This paper analyzed the migration regularity and influencing factors of nine kinds of endocrine disrupting chemicals (EDCs) under microwave heating. The plastic samples, treated by microwave and ultrasonic extraction, were analyzed by GC-MS . The initial concentrations of DEA and BHA in plastic samples were low and the other 7 kinds of endocrine disrupting chemicals all migrated. Comparison of SEM photographs before and after migration showed that the surface of migrated plastics became swelling and whity. In the process of cooling, the migration rate increased rapidly at the beginning, but then the amplification of migration rate decreased over time. In the end, the migration reached equilibrium. The migration rates of endocrine disrupting chemicals were increased with the increase of microwave power and action time. The migration rates increased slowly at first， then rapidly in later period.
