Contamination and health risk hazards of organophosphorus pesticides residues in vegetables were studied. Ethyl-chlorpyrifos, observed at an average level of 0.211+/-0.010mgkg(-1) in 42% of tomato, 0.096+/-0.035mgkg(-1) in 10% of eggplant and 0.021+/-0.013mgkg(-1) in 16% of pepper was below the 0.5mgkg(-1) MRL. Dichlorvos was the most frequently detected residue in all the samples analyzed. Levels of malathion in tomatoes (0.120+/-0.101mgkg(-1)) and pepper (0.143+/-0.042mgkg(-1)) exceeded the MRL of 0.1mgkg(-1). Health risks were found to be associated with methyl-chlorpyrifos, ethyl-chlorpyrifos, and omethioate in tomatoes and methyl-chlorpyrifos, ethyl-chlorpyrifos, dichlorvos, monocrotophos and omethioate in eggplant. Routine monitoring of these pollutants in food items is required to prevent, control and reduce the pollution and to minimize health risks.
研究了蔬菜中有机磷农药残留的污染情况及健康风险危害。在42%的番茄中检测到毒死蜱乙酯，平均含量为0.211±0.010mg/kg(-1)；在10%的茄子中检测到毒死蜱乙酯，平均含量为0.096±0.035mg/kg(-1)；在16%的辣椒中检测到毒死蜱乙酯，平均含量为0.021±0.013mg/kg(-1)，均低于0.5mg/kg(-1)的最大残留限量。敌敌畏是所有分析样品中最常检测到的残留。番茄（0.120±0.101mg/kg(-1)）和辣椒（0.143±0.042mg/kg(-1)）中的马拉硫磷含量超过了0.1mg/kg(-1)的最大残留限量。发现番茄中的甲基毒死蜱、毒死蜱乙酯和氧乐果以及茄子中的甲基毒死蜱、毒死蜱乙酯、敌敌畏、久效磷和氧乐果存在健康风险。需要对食品中的这些污染物进行常规监测，以预防、控制和减少污染，并将健康风险降至最低。
