中文摘要：本文对香菇从栽培到采后干燥过程中的六种农药（多菌灵，噻菌灵，腐霉利、联苯菊酯、氯氟氰菊酯、高效氟氯氰菊酯）的残留动态进行了调查研究，并对其后的膳食暴露风险进行了评估。试验表明，多菌灵、噻菌灵和腐霉利的半衰期短于联苯菊酯、氯氟氰菊酯和高效氟氯氰菊酯。此外，本文还研究了加工因子和两个干燥过程对农药残留的影响，结果表明，热风干燥处理过程比日晒干燥处理造成的农药残留更多。除对噻菌灵的日晒处理过程外，所有的干燥处理均会造成了一定的农药残留。噻菌灵的估计每日摄入量为每日允许摄入量的0.06%，腐霉利的估计每日摄入量为每日允许摄入量的42.43%。膳食风险评估表明干香菇的六种农药残留量均在人类可接受水平以内。
外文摘要：The dissipation of six pesticides (carbendazim, thiabendazole, procymidone, bifenthrin, lambda-cyhalothrin, and beta-cyfluthrin) in shiitakes from cultivation to postharvest drying process was investigated, and the dietary exposure risk was estimated thereafter. The field trial study indicates that the half-lives of carbendazim, thiabendazole, and procymidone were much shorter than those of bifenthrin, lambda-cyhalothrin, and beta-cyfluthrin. Furthermore, the effects of two drying processes on the residues and processing factors (PFs) were investigated. The results showed that hot-air drying resulted in higher residues than sunlight exposure drying. Both drying processes led to pesticide residue concentration (with PF > 1), except for thiabendazole upon sunlight exposure treatment. The estimated daily intakes (EDIs) ranged from 0.06% of the acceptable daily intake (ADI) for thiabendazole to 42.43% of the ADI for procymidone. The results show that the six pesticide residues in dried shiitakes are still within acceptable levels for human consumption on the basis of a dietary risk assessment.
