In order to know behaviors of pesticides in the environment, changes in residual patterns of 35 organophosphorus, 28 organonitrogen, 9 organochlorine and 7 pyrethroid pesticides after boiling and heating, and by alterations in pH were investigated. A high correlation between the solubility of water and the residual percentage of pesticides 30 min after boiling at 100℃ was recognized, and a similar relation was also detected between the vapor pressure and the residual percentage of pesticides 30 min after heating. With an alteration in pH, it is suggested that formotion, chinomethionat, bendiocarb, cypermethrin, fluvalinate and fenvalerate were hydrolyzed in alkaline conditions. And also carbosulfan and amitraz were hydrolyzed in acidic conditions. But 71 in 79 kinds of pesticides did not decompose from pH 6 to 10. It was identified by GC-MS that carbosulfan was decomposed into carbofuran by the acidic hydrolysis.
