The increasing output of OPFRs and the increasing detection of OPFRs in environmental media have attracted wide attention of scholars at home and abroad. OPFRs are generally semi-volatile, easy to enter the environment and accumulate in organisms,causing potential hazards to the environment and human health. In this paper, the pollution status and toxic effects of OPFRs in aquatic environment were introduced,and the research progress of human health risk caused by them was summarized.The existing problems were pointed out, and the future research was prospected. In the future, the analytical methods of various environmental and biological media should be improved, and comprehensive and in-depth environmental investigation and ecological and health risk assessment should be carried out. Attention should be paid to the effects of combined pollution on organisms and the study of biological acceptability.展开更多
文摘目的建立高效液相色谱法(high performance liquid chromatography,HPLC)测定罗非鱼中氯霉素残留量。方法样品采用乙酸乙酯为溶剂提取,无水硫酸钠脱水,提取液氮气吹干,以10%甲醇溶液溶解,冷冻除去脂肪,经C18固相萃取小柱净化,采用C18固相萃取柱分离,流动相甲醇-水,梯度洗脱,流速为1 m L/min,紫外检测波长280 nm。结果在0.1~5μg/m L范围内,氯霉素浓度和峰面积线性关系良好,精密度较好,相对标准偏差(relative standard deviation,RSD)在3.12%~7.53%之间,检测限为0.02μg/g,回收率80.5%~107.1%。结论该方法前处理方法简单、快捷,对实验员身体危害小,准确度较好,适用于罗非鱼中氯霉素含量的测定。
