摘要: 为探讨广东省主要叶菜农药残留膳食暴露风险,对2014年和2015年广东省6 种叶菜样品中的33 种农药残留进行评估分析。采用点评估和基于@Risk v5.7评估软件的概率评估方法,对检出率超过5%的农药进行膳食暴露风险评估(包括急性暴露风险评估和慢性暴露风险评估)。结果显示,有22 种农药检出,检出率在1.7%~36.1%之间;检出率超过5%的农药有10 种,分别为吡虫啉、啶虫脒、多菌灵、氯虫苯甲酰胺、烯酰吗啉、灭蝇胺、联苯菊酯、苯醚甲环唑、毒死蜱、甲霜灵。其急性暴露风险熵在1.31~28.22之间,99%人群的慢性暴露风险熵在0.87~70.00之间,提示这10 种农药残留膳食暴露风险水平在可接受范围,但慢性暴露风险熵较高的农药种类如毒死蜱、苯醚甲环唑等应引起关注。本研究为蔬菜质量安全风险管理提供了科学依据。

Abstract: To discuss the health risk associated with dietary exposure to pesticide residues in staple leaf vegetables in Guangdong province, 33 target pesticides in 6 kinds of leaf vegetables collected in 2014 and 2015 were evaluated. Point evaluation and probability assessment with @Risk v5.7 software were used to assess the health risk derived from acute and chronic dietary exposure to pesticides with a detection rate of over 5%. Totally, 22 pesticides were detected with a detection of rate of 1.7%–36.1% and there were 10 pesticides with a detection rate of over 5% including imidacloprid, acetamiprid, carbendazim, chlorantraniliprole, dimethomorph, cyromazine, bifenthrin, difenoconazole, chlorpyrifos and metalaxyl. The risk quotients for acute dietary exposure to these pesticides were between 1.31 and 28.22, while those for chronic dietary exposure were between 0.87 and 70.00 for 99% of consumers, suggesting the health risk associated with their dietary exposure was acceptable. More attention should be paid to the pesticides with high chronic exposure risk quotients such as chlorpyrifos and difenoconazole. Findings from this study provide scientific grounds for risk management of vegetable quality and safety.
