蔬菜中有机磷农药残留量的检测与分析
摘要
有机磷农药作为一类高效、广谱的杀虫剂正被广泛地用于农业防害以及家庭、仓储等的杀虫,但大量使用后产生的环境危害也日益严重。农药的急性中毒,特别是果蔬食品污染后引发的群体中毒事件屡有发生。因此建立果蔬有机磷残留检测技术是很有必要的。
本课题采用乙腈浸提,同时对茄果类、瓜类、甘蓝类、白菜类、绿叶类、豆类6类蔬菜共24个品种,采用气相色谱法检测有机磷中高毒农药甲胺磷、氧化乐果、甲拌磷、对硫磷、甲基对硫磷、毒死蜱、敌敌畏、乙酰甲胺磷、三唑磷、杀螟硫磷、水胺硫磷等13种农药残留情况。本次检测蔬菜样品24个,其中检出含有被测农药样品8个,%;被测农药不合格的样品3个,%。有5种高毒农药被检出,其中毒死蜱的检出率最高,达到25%,%,甲胺磷、水胺硫磷、%。

Abstract
The ganophosphorus agricultural chemicals take one kind highly effective, Guang Pu the pesticide widely to use in agricultural against evil as well as the family, the warehousing and so on insect disinfestation, but uses after massively, produces the environment harm day by day is also serious. Agricultural chemicals acute poisoning, after specially fruits and vegetables food contamination, initiates munity poison event sometimes occurs. Therefore the establishment fruits and vegetables ganophosphorus remains the examination technology to have the necessity very much. this topic uses the methyl cyanide to soak raises, simultaneously to the eggplant fruit class, the melon class, the sea cabbage class, the cabbage class, the green leaf class, the legumes 6 kind of vegetables altogether 24 varieties, uses in the gas phase chromatography examination ganophosphorus the high poisonous agricultural chemicals methylamine phosphorus, the oxidized rogor, the thimet, the parathion, the methyl parathion, to kill by poison the tick, the phosphate insecticide, the acetyl methylamine phosphorus, the triazole phosphorus, to kill the snout moth sulfur phosphorus, Shui Anliu the phosphorus and so on 13 kind of pesticide residue situation. This examination vegetables sample 24, picks out includes is measured agricultural chemicals sample 8, detection rate %; Is measured agricultural chemicals unqualified sampl
