Abstract

From year 2000 to 2006, a total of 8,971 vegetable samples had been analyzed for pesticide residues. These samples were screened for organophosphorus (OP), organochlorine (OC), synthetic pyrethroid (PY), dithiocarbamate (EBDC) and carbamate (CA) pesticides using gas chromatograph (GC) and liquid chromatograph (LC). The analysis results shown that OP pesticides were frequently found exceeding the Maximum Residue Limit (MRL) with acephate, methamidofos and chlorpyrifos accounted for 46.5% of the total samples violation. Other pesticides OC, PY and EBDC were also commonly exceeding the MRL. Nevertheless, only about 4.9% of the samples were found to contain excessive residues.
