Introduction: Environmental heavy metals exposure has been associated with kidney disease. There is also some evidence that exposure to solvents may be a risk factor for kidney disease. We estimated the risk of hospitalization for kidney diseases (ICD-9 580-586) and chronic kidney disease (CDK, ICD-9 585) in residents in thirty-four Italian National Priority Contaminated Sites (NPCSs) polluted by heavy metals., Methods: Random-effects model meta-analyses of SHR (Standard Hospitalization Ratio) computed for each NPCS was performed for all the NPCSs together, and separately, according to the presence/absence of selected industrial activities (petrochemical/refinery and steel plants), and the presence/absence of solvents contamination., Results: Pooled SHRs of overall NPCSs were in excess in both genders. Statistically significant excesses were found for CKD in both genders, and for kidney diseases in females, residing in NPCSs with the combined presence of heavy metals and solvents contamination. The pooled SHRs for CKD and kidney diseases were not statistically significant in excess in NPCSs with petrochemical/refinery and steel plants, and only petrochemical/refinery plants., Conclusions: The results are suggestive of a possible kidney disease risk in population living in the above-mentioned NPCSs. Epidemiological surveillance and remediation actions in these areas are recommended.

Introduction: The limited scientific knowledge on the relationship between exposure and health effects in relation to geothermal activity motivated an epidemiologic investigation of Tuscan geothermal area., Aim: This study aims at describing mortality of populations living in Tuscan municipalities in the period 2003-2012., Method: Sixteen municipalities were included in the study area: eight in the northern and eight in the southern area. Mortality data come from the Regional Mortality Registry of Tuscany. Fifty-four causes of death, considered of interest for population health status or consistent with "Project SENTIERI" criteria, are analyzed., Results: Results show a worse mortality profile in the southern area, especially in males, for whom excesses of all cancers and some causes of cancer emerge, while in the northern area an excess of cerebrovascular diseases among females merits attention. Further and more appropriate studies are needed to clarify the etiology of some diseases and to better assess a potential cause-effect relationship.

Introduction: The association between reproductive health outcomes and exposure to municipal solid waste incinerators (MSWIs) is inconclusive. This study investigates the association between exposure to a MSWI and various reproductive outcomes (preterm birth, low birth weight, small for gestational age, and sex ratio), taking into account other sources of pollution (industrial plants, highway, major roads with high traffic flows) and maternal factors, including the socioeconomic status., Methods: PM10 concentration maps were used for the exposure assessment to the MSWI and to other sources of pollution in the study area. Information on resident births and maternal covariates were selected from the delivery certificates referred to the period 2001-2010. Mothers' addresses were geocoded in order to attribute the individual level of exposure. Odds ratios (ORs) with a 95% confidence interval (CI) adjusted for maternal covariates and exposure to other pollution sources were calculated., Results: A total of 3153 newborns to 2401 mothers residing in area during the study period were analyzed. A risk of preterm birth associated with increased exposure was detected (OR = 1.61; 95% CI: 0.88-2.94; p test for trend 0.098). When newborns to primiparous women were considered an OR of 2.18 (95% CI: 1.05-4.53) and a significant trend were observed (p = 0.033). No significant results for the other investigated outcomes were observed., Conclusions: The study detected a slight association between exposure at MSWI and preterm births. The results are in agreement with those of a previous multi-site study with similar design, and they strengthen the recommendation to consider gestational age in studies and surveillance in areas with MSWIs and similar sources of pollution.

Objectives: Adverse effects of waste management represent a public health issue. Mortality meta-analysis in Italian National Priority Contaminated Sites (NPCSs) with industrial waste landfills or illegal dumps is presented., Methods: 24 NPCSs include industrial waste landfills or illegal dumps. Class 1 (10 NPCSs with industrial waste landfills) and Class 2 (14 NPCSs with illegal dumps) were categorized. Random-effects model meta-analyses of Standardized Mortality Ratios non-adjusted (SMRs) and adjusted for Deprivation (DI-SMRs) computed for each CS (1995-2002) were performed for overall 24 NPCSs and the two classes. The North- Southern gradient was considered., Results: 24 CSs pooled-SMRs are significantly increased in both genders for cancer of liver (men: SMR=1.13; women: SMR=1.18), bladder (men: SMR=1.06; women: SMR=1.11), and for cirrhosis (men: SMR=1.09; women: SMR=1.13). In Class 2 the increase is confirmed in both genders for liver and bladder cancers and for cirrhosis and in men only for lung cancer. Congenital anomalies and adverse perinatal conditions are not increased., Conclusion: The results are consistent with the hypothesis of adverse health effects of non-adequately managed hazardous waste. Causal interpretation is not allowed, but the meta-analytic approach provides more confidence in the findings.

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
