摘要:多溴联苯醚(PBDEs)是一种新型的持久性有机污染物(POPs)。采用固相萃取-气相色谱法测定了某塑料企业周边及当地自然水体中的PBDEs浓度，主要针对BDE-17、28、47、66、85、99、100、138、153、154、183、203及BDE-209共13个PBDE同系物的浓度水平、组成分布和污染特征进行分析。结果显示，使用企业周边水体中除BDE-203在水体中未检出外，其余12种PBDE同系物均有不同程度的检出。Σ13PBDEs质量范围处于未检出～363 ng·L^-1,各同系物的平均质量浓度为未检出～42.6 ng·L^-1。其中BDE-209为最大检出质量丰度同系物，但其检出率仅为25.0%，检出率较高的同系物是BDE-17、BDE-28和BDE-100，检出率分别为75.0%、75.0%、58.3%，低溴代联苯醚的检出率显著高于高溴代联苯醚。当地自然水体中13种PBDEs均有不同程度的检出，检出浓度在0.161～1.83 ng·L^-1。企业周边水体中PBDEs的污染水平显著高于自然水体，是自然水体浓度的5～100倍。因此，企业周边区域水体中PBDEs的污染情况应引起相关部门关注。

Abstract:Polybrominated diphenyl ethers (PBDEs) is a new kind of persistent organic pollutants (POPs). Concentrations of 13 kinds of PBDE congeners (BDE-17, 28, 47, 66, 85, 99, 100, 138, 153, 154, 183, 203, 209) in water surrounding a typical plastic production site and natural water in South Jiangsu were determined with the solid phase extraction (SPE) - gas chromatography (GC) method, to study concentration level, composition distribution and pollution characteristics of the pollutants in the area. Results show that the PBDEs could be all detected except BDE-203. The total concentration range of Σ13PBDEs was not detected (ND)~363 ng·L^-1, and average mass concentration of each homologue was ND~42.6 ng·L^-1. BDE-209 was the homologue with the largest mass abundance, but its detection rate was only 25.0%. The detection rate of BDE-17, BDE-28 and BDE-100 was higher, i.e., 75.0%, 75.0% and 58.3% respectively. The detection rate of low bromine generation diphenyl ether was significantly higher than high bromine generation diphenyl ether. The 13 kinds of PBDEs could be all detected in nature water, and the concentration range of PBDEs was 0.161~1.83 ng·L^-1. The concentration levels of PBDEs in water surrounding enterprise was 5-100 times higher than the natural water, which should be paid more attention regarding to PBDEs pollution in water surrounding typical enterprise.
