Phthalates have been associated with reproductive toxicity and precocious puberty in females, but the occurrence of these toxicants in feminine hygiene products is rarely reported. In this study, eight phthalates were determined in 120 feminine hygiene products (56 feminine care products and 64 sanitary napkins) collected from China. Phthalates were found in 86% and 98% of feminine care products and sanitary napkins, respectively, with the total concentrations varying between not detectable and 813µg/g (median: 0.26 µg/g) and 0.25 and 8.76 μg/g (1.43 μg/g), respectively. Diethyl phthalate, dibutyl phthalate and bis(2-ethylhexyl)phthalate were the major compounds, accounting for>60% of the total concentrations. The plastic materials used on the top and bottom layers, as well as the hot melt adhesive used during the manufacturing process, are the potential sources of phthalates in sanitary napkins. The range of daily exposure doses of phthalates in women from the use of feminine care products and sanitary napkins were<0.001 to 0.156μg/kg-bw/day and<0.001 to 0.731μg/kg-bw/day, respectively. Sanitary napkins contributed to 8.2% of the total exposure, and the levels of exposure to several phthalates from sanitary napkins were much higher than those reported from indoor dust ingestion but were lower than those of dietary intakes. Our study confirmed a new source of women's exposure to phthalates, sanitary napkins.
