Abstract: Analysis of residues of pesticides in vegetables in southern Jiangsu was conducted in March of 2003. Results indicate that the residues of organochlorine pesticides（OCPs）ranged from not detected（ND）to 31.7(μg·kg^-1).The residues of HCHs in the samples from vegetable production bases were higher than those in the samples from traditional vegetable fields.Most of DDT has been resolved into p,p′-DDE and p,p′-DDD.The residues of pyrethroid ranged between ND and 46.9(μg·kg^-1).Cypermethrin,fenvalerate and deltamethrin were found to be quite higher than others in the form of residue in vegetables.The residues of carbamate ranged from ND to 111.9(μg·kg^-1).The residues of methiocarb and 3-hydroxycarbofuran were widely detected and quite high in concentration,which were much higher in the samples from traditional vegetable fields than from vegetable production bases.The detection rate of aldicarb sulfone was lower than those of aldicarb and aldicarb sulfoxide.The residues of all the pesticides except aldicarb and carbofuran were far below the related national hygiene standard for hazard-free vegetables.
