505,000 and 634,000 girls will not be protected against a large number of HPV-related diseases. For boys, the number of the unvaccinated population compared to the applicable target is over 615,000 in the 'best case scenario' and over 749,000 in the 'worst case scenario'. Overall, between 1.1 and 1.3 million young adolescents born between 2005 and 2009 will not be protected against HPV-related diseases over their lifetime with expected lifetime costs of non-vaccination that will be over EUR 905 million. If the 95% optimal VCRs were achieved, the model estimates a cost reduction equal to EUR 529 million, the net of the costs incurred to implement the vaccination program. CONCLUSION: Suboptimal vaccination coverage represents a missed opportunity, not only because of the increased burden of HPV-related diseases, but also in terms of economic loss. Thus, reaching national HPV immunization goals is a public health priority.

PCDD/Fs and PCBs in Mytilus galloprovincialis from a contaminated area in Italy: the role of mussel size, temperature and meteorological factors.

Mussels represent a food at risk of contamination because they are filter-feeding organisms with high bioaccumulation and low biotransformation potential for organic contaminants. Taranto, Southern Italy, is of particular relevance in this context due to the presence of industrial sources of POPs. The aim of this study was to analyse the role of mussel size, temperature and other meteorological factors in determining PCDD/Fs and PCBs concentrations in mussels. Mussels were collected on a monthly basis with random sampling between 2012 and 2020 according to the extraordinary monitoring plan of the Prevention Department. Samples were analysed by the National Reference Laboratory for Halogenated POPs in food and feed. A total of 787 mussel samples were collected between 2012 and 2020. Higher median concentrations were observed in Mar Piccolo First Inlet: PCDD/Fs 1.49 pg WHO-TEQ/g ww; PCDD/Fs + DL-PCBs 6.35 pg WHO-TEQ/g ww; DL-PCBs 4.74 pg WHO-TEQ/g ww; NDL-PCBs 65.10 ng/g ww. In all basins, PCDD/Fs + DL-PCBs, DL-PCBs and NDL-PCBs showed higher concentrations in mussels ≥ 5 cm. Temperature showed positive association with all pollutants in all basins. Higher relative humidity was associated with higher concentrations of some pollutants, while number of rain days was associated with lower values. Our findings showed higher PCDD/Fs and PCBs concentrations in adult mussels, with dependence on temperature and some other meteorological factors. These results could help guide public health strategies and mussel sampling according to mussel size and meteorological conditions in areas affected by POPs contamination.

Monkeypox Virus Infections in Southern Italy: Is There a Risk for Community Spread?

The ongoing outbreak of the Monkeypox virus (MPXV) is characterized by sustained human-to-human transmission, particularly among men who have sex with men (MSM). The aim of the study was to describe the characteristics of the MPXV infection identified in Southern Italy. Clinical samples for each suspected case identified from 1 June to 1 August 2022 were tested for MPXV, and whole-genome sequencing (WGS) was performed on two strains. Ten cases were identified: eight were young adult males, including six MSMs, and two were female. Nine subjects reported recent sexual exposure. One female subject without sexual exposure only reported attendance at a social gathering. Overall, 7 of 10 skin lesion samples had a high viral load of MPXV DNA, and 6/9 whole blood samples and 6/8 nasopharyngeal swab samples also tested positive. The analyzed sequences belonged to Clade 3, lineage B.1, and B.1.5, respectively. Despite this recent multinational outbreak of MPXV cases having revealed a high proportion of cases occurring among MSM, the identification of cases among heterosexual subjects and in a female subject without sexual risk factors should raise awareness among clinicians about the possible spread of MPXV in the general population.

Manifesto on the Value of Adult Immunization: "We Know, We Intend, We Advocate".

Immunization through vaccination is a milestone achievement that has made a tremendous contribution to public health. Historically, immunization programs aimed firstly to protect children, who were disproportionally affected by infectious diseases. However, vaccine-preventable diseases can have significant impacts on adult mortality, health, and quality of life. Despite this, adult vaccinations have historically been overlooked in favor of other health priorities, because their benefits to society were not well recognized. As the general population is aging, the issue of vaccination in older adults is gaining importance. In high-income countries, recommendations for the routine vaccination of older adults have been gradually introduced. The Italian National Immunization Plan is considered to be among the most advanced adult vaccination plans in Europe. However, available data indicate there is low adherence to vaccination recommendations in Italy. The COVID-19 pandemic has exposed the damage that can be caused by an infectious disease, especially among adults and individuals with comorbidities. The aim of this "Manifesto", therefore, is to provide an overview of the existing evidence on the value of adult vaccination, in the Italian context, with a call to action to healthcare providers and health authorities.

