Occurrence and Composition Profiles of Several Environmental Endocrine Disruptors in Food Packaging Material from South China

Hong Wu, Lulu Jia, Xianqi Feng, Yi Li, Shuangyue Sun

Abstract


Phthalates, parabens, bisphenols, benzophenones and triclosan (TCS) are ubiquitous in environment, known as environmental endocrine disruptors (EEDs). In this study, those EEDs were analyzed in food packaging materials (n=96) collected from local markets in Guangzhou, South China. Nineteen of 30 target compounds were detected in > 90% samples, and for the fi rst time, TCS (~ 100%) and benzophenones (~50%-100%) were found ubiquitous in food packaging materials. For all samples, concentrations of phthalate were the highest (median: 12100 ng/g), usually thousands of times other EEDs, and were signifi cantly higher in aluminum plastic than those in paper and plastics (p < 0.01). The median concentration of TCS was 9.62, 7.51 and 6.31 ng/g in the paper, plastic and aluminum plastic packaging material samples, respectively, but no diff erence was observed among three categories. No correlation was found between concentrations of phthalates and other EEDs, indicating its special source diff erent from others.
