Since the mid-90s, an environmental surveillance program has been on-going to provide information on the levels of PCDD/Fs and various metals in soil and vegetation samples collected in the vicinity of a municipal solid waste incinerator (MSWI) in Tarragona (Catalonia, Spain). However, the presence of other potential sources of pollution in the zone, such as traffic, forest fires, local industries, etc., makes hard to determine the impact concerning the MSWI. Therefore, in 2007 a change in the monitoring program was implemented by collecting additional ambient air samples through active and passive sampling devices. Mean PCDD/F levels in herbage and soil were 0.10 ng I-TEQ/kg dry weight (range: 0.05-0.17 ng I-TEQ/kg dw) and 0.64 ng I-TEQ/kg dw (range: 0.13-2.41 ng I-TEQ/kg dw), respectively. A significant reduction of the PCDD/F concentration in both monitors was observed with respect to our previous surveys. Air mean concentrations of PCDD/Fs were 12.04 and 15.21 fg WHO-TEQ/m(3) in 2007 and 2008, respectively, meaning a non-significant increase of 26%. In addition, a generalized increase of environmental metal levels with respect to our baseline study was not observed. The current concentrations of PCDD/Fs and metals in the vicinity of the MSWI of Tarragona are relatively low in comparison with other areas under the influence of emissions from waste incinerators. This indicates that the environmental impact of the MSWI of Tarragona is not significant. Moreover, the modification of the surveillance program has proven to be successful.
自 20 世纪 90 年代中期以来，一直在进行环境监测计划，以提供在西班牙塔拉戈纳市（加泰罗尼亚）附近的垃圾焚烧厂（MSWI）附近采集的土壤和植被样本中 PCDD/Fs 和各种金属的水平信息。然而，该地区存在其他潜在的污染源，如交通、森林火灾、当地工业等，这使得难以确定与 MSWI 有关的影响。因此，2007 年通过使用主动和被动采样设备收集额外的环境空气样本，对监测计划进行了更改。草本植物和土壤中 PCDD/F 的平均水平分别为 0.10 ng I-TEQ/kg 干重（范围：0.05-0.17 ng I-TEQ/kg dw）和 0.64 ng I-TEQ/kg dw（范围：0.13-2.41 ng I-TEQ/kg dw）。与我们之前的调查相比，两个监测器中的 PCDD/F 浓度均显著降低。2007 年和 2008 年，空气中 PCDD/Fs 的平均浓度分别为 12.04 和 15.21 fg WHO-TEQ/m(3)，这意味着非显著增加了 26%。此外，没有观察到与我们的基线研究相比，环境金属水平普遍增加。与受垃圾焚烧炉排放影响的其他地区相比，塔拉戈纳市附近的 MSWI 附近的 PCDD/Fs 和金属的当前浓度相对较低。这表明塔拉戈纳市 MSWI 的环境影响并不显著。此外，监测计划的修改已被证明是成功的。
