The concentrations of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), as well as the levels of a number of heavy metals, have been periodically measured in samples of soil and vegetation collected around a municipal solid waste incinerator (MSWI) in Tarragona (Catalonia, Spain) for approximately 20 years. Since 2007, the levels of the above-mentioned pollutants have also been determined in air samples by means of either active or passive samplers. In the present study, data regarding the environmental impact of the MSWI, in terms of PCDD/Fs and heavy metals, are updated. The temporal trends of these pollutants were evaluated by comparison with data from previous surveys. In the current survey (2013-2014), mean concentrations of PCDD/Fs in soil, vegetation, and air were 0.63 ng I-TEQ/g, 0.07 ng I-TEQ/g, and 10.1 fg WHO-TEQ/m(3), respectively. Decreases of 47 and 35 % of PCDD/Fs in soil and vegetation, respectively, were observed in relation to the background study (1999). Regarding air samples, a slight temporal decrease of the PCDD/F levels was also found with the remaining concentrations staying nearly constant through time. With respect to metals, notable fluctuations in the concentrations were noted, being dependent on each specific environmental monitor. Overall, the current exposure to PCDD/Fs and metals does not mean any additional health risks for the population living near the facility. In conclusion, the results of the present study show that the environmental impact of the Tarragona MSWI is not significant, in terms of PCDD/Fs and heavy metals, after >20 years of continuous operation.
在西班牙加泰罗尼亚塔拉戈纳的一座城市固体废弃物焚烧炉（MSWI）周边，已定期对土壤和植被样本中的多氯代二苯并 - 对 - 二噁英和二苯并呋喃（PCDD/Fs）浓度以及多种重金属含量进行了约20年的测量。自2007年起，还通过主动或被动采样器对空气样本中的上述污染物水平进行了测定。在本研究中，更新了关于MSWI在PCDD/Fs和重金属方面的环境影响数据。通过与先前调查数据进行比较，评估了这些污染物的时间趋势。在当前调查（2013 - 2014年）中，土壤、植被和空气中PCDD/Fs的平均浓度分别为0.63 ng I - TEQ/g、0.07 ng I - TEQ/g和10.1 fg WHO - TEQ/m³。与背景研究（1999年）相比，土壤和植被中PCDD/Fs分别下降了47%和35%。对于空气样本，也发现PCDD/F水平随时间略有下降，其余浓度随时间基本保持恒定。关于金属，浓度出现了显著波动，这取决于每个特定的环境监测点。总体而言，当前接触PCDD/Fs和金属对居住在该设施附近的人群并不意味着有任何额外的健康风险。总之，本研究结果表明，经过20多年的持续运行，塔拉戈纳MSWI在PCDD/Fs和重金属方面对环境的影响并不显著。
