US scientists find evidence of highly toxic ‘super-phthalate’ in plastics

18-Feb-2011

New research has indicated that a relatively unknown phthalate called dipentyl phthalate (DPeP) may be up to eight times more potent than DEHP. Previous studies have identified DEHP as one of the most toxic varieties of phthalates but the effects of DPeP, also added to plastics in consumer products, are less well known.

However, a recent study by scientists from the US Environmental Protection Agency (EPA) has shown that prebirth exposure to DPeP in rats interferes with testosterone production and reproductive development in male offspring at low levels. Comparison to data previously obtained for exposure to DEHP indicated that DPeP is approximately 8 times more potent in reducing foetal testosterone production and 2-3 times more potent in inducing development of male reproductive malformations. Data from this research, published in Toxicological Sciences, will be valuable for regulatory agencies such as the EPA in undertaking risk assessments of DPeP.

如果证据确凿,那“超级邻苯二甲酸酯”就会被禁止了

DPeP好像我们国内还很少用到工艺上。
作用和DEHP一样吗?

是的,也是用作增塑剂的用途添加到塑料中。我有接触过一些客户要求测试16项邻苯二甲酸酯的,其中就包括邻苯二甲酸二戊酯DPeP.

现在的限值太多,只能是钻一个空子是一个空子了。

常见的六种测得比较多,就添加其他类的来。。

邻苯是很麻烦的
开始是3P
后来6P
再后来7p
再后来16p
再后来。。。

由于国家尚无土壤和食品中酞酸酯的限制规定,因此检测和管理得不到应有的重视。
