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0.665~102 ng·g-1 干重,河流表层沉积物和水中DP的浓度范围分别为0.165~65.1 ng·g-1 干重和ND?4.91 ng·L-1.生产厂污水处理池的活性污泥中DP的浓度为1.23×104 ng·g-1 干重,污水池出水中DP的浓度高达2.29×104 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.
Abstract:
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 0.665-102 ng·g-1 dry weight.The concentration ranges of DP in the surface sediments and water from the surrounding river were 0.165-65.1 ng·g-1 dry weight and ND?4.91 ng·L-1,respectively.The concentrations of DP in the activated sludge and the effluent water from the wastewater treatment pool were 1.23×104 ng·g-1 dry weight and 2.29×104 ng·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.
