This method can be used to detect 16 pesticides in 30 minutes, including organophosphorus (parathion-methyl, phorate, isofenphos-methyl, malathion, chlorpyrifos, fenthion), organochlorine (dichlororos, heptachlor, chlorothalonil,α-hexachlorocyclohexane,γ-hexachlorocyclohexane,δ-hexachlorocyclohexane, p, p'-DDE, p, p'-DDD), pyrethroids and triadimefon in vegetables.

采用选择离子-气相色谱-质谱联用方式,依据保留时间和特征离子丰度比,可以在30 min之内检测有机磷(甲基对硫磷、甲拌磷、甲基异柳磷、马拉硫磷、毒死蜱、倍硫磷)、有机氯(敌敌畏、七氯、百菌清、α-六六六、γ-六六六、δ-六六六、p, p'-DDE、p, p'-DDD)、除虫菊酯、三唑酮等16种农药。

The single toxicity of Chlorpyrifos, Diazinon and Malathion and joint toxicity of ternary mixtures of organophosphate insecticides to photobacterium phosphoreum were determined.

实验测定了三种有机磷杀虫剂毒死蜱、二嗪农和马拉硫磷三种杀虫剂对发光菌的单一毒性,以及固定比率配比下三种有机磷杀虫剂的三元混合体系的联合毒性效应。

Chlorpyrifos mehtyl with different dosages of 3,5,10 mg/kg compared with malathion 15 mg/kg in grain silo,each contented 40 thousand kilograms of rice was studied.To be sprayed by machine when loading to silo and to be observed two years through all experiment,the effective control to sitophilus zeamais of chlorpyrifos mehtyl 5 mg/kg can be protected more than six months,and 10 mg/kg over one year.

报道了甲基毒死碑(化学名称为二甲基O-3,5,6-三氯-2-吡啶基硫逐磷酸酯)3、5、10 mg/kg不同剂量,以防虫磷15 mg/kg作比较,在立筒库星仓内,每筒40000 kg稻谷,机械喷雾法处理,储藏二年,经生物测定对玉米象药效,甲基毒死蜱5 mg/kg可达半年以上,10 mg/kg可达一年以上防护期。

The results show that 60Co-γ ray radiation has the most remarkable effect on the degradation of organophosphorus pesticides such as fenitrothion, parathion, methyl-parathion, phorate and chlorpyrifos and the maximum degradation rates are over 85%. The degradation rates of methamidophos, acephate, malathion ,dimethoate are slightly inferior to them and the optimum degradation rates is just only 34.70%. At the same time, the contents of soluble total sugars, glucose, fructose, sucrose and total sugars in apple juice decrease unconspicuously, but the total acid content in apple juice and its color value and clarity increase. Based on a comprehensive consideration of the 60Co-γ radiation effect on the actual degradation of organophosphorus pesticides in apple juice and its main chemical and physical indexes, organophosphorous pesticides residue will be decreased to a lower level with radiation dose of about 5 kGy but the main chemical and physical indexes of export apple juice can not be affected.

结果表明: 60Co-γ射线辐照处理对苹果汁中杀螟硫磷、对硫磷、甲基对硫磷、甲拌磷、毒死蜱降解效果最为显著,最高降解率均在85%以上;对苹果汁中甲胺磷、乙酰甲胺磷、马拉硫磷和乐果的降解效果不显著,最高降解率仅为35%;在0~9 kGy辐照剂量范围内降解苹果汁中有机磷农药的同时,会使苹果汁中的可溶性固形物、葡萄糖、果糖、蔗糖及总糖含量轻微降低,苹果汁的总酸度有所增加,苹果汁的色值及透光率提高;综合分析60Co-γ射线辐照对苹果汁中有机磷农药的实际降解效果及对苹果汁主要理化指标的影响,选用5 kGy的辐照剂量已完全使苹果汁中的有机磷农药残留降低到一个很低的水平,又不会对苹果汁出口主要理化指标造成影响。
