Levels of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) were determined in twenty-one ambient air samples, eight soil samples and two stack gas samples, collected near or in a municipal solid waste incinerator (MSWI) in Hsinchu, Taiwan. A systematic decrease of PCDD/Fs in the ambient air from the northeastern area was observed. PCDD/Fs levels measured in the ambient air range from 0.058 to 0.127 pg-TEQ/m3. Higher PCDD/Fs levels in the ambient air were found during winter. In addition, PCDD/Fs levels measured in the soil range from 0.524 to 5.02 pg-TEQ/g d.m. Principal component analysis (PCA) and hierarchical cluster analysis (HCA) did not provide sufficient evidence that the environmental PCDD/Fs contamination was caused by emissions from the Hsinchu MSWI. An unknown PCDD/Fs source was proposed using congener profile analysis and supported by both PCA and HCA.
对台湾新竹市一座城市固体废弃物焚烧厂（MSWI）附近或厂内采集的21份环境空气样本、8份土壤样本和2份烟道气样本中的多氯二苯并对二噁英和二苯并呋喃（PCDD/Fs）水平进行了测定。观察到来自东北地区的环境空气中PCDD/Fs呈系统性下降。环境空气中测得的PCDD/Fs水平在0.058至0.127 pg-TEQ/m³之间。冬季环境空气中的PCDD/Fs水平较高。此外，土壤中测得的PCDD/Fs水平在0.524至5.02 pg-TEQ/g干物质之间。主成分分析（PCA）和层次聚类分析（HCA）未提供足够证据表明新竹MSWI的排放导致了环境PCDD/Fs污染。通过同源物谱分析提出了一个未知的PCDD/Fs来源，并得到了PCA和HCA的支持。
