查询词典 pesticide

The results indicated that the pesticide could be distributed through the body and cumulated in peripheral compartment relatively,but it could be eliminated rapidly.With parameters such as t1/2α valued 3.40min,t1/2β 59.03min and Cl 0.018ml·min-1,Its metabolism followed two-compartment open model after administration of 10 mg/kg.It was primary distributed to blood-riched organs and fat tissues and ready to be biotransformed.The metabolic product were detected in choler,which had stronger polarity with retention time 4.25min;and no parent compound was found in both urine and faeces.Key words: Toxicokinetics;Fenamithion;Organophosphorus pesticide

结果显示：螨胺磷在体内全身分布，并有周室富集，消除较快，在10mg/kg静脉注射呈二室模型，t1/2α为3.40min，t1／2β为59.03min，全身清除率Cl0.018ml·min-1；螨胺磷主要分布于血流量大的器官及脂肪组织；螨胺磷在体内不稳定，能被肝脏代谢转化成极性更高的化合物后经由胆汁排出，该成分可在同样的色谱条件下被分离，峰保留时间4.25min；粪尿中均未检出原药。
