Polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) were determined in 24 soil samples collected near a municipal solid waste incinerator (Tarragona, Catalonia, Spain). Soil samples were obtained at various sites within 1.5 km from the stack. Total PCDD/F concentrations ranged from 0.225 to 5.80 ng TEQ/kg dry matter (d.m.) with a median value of 0.799 ng TEQ/kg and a mean value of 1.080 ng TEQ/kg. No remarkable PCDD/F contamination was found. The results were consistent and even lower than those reported in other international studies. Principal Component Analysis and hierarchical cluster analysis were used to compare these soil samples with a set of 10 additional samples collected outside the influence of the plant. Principal Component and hierarchical cluster analyses of soils in the vicinity of the incinerator provide patterns of PCDD/Fs quite similar from those obtained in soils collected far from the influence of that facility.
对在一座城市固体废弃物焚烧厂（位于西班牙加泰罗尼亚自治区塔拉戈纳市）附近采集的24份土壤样本中的多氯代二苯并 - 对 - 二噁英和二苯并呋喃（PCDD/Fs）进行了测定。土壤样本取自距烟囱1.5公里范围内的不同地点。PCDD/Fs的总浓度范围为0.225至5.80纳克毒性当量/千克干物质，中位数为0.799纳克毒性当量/千克，平均值为1.080纳克毒性当量/千克。未发现明显的PCDD/F污染。结果是一致的，甚至低于其他国际研究报告的结果。使用主成分分析和层次聚类分析将这些土壤样本与另外10份在工厂影响范围之外采集的样本进行比较。对焚烧厂附近土壤的主成分分析和层次聚类分析表明，PCDD/Fs的分布模式与在远离该设施影响的土壤中获得的模式非常相似。
