邻苯二甲酸酯类化合物(PAEs)属于芳香族二羧酸酯,多为高沸点、低蒸气压液体,对塑料的稳定性起着重要作用,广泛用作多种塑料膜的增塑剂,特别用于纤维素与乙烯树脂,以增加其韧性和柔性。鉴于食品包装的需要,其中许多已做过急性毒性及慢性饲养试验,其毒性均较低 1978年美国国际商业局公布的PAEs产量约为200万吨。1987～1989年我国平均年产量约为18万 Phthalates (PAEs) are aromatic dicarboxylic esters, mostly high boiling point, low vapor pressure liquid, plays an important role in the stability of plastics, widely used as a plasticizer for a variety of plastic films, Especially for cellulose and vinyl, to increase its toughness and flexibility. Due to the need for food packaging, many of them have been tested for acute toxicity and chronic feeding, with low toxicity. The U.S. Bureau of International Commerce published about 2 million tons of PAEs in 1978. From 1987 to 1989, China’s average annual output was about 180,000
