【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。
