摘要: 为探明余姚市2023—2024年主产乡镇杨梅的农药残留和膳食暴露风险,对杨梅鲜果样品和农药投入品开展农药残留分析,分别运用点评估和概率评估模型进行膳食暴露风险研究。结果表明:73批次杨梅鲜果中,共检出19种农药残留,未登记农药13种,杨梅样品的农药检出率为74.0%,超范围使用率为68.4%,多残留检出率为39.7%。从点评估结果来看,急、慢性膳食风险范围分别为0.02%~7.73%和0.01%~6.00%,处于可接受范围内。从概率评估结果来看,50岁以下人群的膳食暴露风险处于可控范围,50~74岁人群的高百分位暴露量可能存在风险。研究表明,余姚市杨梅农药的膳食暴露风险处于可接受范围,中老年人群的高百分位暴露量可能存在风险,建议将吡唑醚菌酯、苯醚甲环唑和氯氟氰菊酯列为风险管控的重点。

Abstract:

To investigate the pesticide residue profiles and dietary exposure risks of Myrica rubra(Chinese bayberry) in major producing towns of Yuyao City during 2023-2024, pesticide residue analyses were conducted on fresh Chinese bayberry samples and pesticide inputs. Dietary exposure risk assessments were performed using point estimation and probabilistic assessment models, respectively. The results revealed that among 73 batches of fresh Chinese bayberry samples, a total of 19 pesticide residues were detected, including 13 unregistered pesticides. The overall pesticide detection rate was 74.0%, the off-label use rate was 68.4%, and the multi-residue detection rate was 39.7%. Point estimation results indicated that the acute and chronic dietary exposure risks ranged from 0.02% to 7.73% and 0.01% to 6.00%, respectively, demonstrating that the dietary exposure risk was within an acceptable range. Probabilistic assessment results showed that the dietary exposure risk was controllable for populations under 50 years of age, whereas high-percentile exposure levels may pose potential risks for the 50-74 age group. Collectively, this study indicated that the dietary exposure risk of pesticides in Chinese bayberry in Yuyao is generally acceptable; however, high-percentile exposure among middle-aged and elderly populations may present potential risks. It is recommended that pyraclostrobin, difenoconazole, and lambda-cyhalothrin should be prioritized for risk management.

Key words: Myrica rubra, pesticide residue, probability estimation, dietary risk
