title: [Analysis of phthalates in aromatic and deodorant aerosol products and evaluation of exposure risk].
abstract: We established an analytical method for the detection of seven phthalates, dimethyl phthalate, diethyl phthalate (DEP), benzyl butyl phthalate, di-i-butyl phthalate, dibutyl phthalate (DBP), diethylhexyl phthalate (DEHP), and di-n-octhyl phthalate, using an ultra high performance liquid chromatograph equipped with a photodiode array detector. This method is quick, with minimal contamination, and was applied to the analysis of aromatic and deodorant aerosol products. Phthalates were detected in 15 of 52 samples purchased from 1999 to 2012 in Yokohama. Three types of phthalate (DEP, DBP, DEHP) were detected, and their concentrations ranged from 0.0085-0.23% DEP in nine samples, 0.012-0.045% DBP in four samples, and 0.012-0.033% DEHP in four samples. No other phthalate esters were detected. Furthermore, we estimated phthalate exposure via breathing in commonly used aromatic and deodorant aerosol products, then evaluated the associated risk. The estimated levels of phthalate exposure were lower than the tolerated daily limit, but the results indicated that aromatic and deodorant aerosol products could be a significant source of phthalate exposure.
