The translocation and degradation of benfuracarb in different soils were studied.The leaching of benfuracarb in soils was described.The vertical distribution of benfuracarb and carbofuran,a metabolic product of benfuracarb,ranged from 0 to 14 cm in soil column.The benfuracarb and carbofuran in the soil column that was lower than 14 cm.Benfuracarb and carbofuran move to lower in soil column with more precipitations.Results indicated that there was little possibility of comtaminat ing the underground water.Results showed that the half-life of benfuracarb was 6.3~8.8 d in three different soils.There were some differnces with different soils.Degradation of benfuracarb was not much more slowly under sterilization condition than that under normal condition.When soils were treated with sterilization,the half-life of benfuracarb is 6.8~10.4 d in three soils.The result suggested that chemdegradation had a greater effect than biodegradation.Within 30 d,benfuracarb was degradated fast and produced carbofuran and 3-hydroxycarbofuran.Carbofuarn are subsequenly degradated irregularly.3-hydroxycarbofuran produced in the process was little.The method based on gas chromatography and NP detector was applied in this study.
