%X Under sunlight or high pressure mercury lamp(HPML),the phototransformation of carbendazim in solvents and aqueous solutions was studied.The main results were summarized as follows:Carbendazim decomposed very slowly in aqueous phase, n \|hexane and methanol under sunlight.The photolytic rate of MBC in acetone was high with half\|life of 33.80?h.Photosensitizer such as riboflavin,0 5% acetone and Fe 3 ,can enhance photolysis of MBC in aqueous solutions.Among them,riboflavin is the most senstivive one MBC can be degraded by 53 47% after 16 hours.Three pesticides,namely,triadimefon,butachlor,and carbofuran can affected significantly the photodecomposition of MBC in water under HPML.By 2 hours irradiation,the photoquench efficiency of triadimefon,butachlor and carbofuran on cabendazim are 244 05%,252 81%,and 262 92%,respectively.Under HPML,direct photolysis is the main process.The half\|life in redistilled water is 74 62?min.The photolytic rates of carbendazim in different water types or pH show following sequence:redistilled water>river water>pond water,or,pH4>pH9>pH7.
