ABSTRACT
BACKGROUND: Contaminated sites are among the main worldwide environmental health priorities. The health impact on population living in Italian contaminated sites of national concern for remediation (CSs) with petrochemical/refineries (P&R) and steel plants (S) was estimated. Since these CSs include the major Italian facilities located widespread on the territory are representative of the national reality. Furthermore, the population exposed in P&R and S is significant since it represents about 3% of the national population.
METHODS: Two groups of CSs were defined: twelve CSs with P&R and eight with S. Cause-specific mortality (2013-2017) and hospitalization (2014-2018) in both groups were analysed. Pooled Standardized Mortality/Hospitalization Ratios (SMRpooled/SHRpooled) were estimated through random-effect meta-regression of individual site SMR/SHR (reference: CS regional rate). The main groups of diseases and those for which the evidence of an association with the residential exposure to P&R and S was defined limited were analysed in adult while only the main groups of diseases were analysed in paediatric-adolescent and juvenile ages subgroups (0-1, 0-19, 20-29 years). All the analyses were performed separately for the two groups of CSs, and by sex.
RESULTS: In the two CSs groups, the overall and the main causes mortality and hospitalization, including all cancers, exceeded in both sexes. Specifically, for lung cancer in the P&R group, among males SMRpooled=1.11 (CI90% 1.00-1.23) and SHRpooled=1.18 (0.99-1.40) and among females SMRpooled=1.13 (1.03-1.25) and SHRpooled=1.20 (1.05-1.38), while in the S group, SMRpooled=1.17 (1.02-1.34) and SHRpooled=1.27 (0.87-1.86) among males and SMRpooled=1.21 (0.93-1.59) and SHRpooled=1.19 (0.91-1.57) among females. The mortality and hospitalization exceeded also for breast cancer in the P&R group. Hospitalization for leukaemia and respiratory diseases increased in the S group. In both CSs groups, among 20-29 years old sub-population, mortality for all tumours and hospitalization for respiratory diseases was worthy of note and hospitalization for all tumours exceeded among 0-1-year age-subgroup.
CONCLUSIONS: The results suggest that living in petrochemical/refineries and steel plants CSs is associated with increased risk for specific diseases. The meta-analytical estimates could contribute to assess the order of magnitude of health impacts of contaminated sites and to perform integrated evaluation of health and environmental impact.
