摘　　要：为了解我国市售卫生巾中邻苯二甲酸酯污染特征,采集了16种常见品牌的卫生巾样品,采用气质联用仪(GC-MS)对其中16种PAEs进行测定分析,并应用美国环境保护署(USEPA)推荐的方法评估了其健康风险.结果表明,我国市售卫生巾样品中∑_(16)PAEs含量为2.705~13.779μg/g,平均为5.477μg/g,较婴儿纸尿裤等产品污染水平略高;DIBP、DBP和DEHP是含量最高的三种单体,三者占PAEs总含量的73.5%,可能与卫生巾原料和加工过程的人为添加有关;卫生巾中DMP、DEP、DIBP、DBP、BBP、DEHP和∑_6PAEs非致癌风险值远小于1,对人体无明显非致癌风险,但DEHP可能对人体存在一定的致癌风险,应引起重视.Sixteen kinds of phthalate esters(PAEs)in sanitary napkins of sixteen different brands were detected using gas chromatograph-mass spectrometer(GC-MS)to improve our understanding of the contamination of PAEs in the marketed products in China.Further,the health risk of PAEs in sanitary napkins was assessed based on the method recommended by United States Environmental Protection Agency(USEPA).The results showed that the concentrations of16congeners of PAEs ranged from2.705to13.779μg/g,with an average of5.477μg/g,which were slightly higher than the PAE concentrations in the baby diapers observed in the previous study.Di-iso-butyl phthalate(DIBP),di-n-butyl phthalate(DBP)and di-(2-ethylhexyl)phthalate(DEHP)were the dominant congener in all samples,representing73.5%of the total PAEs.Pollution of the three congeners may be related to the using of raw materials and additives consisting of,containing or contaminated with PAEs.The hazard quotients of dimethyl phthalate(DMP),diethyl phthalate(DEP),DIBP,DBP,butyl benzyl phthalate(BBP),DEHP and total PAEs were far less than1.0,respectively,indicating that the non-carcinogenic levels from exposure to PAEs in sanitary napkins were acceptable.However,the carcinogenic risks from exposure to DEHP in sanitary napkins exceeded the acceptable level,which should be of concern.
