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 of 16congeners of PAEs ranged from 2.705 to 13.779μg/g, with an average of 5.477μg/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, representing 73.5% 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 than 1.0, 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.
