RESUMO
Objective To understand phthalic acid esters pollution of daily consumed food in Guangzhou City，and evaluate the hazard of phthalic acid esters exposure in residents dietary. Methods Detected the content of phthalic acid esters in 10 types of food by gas chromatography-mass spectroscopy（GC-MS）methods .It combined with a survey on dietary nutrients intake of Guangzhou residents was conducted．Hazard index on the dietary exposure assessment of chemicals in food was applied. Results It showed that the highest levels of DBP，DEHP and DIBP，from the mixed diet samples in Guangzhou were 1.256，1.418，0.576 mg/kg respectively；and the exposure level of DBP，DEHP and DIBP were 2.431、5.981、2.408μg/kg.d ;HQ was respectively 0.243、0.125、0.025. HI was 0.393. Conclusion The dietary contamination of phthalic acid esters for Guangzhou was kept at a low level.But the pollution of 3 kinds of mixed samples such as meats，eggs，aquatic and products may be a certain risk of health that should attract more attention.
