Contamination and Health Risk Assessment of Pesticide Residues in Vegetables from Agricultural Fields of Gazipur District, Bangladesh

摘要

A study was conducted to investigate the contamination and health risk assessment of pesticide residues in vegetables from agricultural fields of Gazipur district, Bangladesh. Ten vegetable samples (VS) were analyzed for some selected organochlorines,organophosphorus, carbamates and pyrithrium pesticides using High Performance Liquid Chromatography (HPLC) with (photo diode array) PDA detector. The results showed that none of the vegetable samples were contaminated with organochlorine pesticides. Sample VS-5(lady's finger) was found contaminated with ethion residue at 1.80 mg/kg. VS-1 (Brinjal) and VS-5 (Lady's finger) were contaminated with fenitrothion residues at 0.166 mg/kg and 0.170 mg/kg, respectively. Health indices of acephate, cypermethrinand fenitrothion in brinjal were 0.363, 0.002 and 0.475 respectively and in lady's finger for ethion and fenitrothion were 10.350 and 0.490 respectively. The data indicated a significant effect for regular monitoring programs of pesticide residues in vegetables, to protect consumers' health.
