报告题目:Phthalate Contamination in Cooking Oil and the Indoor Environment Dust (邻苯二甲酯在食用油和室内尘土中的污染)

报告时间:2015年5月26日(周二)10:00

报告内容简介: Phthalates are o-phthalic acid esters, which are widely used as plasticizers in plastic materials and solvents in some cosmetic products. Due to adverse effects on human health, the occurrence of phthalates in food and the indoor environment has gained increasingly attention. In this study, 21 cooking oil samples and 44 floor dust samples from different indoor environments in Delaware, USA were collected and analyzed for 14 phthalates using gas chromatography-mass spectrometry. All oil samples were found to contain detectable phthalates and tThe content of total plasticizers in oil samples was determined to be 210~7558 μg/kg. Phthalates were detected in all dust samples with the total concentration ranging from 84 to 7117 mg kg-1. DEHP (di-2-ethylhexyl phthalate), BzBP (benzylbutyl phthalate), DBP (dibutyl phthalate), and DiBP (di-isobutyl phthalate) were both the most frequently and abundantly detected phthalates. The average concentration of total phthalates in dust from offices, student dorms, gyms, stores, and daycare centers was found to be significantly or insignificantly (p = 0.05) higher than that in dust from houses and apartments.

报告题目:Sources, Toxicity, and Contamination of Bisphenols in Food and the Environment (双酚类化合物的来源、毒性及其在食品和环境中的污染)

报告时间:2015年5月27日(周三) 16:00

报告地点:翠十教203

报告内容简介:Bisphenol A and its alternatives are used as monomers for the synthesis of polycarbonate plastics and epoxy resin. With the wide application of these polymer materials, bisphenols have become ubiquitous in the environment, thus raised great concerns on human health. In this talk, the sources and toxicity of bisphenol A and its alternatives were introduced. The presence of bisphenols in various food samples and the indoor environment dust from different countries was summarized, compared, and assessed. Canned food was found to contained higher bisphenol A and total bispehnols than that in other types of packaging. Bispehnol A, S, and F were found to be the dominating bisphenols in dust samples.  Remaining questions and challenges in bisphenol environmental research were also discussed.
