There is a great concern in the Basque Country regarding emissions from waste incineration, in particular that of organochlorines (OCs), including dioxins, furans and polychlorinated biphenyls (PCBs), and their potential effect on human health. In 2005, a municipal solid waste plant (MSWP) started to operate in Bilbao, representing an opportunity to assess the exposure to the aforementioned pollutants among people living at various distances from the plant. In 2006 and 2008, we carried out two cross-sectional studies to quantify and assess changes in levels of these pollutants. The objective of this study was to describe the levels of OCs in the blood serum in 2013 of 127 adults of this prospective cohort, in four centres of population, near to and further away from the MSWP, and to study trends over time since it started to operate. This study shows the levels of OCs have decreased significantly, from 37.2% to 80.1%. Further, levels of OCs in areas near to the MSWP were not found to be higher than those in areas further afield.
巴斯克地区对垃圾焚烧产生的排放物，尤其是有机氯（OCs），包括二噁英、呋喃和多氯联苯（PCBs）及其对人体健康的潜在影响极为关注。2005年，一座城市固体废物处理厂（MSWP）在毕尔巴鄂开始运营，这为评估居住在距该厂不同距离的人群接触上述污染物的情况提供了契机。在2006年和2008年，我们开展了两项横断面研究，以量化和评估这些污染物水平的变化。本研究的目的是描述该前瞻性队列中127名成年人在2013年时血清中有机氯的水平，这些成年人分布在四个靠近和远离城市固体废物处理厂的人口中心，并研究自该厂开始运营以来随时间的变化趋势。本研究表明，有机氯水平已显著下降，降幅从37.2%至80.1%。此外，未发现靠近城市固体废物处理厂地区的有机氯水平高于更远地区的水平。
