摘　　要：综述了农药在土壤、大气和水三相的两两界面的转化情况。有机磷农药在土壤与水两相界面的迁移转化主要受土壤有机质含水量的影响,概括了农药在水气界面的逸度研究和挥发动力学模型,通过逸度模型预测农药在土壤和大气两相界面的迁移活动。The transformation of pesticide at two- phase interface of water, air and soil is reviewed. Migration and transformation of organo - phosphoric pesticide are mainly affected by the content of organic compound and water amount in soil. Besides, fugacity diffusion at the water - gas interface and volatilization kinetics model of pesticide influenced by time and concentration are summarized. Migration of pesticide at the： interface of soil and gas is also predicted by fugacity model.

关 键 词：农药 两相界面 迁移转化
