通过田间试验,研究了丙溴磷在稻田中的残留动态过程,借助气相色谱技术,得到添加回收率为80.1～113.2%,相对标准偏差为2.7～9.4%。丙溴磷在稻田水、土壤及水稻植株中的降解半衰期分别为1.9～2.2d,3.6～4.3d,1.8～2.5d;丙溴磷在稻田水、稻田土壤及水稻植株中的最低检出浓度分别为5.0×10-2mg/L、5×10-2、5.0×10-2mg/kg。

A method for determining residue dynamics of profenofos in paddy field was established by field experiments.The results showed that the recoveries with the analytical method were in range of 80.1～113.2% with the relative standard deviation(RSD) of 2.7～9.4%.The half-life of profenofos in water,soil and plants were respectively 1.9～2.2d,3.6～4.3d,1.8～2.5d.Minimum detectable concentration of profenofos in water,soil and plants were...