Dioxins and PCBs contamination in milk and dairy products from Province of Taranto (Puglia Region, Southern Italy): a six years spatio-temporal monitoring study.

INTRODUCTION: Taranto Province (Puglia Region, Southern Italy) is of particular Public Health relevance due to the presence of industrial sources of dioxins and PCBs. The aim of this study was to analyze the spatio-temporal distribution of these pollutants in milk and cheese produced from 2013 to 2018. MATERIALS AND METHODS: Raw milk and dairy products were sampled in the farms located within 20 km from the industrial area. RESULTS: 1005 milk samples were collected. Median (IQR) concentrations were: dioxins 0.21 (0.21) pg WHO-TEQ/g fat; dioxins+DL-PCBs 0.83 (0.71) pg WHO-TEQ/g fat; NDL-PCBs 1.92 (1.56) ng/g fat. Overall, only 6 (0.6%) samples were found to be non-compliant for at least one pollutants group. Temporal analysis showed a decreasing trend in dioxins and PCBs concentrations over the observed years and higher values in the first trimester. Spatial analysis showed higher levels of PCBs in areas closest to the industrial pole. 70 dairy products samples were collected. Median pollutants concentrations were far below the EU limits and no exceedances were observed. CONCLUSIONS: The extremely low number of exceedances appeared as an encouraging result and supported the validity of the Public Health measures adopted by the Department of Prevention of Taranto.

The effects of the exposure to neurotoxic elements on Italian schoolchildren behavior.

Neurodevelopmental disorders are constantly increasing on a global scale. Some elements like heavy metals are known to be neurotoxic. In this cross-sectional study we assessed the neurobehavioral effect of the exposure to trace elements including lead, mercury, cadmium, manganese, arsenic and selenium and their interactions among 299 schoolchildren residing in the heavily polluted Taranto area in Italy. Whole blood, urine and hair were collected for metal analyses, while the Child Behavior Checklist and the Social Responsiveness Scale, administered to the main teacher and the mothers were considered to identify behavioral problems in children. Blood lead mainly influenced social problems, aggressive behavior, externalizing and total problems. Urinary arsenic showed an impact on anxiety and depression, somatic problems, attention problems and rule breaking behavior. A significant interaction between lead and arsenic was observed, with a synergistic effect of the two metals increasing the risk of attention problems, aggressive behavior, externalizing problems and total problems. Overall, we were able to test that higher blood lead, urinary arsenic concentrations and their interaction increase the risk of neurobehavioral problems. This is in line with the U.S. Environmental Protection Agency's priority list of hazardous substances where arsenic and lead are ranked as first and second respectively.

Dioxins and PCBs contamination in mussels from Taranto (Ionian Sea, Southern Italy): a seven years spatio-temporal monitoring study.

INTRODUCTION: Taranto is of particular Public Health relevance for the presence of industrial sources of dioxins and PCBs. The aim of this study was to monitor these pollutants in mussels produced from 2012 to 2018. MATERIALS AND METHODS: Mussels were collected on a monthly basis with random sampling. Concentrations were determined through accredited methods. RESULTS: 622 samples were collected. Dioxins and PCBs showed higher median concentrations in Mar Piccolo 1st Inlet (p s <0.0001; Dioxins: 1.43 pg WHO-TEQ/g ww; Dioxins+DL-PCBs: 5.98 pg WHO-TEQ/g ww; DL-PCBs: 4.57 pg WHO-TEQ/g ww; NDL-PCBs: 61.54 ng/g ww) and in III trimester for all basins (p s <0.02). In Mar Piccolo 1 st Inlet, there was a linear increase of dioxins and PCBs moving North (p s <0.05). CONCLUSIONS: These findings confirmed higher concentrations in Mar Piccolo 1 st Inlet during the summer period and supported the validity of the Public Health measures adopted by the Department of Prevention of Taranto.
