| Abstract: | A QuEChERS pretreatment method using dispersive solid-phase extraction was established, and the residual amount of metamifop and cyhalofop-methyl and their metabolites in brown rice, rice husk and straw samples were determined by ultra performance liquid chromatography tandem mass spectrometry （UPLC-MS/MS）. The results showed that, none of the residues of metamifop and cyhalofop-methyl in rice grain and brown rice harvested at maturity were detected. The risk quotients （RQ） for these pesticides were assessed by comparing the country's estimated daily intake with the acceptable daily intake. The results of the dietary risk assessment showed that the RQ of metamifop and cyhalofop-methyl in brown rice were 0.87% and 1.9%, respectively. Consumers have lower health risk after consumption. |
