Chapter three is the degradation of Abamectin in soils. The results show:(1) The decomposition of Abamectin is fastest in Aquic Cambosols while slowest in Udic Cambosols in five kinds of different soils.(2) Organic matter content in soil is the most important factor which influences the degradation half-life of Abamectin in soil, and their relative coefficient arrives at 0.9323, but pH value, total nitrogen, CEC and field maximum moisture capacity correlate little.(3) Soil organic matter, soil temperature and pesticide concentration can obviously affect Abamectin degradation in soil, in addition, the degradation half-life of Abamectin in sterilized soil is far more than that in non-sterilized soil, which maybe contributes to microorganism in soil. Chapter four is the microbial degradation of Abamectin.

第三章研究了阿维菌素在土壤中的降解，结果表明：(1)五种不同类型土壤中，阿维菌素在潮湿雏形土中降解最快，而在湿润雏形土中降解最慢；(2)土壤有机质含量与阿维菌素半衰期相关性较强，相关系数为0.9323，而土壤酸碱度、总氮含量、阳离子交换量和田间最大持水量等因子与阿维菌素半衰期相关性较小，说明影响阿维菌素在土壤中降解的最主要因子为有机质含量；(3)土壤有机质、土壤温度和农药浓度等因素对阿维菌素在土壤中的降解有较大影响，此外灭菌条件下其降解半衰期远大于未灭菌时的半衰期，这表明阿维菌素在土壤中的降解可能和土壤微生物有关。

The result shows that when HPLC adopts 254 nm as scan wavelength, and the mixture of acetonitrile and water according to appropriate proportion as flowing phase, the parameters such as accuracy, repetition and precision et al for the method are all good to satisfy the essential rules of pesticide residue determination.Chapter three is the degradation of Abamectin in soils. The results show:(1) The decomposition of Abamectin is fastest in Aquic Cambosols while slowest in Udic Cambosols in five kinds of different soils.

Their half lives were 27.29 and 69.16 days respectively. Monocrotophos degraded into both methanol extractable and unextractable residues in the submerged soil.The analysis of 14C-methanol extractable. residue by TLC and ARG indicated that degraded products of monocrotophos were triether phosphate,;N-de-methyl Azodrin, O, O-dimethyl-vinyl-phosphatc,O-demethyl Azodrin,and O, C-demethyl Azodrin.The principal degraded extratable product of monocrotophos was triether phosphate, which incresed from 5% of the parent solution of monocrotophos to a range of 28-83%, furthermore and its degradation process was much faster in the unterilized soil than in the sterilized soil.

久效磷在淹水土壤中降解为甲醇可抽提态和不可抽提态残留物，对甲醇可抽提态残留物经TLC和红外光谱分析表明，其降解物为磷酸三酯、N-去甲基久效磷、O，O-二甲基乙烯基磷酸酯，0-去甲基久效磷，以及O，C-去甲基久效磷，但主要为磷酸三酯，其含量由母液中的5％增加到28—83％，这种降解过程，在未灭菌土壤中比在灭菌土壤中快。
