摘要
分别采集了重庆典型岩溶区5条地下河水体10个样品,用气相色谱法对样品中的邻苯二甲酸酯类（PAEs）含量进行测定,分析其在重庆典型岩溶区地下河水体中的分布特征。结果表明,常见的19种邻苯二甲酸酯类（PAEs）在重庆典型岩溶区地下河水体中均有检出,其浓度范围为103.29-2268.78μg/L;5种被美国环保局列为优先控制的PAEs类污染物中,邻苯二甲酸二丁酯（DBP）和邻苯二甲酸双（2-乙基己基）酯是主要的污染物;与国内外其他地区水体进行比较,重庆典型岩溶区地下河水体PAEs含量处于较高污染水平。
Samples of underground river were collecterd at 10 sites in Chongqing typical karst areas.Phthlic acid esters（PAEs） concentrations in each sample were determined by Gas chromatography.The results were shown as follows：19 kinds of PAEs were detected in underground rivers of Chongqing typical karst areas,the concentration of PAEs is 103.29～2268.78μg/L;Di-n-butyl phthalate（DBP） and di-（2ethylhexyl） phthalate（DEHP） are the main pollutants in the 5 kinds of PAEs pollutants priority controlled by EPA;Compared with other rivers in the world,the concentration of PAEs in underground rivers of Chongqing typical karst areas is in the high level.
