养殖鱼邻苯二甲酸酯的含量分析

目的：为了解宁波地区淡水养殖鱼PAEs污染情况。方法采用液液超声萃取-气质联用法对宁波6个不同养殖点5种淡水养殖鱼体内8种邻苯二甲酸酯含量进行分析。结果宁波地区养殖鱼主要受 DMP、 DEP、 DBP、 DEHP 和 DOP 污染，质量分数最高可达134.1、258.9、249.2、830.8和5029μg/kg；草鱼、鳊鱼、鳙鱼、鲫鱼和乌鳢邻苯二甲酸污染指数PPI分别为9.999、9.735、13.97、8.945和5.809μg/kg。结论宁波地区淡水养殖鱼鱼体邻苯二甲酸酯含量与养殖环境有关，与鱼种无关。

Analysis of Phthalic Acid Esters in Muscles Tissue of Cultured Fishes

Objective The detection and quantification of eight phthalate esters -dimethyl phthalate （ DMP） , diethyl phthalate （ DEP ） , dibutyl phthalate （ DBP ） , diethylhexyl phthalate （ DEHP ） , diisopropyl phthalate （DIPP）, dipropyl phthalate （DPP）, butyl benzyl phthalate （BBP）, and dioctyl phthalate （ DOP） in the muscle tissues of cultured fishes in six fishponds of ningbo were carried out using liquid -liquid ultrasonic extraction -gas chromatography -mass spectrometry.Results The result showed that DIPP , DPP and BBP were not detected in the samples , and the highest concentration of DMP, DEP, DBP, DEHP and DOP in the fish species were 134.1, 258.9, 249.2, 830.8 and 5 029μg/kg.The phthalate pollution index （PPI） of Grass carp, bream, carp, crucian carp and black flower were 9.999, 9.735, 13.97, 8.945 and 5.809 μg/kg.Conclusions Double -factorial analysis of variance indicated that the differences in fish phthalate levels were not statistically significant at P ＆lt;0.05 , but the culture environment was significant .
