中文摘要:

      目的 评估目前山东主要苹果产区的农药残留水平, 为农药残留监管提供科学依据。方法 对采自山东苹果主产区的110个苹果样品运用现有的标准方法进行102种农药残留分析检测, 利用急性参考剂量(acute reference dose, ARfD)和国家估计短期摄入量(international estimated short-term intake, IESTI)公式评估苹果农药累积急性风险。结果 山东省苹果共检出26种农药残留, 多残留(2种农残及以上)样品占样品总数的78%, 所有样品检出农药残留量均未超过规定的最大残留限量值; 检出苹果上禁用农药灭多威和未登记农药噻嗪酮、螺螨酯、杀铃脲; 有机磷类、菊酯类、三唑类和烟碱类农药在山东苹果中累积急性膳食摄入风险(%ARfD值)分别为37.7%、7.37%、0.28%和1.53%。结论 山东省苹果农药残留种类较多, 残留水平不高, 有机磷类、菊酯类、三唑类和烟碱类农药累计急性摄入风险较小, 但需重点关注苹果上禁用农药和未登记农药。

英文摘要:

      Objective To assess the levels of pesticide residues and provide scientific basis for regulation of pesticide residues in major apple producing areas in Shandong province. Methods Residues of 102 pesticides in 110 apples from main fruits areas were detected by standard methods The method of cumulative acute risk assessment of pesticide in apple was established by acute reference dose (ARfD) and international esti-mated short-term intake (IESTI). Results Many types of pesticide residues (26 kinds) were detected in apples. Multiple residues (2 kinds of pesticides and above) accounted for a higher sample proportion of the total number of samples (78%). All pesticide residues detected in the samples did not exceed the maximum residue limit (MRL). Banned methomyl and unregistered buprofezin, spirodiclofen, and triflumuron pesticides were detected. The values of accumulation acute risk of organophosphate, pyrethroid, triazoles and neonicotinoid pesticides were 37.7%, 7.37%, 0.28% and 1.53%. Conclusion Many types of pesticides residue were detected, but the levels were not high. Organophosphate and pyrethroid, triazoles and neonicotinoid pesticides accumulate less risk of acute dietary intake of apples in Shandong, and the likelihood of harm is unlikely. The banned pesticides and unregistered pesticides are needed to focus on.
