以酶联免疫分析(EIA)方法筛选和同位素稀释、高分辨气相色谱、高分辨质谱联用(HRGC-HRMS)技术确认相结合的方式,对上海地区土壤二(口恶)英水平进行了研究.以w(二(口恶)英)的区域筛选值19.0 ng/kg(以EIA-TEQ计)作为筛选标准,以文献上限值10.0 ng/kg作为确认标准,对超过筛选标准的样品进行确认,并对高于确认标准的样品进行了化学组分分析.共筛选了包括农业土壤、林地、绿地在内的145个样品,其中高于筛选标准的样品有7个,经HRGC-HRMS确认后有3个样品高于确认标准,其w(二(口恶)英)为10.2～61.2 ng/kg(以I-TEQ计).这些样品来自工业区和垃圾焚烧厂周围.组成模式分析结果显示,它们可能受到焚烧输入源的...

A combined strategy of screening with enzyme-linked immunoassay, isotope dilution method and the HRGC-HRMS confirmatory method was used to investigate polychlorinated dibenzo-p-dioxins and dibenzofurans of soil in Shanghai. Because no guideline of dioxin in soil is available in China yet, the regional screeing value 19.0 ng （EIA-TEQ）/kg was used as the screening bound, while 10.0 ng （TEQ）/kg was used as the confirming bound, which is the maximum value of the background upper value coming from available literature. The samples over the scree...
