摘要：Distribution behaviors of thifluzamide, fenoxanil, and tebuconazole applied to rice were investigated in South China. Analysis was by a modified QuEChERS method with gas chromatography (thifluzamide and fenoxanil) and liquid chromatography mass spectrometry (tebuconazole). Thifluzamide and tebuconazole partitioned mainly into the soil, with half-lives in the paddy soil of 12-14 and 5.3-7.8 days, respectively. Fenoxanil partitioned mainly into the rice plants, with half-lives of 3.3-4.4 days. The half-lives of thifluzamide, fenoxanil, and tebuconazole in paddy water were 0.17-0.89, 1.8-3.0, and 1.6-4.0 days, respectively. The residues in rice grains at the pre-harvest interval of 14 days were all below the established maximum limit values. The dietary risks assessed as hazard quotients at the pre-harvest interval were less than 1.
