农药厂周边有机磷农药在生物体中残留的检测方法研究

摘要:
测定南京某农药厂附近大米、蔬菜及肉类中11种有机磷农药含量,通过使用气相色谱/质谱联用的方法,建立GC/MS定性定量分析方法,检出限达到0.05 μg/kg(肉类)和0.1 μg/kg(大米和蔬菜),回收率均符合测定要求。环境样品监测结果显示,大米和蔬菜中有机磷农药的含量高于肉类中的含量,说明在大米和蔬菜表面残留的农药量要高于进入生物体体内的含量。南京蔬菜样品中有机磷农药高于常州蔬菜样品,说明农药厂对蔬菜表面残留农药量有影响。不同的有机磷农药在不同的介质中,检出情况不一样,说明不同的环境介质对有机磷农药的保留水平不一样。

Study on the Concentration of Organophosphorus Pesticides in Different Environment Media from an Insecticide Factory

Abstract:
The study detected 11 organophosphorus pesticides in three environment medias:rice, vegetables and meat. We detected the concentration of different organophosphorus pesticides with GC/MS. The detection limit of meat and rice & vegetables were 0.05 μg/kg and 0.1 μg/kg respectively. Recovery results all met measurement requirements. The result showed that the total concentration of 11 organophosphorus pesticides were higher in rice and vegetables than meat revealing that the amount of pesticide residues in rice and vegetable surface were higher than that inside living organisms. Samples collected form Nanjing was with higher concentration than Changzhou. Organophosphorus pesticides in different environmental medias showed a different detection rate revealing that various environmental media have different impact on the content of pesticide residues.
