邻苯二甲酸酯的毒性及其降解研究

Toxicity of Phthalic Acid Esters and Research of Degradation

利用啮齿动物对邻苯二甲酸酯(PAEs)的"三致"性及内分泌干扰性进行研究,并对利用水生生物对DMP、DEP、DAP、DBP、DIBP、BBP这6种邻苯二甲酸酯进行实验,发现较高分子量的邻苯二甲酸酯对水生生物不产生急性或慢性毒性,而较低分子量的邻苯二甲酸酯的毒性随烷基链的长度增加而增加。对邻苯二甲酸酯目前常用的微生物降解、真菌降解、声化学降解、光催化降解等途径进行研究,进行了总结和评述,指出其优势及问题,并对未来的发展方向做出展望。。

Rodents and aquatic organisms are used to research for the toxicity of Phthalic Acid Esters(PAEs). As to aquatic organisms, there are six Phthalic Acid Esters(DMP, DEP, DAP, DBP, DIBP, BBP) in the experiment,and it found out that the higher molecular weight of Phthalic Acid Esters do not produce acute or chronic toxicity to aquatic organisms, and low molecular weight on the toxicity of Phthalic Acid Esters do. The common methods of degradation of Phthalic Acid Esters at present is Microbial degradation, Fungal biodegradation, Sonochemical degradation and Photocatalytic degradation. It summarized and points out its advantages and problems. Finally, it has made expectation for the future development direction.
