      目的 调查研究2024—2025年西宁市生鲜果蔬农产品的农药残留情况。方法 本研究采用酶抑制法对西宁市某农产品交易市场和产地采购的样品, 185个生鲜蔬菜和125个生鲜水果, 其中生鲜蔬菜13464批次, 生鲜水果5712批次, 共计310个品种19176批次样品, 进行有机磷和氨基甲酸酯类农药残留快速检测与分析。结果 共有30个蔬菜品种、7个水果品种, 60批次样品检测出农药残留超标。其中, 超标率前5的果蔬是黄瓜、青笋、香笋、旱瓜和线茄。农药残留超标样品的检测值在51.30%~99.89%之间, 总体定性初筛阳性率为0.33%, 合格率在98.92%~99.94%之间, 整体样品合格率为99.67%, 合格率较高。结论 2024—2025年西宁地区生鲜果蔬农产品中农药残留情况处于相对安全的水平, 但仍存在农药残留超标的情况。建议持续加强检测与监测, 进一步保障市民的食品安全问题。

英文摘要:

      Objective To investigate and study the pesticide residue situation of fresh fruits and vegetables in Xining City from 2024 to 2025. Methods This study employed the enzyme inhibition method to conduct rapid detection and analysis of organophosphorus and carbamate pesticide residues in samples from a fresh agricultural product trading market and production sources in Xining City, involving 185 fresh vegetables and 125 fresh fruits. Specifically, 13464 batches of fresh vegetables and 5712 batches of fresh fruits, totaling 310 varieties and 19176 batches of samples were tested. Results There were 30 vegetable varieties and 7 fruit varieties, and 60 batches of samples had been tested for pesticide residues exceeding the standard. Among them, the top 5 fruits and vegetables with the highest over-standard rates were cucumbers, stem lettuce, fragrant asparagus, drought-tolerant melon and eggplant. The inhibition rates of the samples with pesticide residues exceeding the standard ranged from 51.30% to 99.89%. The overall qualitative preliminary screening positive rate was 0.33%, and the pass rates were between 98.92%–99.94%. The overall sample pass rate was 99.67%, which was relatively high. Conclusion The pesticide residue situation of fresh fruits and vegetables in Xining City from 2024 to 2025 is at a relatively safe level, but there are still cases of pesticide residues exceeding the standard. It is recommended to strengthen detection continuously and monitoring to ensure food safety for citizens further.
