| 摘要: |
| 对浙江某电子垃圾回收地水体、沉积物、土壤以及大气中得克隆（ＤＰ）的污染水平及分布特征进行了调查。结果表明，水、沉积物、土壤和大气样品中均检测出了ＤＰ，分别为０．８４３～１．５６ｎｇ／Ｌ，０．１８５～７．０３ｎｇ／ｇ干重，０．１１５～２６．４ｎｇ／ｇ干重和１１．２ｐｇ／ｍ３；该区域ＤＰ分布特征表明电子垃圾的拆解和焚烧是环境中ＤＰ的重要来源。 |

| Abstract: |
| Dechlorane Plus (DP),a new chlorinated flame retardant, has been widely used in electronic products. In this research, the levels and spatial distribution of DP in water, sediment, soil and atmosphere from an electronic waste (e-waste) recycling site in Zhejiang Province were investigated. The results showed that DP were detected in all samples. The concentrations of DP in water, sediment, soil and atmosphere ranged from 0.843 to 1.56 ng/L,0.185 to 7.03 ng/g dry weight(dw),0.115 to 26.4ng/g dw and 11.2 pg/m3, respectively. The spatial distribution of DP supported that e-waste dismantling and burning process was the important source of DP. |
