2005年，毕尔巴鄂（西班牙巴斯克地区）启用了一座城市固体废物焚烧炉（SWI）。2006年和2008年分别从95名和107名志愿者中收集了血清和尿液样本，其中62份来自同一个体。测定血铅水平（BPb），以及尿镉（Cd）、铬（Cr）和汞（Hg）浓度（UCd、UCr和UHg）。Alonsotegi镇和毕尔巴鄂自治市（阿尔塔米拉，Rekalde）被认为距离工厂不到2 km，并且对应于高交通密度的城市环境。参考区域为毕尔巴鄂自治市（Santutxu-Barbaran），距离电厂5 km，也是一个交通密度高的市区，以及一个工业活动少、交通密度低的小镇（Balmaseda），距离电厂20 km;就盛行风而言，这两个区域均不在现场的下风处。BPb具有显著相关性，r=0.63（p 0.05）。多元线性回归模型并没有显示随着时间的推移，在靠近SWI的地区的BPb，UCd，UCr和UHg的水平的增加相比，位于更远的地区，调整混杂变量后。这些结果加强了这一假设，即现代工厂附近的固体废物焚烧人口不表现出增加的重金属水平。(c)2010爱思唯尔有限公司版权所有。
In 2005 an urban solid waste incinerator (SWI) was commissioned in Bilbao (Basque Country, Spain). Serum and urine samples were collected from 95 and 107 volunteers in 2006 and 2008 respectively, of which 62 were repeats from the same individuals. Blood lead levels (BPb) were determined, as were the concentrations of cadmium (Cd), chromium (Cr) and mercury (Hg) in urine (UCd, UCr and UHg). The town of Alonsotegi and a borough of Bilbao (Altamira, Rekalde) were considered to be close, less than 2 km from the plant, and correspond to an urban environment with high traffic density. The areas of reference were a borough of Bilbao (Santutxu-Zurbaran), 5 km from the plant, also in an urban area with high traffic density, and a small town with little industrial activity and low traffic density (Balmaseda) 20 km from the plant; neither of these is downwind from the site with respect to prevailing winds. There was a significant correlation for BPb, r=0.63 (p0.05). Multiple linear regression models did not show increases over time of the levels of BPb, UCd, UCr and UHg in the areas close to the SWI compared to those of areas located further away, after adjusting for confounding variables. These results reinforce the hypothesis that populations near modern plants for solid waste incineration do not manifest increased levels of heavy metals. (c) 2010 Elsevier B.V. All rights reserved.
