摘　　要：得克隆(DP)是目前正在生产和使用的氯代阻燃剂,调查了DP生产厂周边环境中DP的污染水平及分布特征.生产厂周边表层土壤中DP的浓度范围为0.665~102ng·g^(-1)干重,河流表层沉积物和水中DP的浓度范围分别为0.165~65.1ng·g^(-1)干重和ND-4.91ng·L^(-1).生产厂污水处理池的活性污泥中DP的浓度为1.23×10~4 ng·g^(-1)干重,污水池出水中DP的浓度高达2.29×10~4 ng·L^(-1).水体、沉积物中DP发生了syn-DP选择性富集或anti-DP选择性降解.分析结果表明DP生产厂是周边环境中DP污染的重要来源.Dechlorane Plus（DP）is currently being used in the production and use of chlorinated flame retardants.This study established a method for analysis of DP in samples of soil,sediment and water.The method was used to survey the DP levels and distribution surrounding a DP manufacturing plant in Jiangsu Anbang electrochemical company.The concentration ranges of DP in the surface soil surrounding the plant was 0.665-102ng·g-1 dry weight.The concentration ranges of DP in the surface sediments and water from the surrounding river were 0.165-65.1ng·g-1dry weight and ND-4.91ng·L-1,respectively.The concentrations of DP in the activated sludge and the effluent water from the wastewater treatment pool were 1.23×104ng·g-1 dry weight and 2.29×104ng·L-1,respectively.The results of DP isomer ratios implied that syn-DP selective enrichment or anti-DP selective degradation of DP in water and sediment.It is suggested that the DP manufacturing plant is an important source of DP contamination in the surrounding environment.
