摘　　要：目的调查重庆市包装饮用水中17种邻苯二甲酸酯(PAEs)的污染情况,为评估其安全性提供基础数据。方法采集重庆市大型超市销售的各种品牌瓶装水44份及重庆本地产桶装水33份,共计77份样品,应用GC/MS同位素内标法对其中17种PAEs含量进行监测,同时对23个瓶装水进行耐热(40℃)存放15 d对DEP和DBEP的影响进行比较。结果 77份检品中,检出DEP、DIBP、DBP、DBEP、DNP,其中DEP和DBEP的检出率分别为58.4%和44.2%,DBEP检出的最大值为34.7μg/L。结论重庆市售包装饮用水中17种PAEs除DBEP外,其余16种PAEs的含量水平均较低,不同水质、不同包装之间无统计学差异。Objective The aim of this study was to survey the pollution status of 17 phthalates in packed drinking water in Chongqing, in order to provide the basic data for evaluating the safety of the packed drinking water. Methods 77 water samples including 44 bottled water samples of various brands and 33 local barreled waters in Chongqing were collected. The contents of 17 phthalates were detected by isotope internal standard gas chromatograph/mass spectrometry（GC/MS）. The contents of DEP and DBEP in 23 bottled water samples before and after they were stored at 40℃ for 15 days were detected and compared. Results DEP, DIBP, DBP, DBEP and DNP were detected respectively from the 77 samples. The detected rates of DEP and DBEP were 58.4% and 44.2%, respectively. The highest content of DBEP was 34.7 μg/L. Conclusion All the kinds of PAEs were at lower levels except for DBEP. There were not significant difference between the different samples of water quality and packages.
