氯乙烯制品中邻苯二甲酸酯类增塑剂的残留及检测方法

Residues and Analysis Methods of Phthalate Esters Plastificator in Plastics of Vinyl Chloride

简要介绍了各种氯乙烯制品中邻苯二甲酸酯类增塑剂的含量及测定方法,提示邻苯二甲酸酯类增塑剂应用范围广,含量高。对其中可能产生内分泌干扰作用的化学物质种类、毒性进行了介绍。目前已报道的对动物的影响主要是生殖毒性,如输精管萎缩、排卵障碍等。建议尽快进行调查研究和采取预防措施。

Residues and analysis methods of phthalate esters plastificator in various plastics of vinyl chloride are presented,and the wide-use and high environment burden of these chemicals is indicated.The categories and toxicity of phthalate esters that might have the effects of environmental endocrine-disrupting chemicals are introduced.It is shown by the current studies that the effects of these chemicals on laboratory animals were focused on procreation toxicity such as spermaduct atrophy and ovulation clog,etc.It is suggested that more investigation of these chemicalspotential toxicity should be made and preventive measures should be taken promptly.
