Results 4 kinds of organophosphorus (methyl parathion, DDVP, parathion, phorate) and 2 kinds of pyrethroid pesticides (Cypermethrin, Fenvalerate) were detected in the vegetables in 2003. 4 kinds of pesticides were detected in spinach,tomato, leek, capsicum, celery and cucumber, but not in cabbage and cole. The parathion residues and the rate of exceeded limit in spinach, capsicum was 0.007 mg/kg, 0.036 mg/kg and 9.09% respectively. The phorate residues in tomato was 0.0150 mg/kg, the rate of exceed limit was 12.5%. The most popular pesticide residued in these vegetables was methyl parathion which was detected in 5 kinds of vegetables, DDVP and cypermethrin was detected in 3 kinds of vegetables. 4 kinds of organophsphorus (DDVP, Methamidophos, Omethoate, Chlorpyrifos) and 3 kinds of pyrethroids pesticides (Cypermethrin, Deltamethrin, Fenvalerate) residues were detected in 8 kinds of vegetables in 2004. 6 kinds of pesticide were detected in leek, pesticides were also detected in the other vegetables. Methamidophos residue in leek was 0.705 0-22.560 0 mg/kg, the rate of exceed limit was 100%, omethoate residue and the rate of exceed limit in leek and capsicum was 0.219 5-0.414 5 mg/kg, 0.0170 mg/kg and 100%,14.29% respectively.
