Long-term health effects of a third-generation waste-to-energy plant: the experience of Turin (Italy).

Abstract

The long-term study on adverse health effects of the third-generation waste-to-energy (WTE) plant located in Turin, Italy, is part of a broader health surveillance system. We considered 369 236 subjects living in areas with different levels of emission fallout, as well as a control group, from 1 January 2014, until the end of the follow-up period. Hospital admissions for cardiac diseases (ICD-IX: 390-429), ischaemic heart diseases (ICD IX: 410-414), chronic heart failure (ICD IX: 428.0, 428.2, 428.9), cerebrovascular diseases (ICD IX: 430-438), acute respiratory diseases (ICD IX: 460-466, 480-487), and COPD (ICD IX: 490-492, 494, 496) were evaluated for the population considered. Cox models were used, considering individual characteristics and overall environmental exposure. We also considered all births (n = 8296) of women residing in the area at the time of delivery during the study period. Log-binomial models were run separately for each outcome (sex ratio, multiple births, preterm births, on term low birthweight and small for gestational age births), adjusting for exposure to other pollution sources and maternal characteristics. Miscarriages were evaluated using hospital admissions registries. No relationship was found for the outcomes considered in the wider area, neither with hospital admissions nor with adverse reproductive outcomes. There is an association with chronic heart failure and ischaemic heart diseases in the maximum exposure area, but the small number of events suggests caution in interpreting this result. This study confirm results of other health surveillance lines, showing no evident harmful effects of the WTE plant.
