摘要： Understanding the fate of dinotefuran, flonicamid, and their metabolites is crucial for accurate dietary exposure assessment and human health. The dissipation and removal of dinotefuran, flonicamid, and their metabolites from apple cultivation to consumer's plate were studied. The results of field and storage experiments indicated significant differences in half-life at different doses. And the half-life was shorter in the field than that in storage. During washing, the residues of all target compounds were decreased. Among washing solutions, the PF values of each pesticide gradually decreased with the increasing washing time and washing solution concentration. 2 % NaHCO3 produced best removal effect after washing 15 min. Various food processing techniques, including peeling, fermentation, clarification, blanching, drying, enzymolysis, and simmering, were used to confirm the most effective way to remove these target compounds. For majority processes, the PF values were < 1, and the peeling and fermentation could obviously reduce pesticide residues. The risk quotients were < 100 %, implying that the risks were acceptable. This study provided a necessary information for the use of pesticides in apple cultivation and improvement of processing technology to ensure food safety.
