摘要

Phthalate esters were categorized as the suspected environmental hormone because of their endocrinedisrupting effects. The contents of phthalate esters in commercial foods and phthalate esters released from the packaging materials and containers under the optimal releasing conditions were investigated in this study. The detection limit for di-methyl phthalate (DMP), di-n-butyl phthalate (DBP), di-(2-ethylhexyl) phthalate (DEHP) and di-n-octyl phthalate (DOP) was 0.10 ppm, 0.05 ppm, 0.03 ppm and 0.12 ppm, respectively. The results showed that DOP was not detected in all samples and DMP was only found in one dairy product. The contents of DBP in rice wine, tea, fruit juice, carbonated drink, dairy products and vegetable oil were 2.3-90 ppb, 1.7-4.4 ppb, 0.6-1.6 ppb, 0.6-0.8 ppb, 7.9-11.1 ppb and 48.1-134 ppb, respectively. The contents of DEHP in rice wine, tea, fruit juice, carbonated drink, dairy products and vegetable oil were 3.4-11.8 ppb, 2.0-4.8 ppb, 1.2-20.1 ppb, 1.8-6.1 ppb, 80-100 ppb and 835-2387 ppb, respectively. The quantity of phthalate esters released from PE, PP, PS, PET, PVC and PVDC with the optimal releasing conditions were analyzed. Results showed that both DMP and DOP were not detected in all samples. The highest content of DBP released was PVDC (2.0-36.5 ppb), and the order of the content of each DBP released was PE＞PP＞PS＞PVC＞PET. In addition, the highest content of DEHP released was PP (9.5-21.5 ppb), and the order of the content of each DEHP released was PE＞PET＞PS＞PVC＞PVDC.
