Abstract:
Objective To investigate the pollution of phthalate ester in indoor environment. Methods Settled dust samples from 10 households, 10 offices and 10 student dormitories in Beijing were collected. Seven kinds of phthalate esters in these samples were determined with solid phase extraction-high performance liquid chromatography (SPE-HPLC) .Dates were analyzed statistically by nonparametric tests. Results The main phthalate esters in dust were di (2-ethylhexyl) phthalate (DEHP), dibutyl phthalate (DBP) and dicyclohexyl phthalate (DCHP). Of phthalate esters, DEHP with the range of 28-6 073 mg/kg had the highest concentration in indoor dust. The total level of phthalate esters in households was the highest, offices followed, student dormitories was the last. The Kurskal-Wallis H test showed that the concentrations of BBP, DEHP and DCHP in dust were significantly different in 3 types of rooms (P
