摘要
对新昌县生产基地和农贸市场随机采集的共246份蔬菜样本进行了农药残留检测,检测有机磷类、有机氯类、拟除虫菊酯类和氨基甲酸酯类农药残留22项。结果表明,检出农药残留样本36份,总检出率为14.6%,农药超标样本4份,总超标率为1.6%。第三季度蔬菜的农药残留全年最高,检出率和超标率分别为22.1%和4.4%。不同种类的蔬菜农药残留检出率排序为叶菜类>豆类>芸薹属类>根茎类>茄果类>瓜菜类>薯芋类>葱蒜类,仅叶菜类、瓜菜类和茄果类农药残留超标。由此表明,新昌县蔬菜农药残留依然存在,少数蔬菜中农药残留超标,应加大监测管理力度,确保市民食用蔬菜安全。

Pesticide residue of the third quarter was the highest in whole year, and detection rate and excessive rate were 22.1% and 4.4%respectively. The rank of pesticide residue detection rate of different kinds of vegetables was leaf vegetables>beans>Brassica genus>root vegetables>solanaceous fruit vegetables>cucurbitaceous vegetables>tuber vegetables>bulb vegetables, and only pesticide residues of leaf vegetables, cucurbitaceous vegetables and solanaceous fruit vegetables exceeded standard.
