中文摘要:

      目的 了解河北省石家庄市蔬菜中农药残留现状, 评估蔬菜中农药残留的慢性膳食暴露风险。方法 随机采集2018年石家庄市主要蔬菜生产基地和集贸市场的蔬菜样品, 采用NY/T761-2008《农药残留分析样本的采样方法》检测3462批次8类蔬菜样品中的65种农药残留, 分析石家庄市蔬菜中农药残留现状, 并结合我国居民的蔬菜消费情况和食品安全指数对石家庄市居民于蔬菜中摄入的农药风险进行慢性膳食暴露评估。结果 石家庄市抽检的蔬菜中农药残留检测合格率达99.80%, 8类蔬菜样品中有1类超标, 检出率为3.15%, 超标率0.20%, 超标均为叶菜类蔬菜。定量检测出13种农药, 超标农药为水胺硫磷和毒死蜱, 分别超标5批次和2批次。对所有检出农药进行慢性膳食暴露评估结果表明, 水胺硫磷和毒死蜱的日摄入量相对较高, 所有检出农药的食品安全指数值均小于1。结论 石家庄市蔬菜中农药残留量的安全风险均在安全范围内, 居民蔬菜中农药残留的慢性膳食暴露风险小, 水胺硫磷、毒死蜱是潜在的风险因子, 应重点防患其残留风险。

英文摘要:

      Objective To understand the current status of pesticide residues in vegetables in Shijiazhuang city, Hebei province, and to assess the chronic dietary exposure risk of pesticide residues in vegetables. Methods The vegetable samples were collected randomly from vegetable production bases and farmer’s markets in Shijiazhuang of 2018, and the pesticide residues of the current situation of 65 kinds in 3521 batches were detected according to the method of NY/T 761?2008 Sampling method for pesticide residue analysis samples. The present situation of pesticide residues in vegetables in Shijiazhuang city was analyzed, the chronic dietary exposure risk of pesticide residues was evaluated by the food safety index method with vegetable consumption of residents in Shijiazhuang. Results The qualified rate of pesticide residue detection in the vegetables sampled in Shijiazhuang reached 99.80%. Among 8 kinds of vegetables, one kind exceeded the standard, with the detection rate of 3.15% and the exceeding rate of 0.20%, which were all leaf vegetables. Totally 13 kinds of pesticides were quantitatively detected. The pesticides exceeding the standard were isocarbophos and chlorpyrifos, which exceeded the standard in 5 batches and 2 batches respectively. The results of chronic dietary exposure assessment of all detected pesticides showed that the daily intake of isocarbophos and chlorpyrifos was relatively high, and the food safety index value of all detected pesticides was less than 1. Conclusion The safety risks of pesticide residues in vegetables in Shijiazhuang city are all within the safe range. The chronic dietary exposure risk of pesticide residues in vegetables of residents is small, and isocarbophos and chlorpyrifos are potential risk factors, so the residue risks should be mainly avoided.
