摘要：Anilofos is the organophosphorus herbicide widely used in China. However, little is known on the processes governing the environmental fate of anilofos in soils and its environmental risk for groundwater. Several environmental fate studies were performed concerning the degradation, sorption, photolysis and mobility of anilofos in soils. The degradation of anilofos in three Chinese soil samples followed first-order kinetics, with half-lives between 64.2 d-161.2 d. The adsorption coefficient (K-F) values for the three soils were 10.67 (loam), 31.29 (clay) and 11.63 (sand). No notable photolysis of anilofos occurred on soil surface. Leaching tests, performed in manually packed soil glass-plate, indicated that anilofos moved very slowly on the three types of soil thin layer. Thus, the leaching behavior of anilofos coincided well with the results of the batch sorption and degradation experiments. The data generated from this study could be helpful for risk assessment studies of the pesticide in the environment.
