The transformation of acetamiprid during Agaricus bisporus industrial production was investigated by testing its residues in cover-soil, compost and fruits using ultra performance liquid chromatography(UPLC-PDA). The samples were extracted with acetonitrile and purified by dispersive solid phase. Acetamiprid residue was then determined by UPLC-PDA. At 0.02-3 mg/kg spiked levels,the average recoveries for cover-soil, compost and fruits were from 81% to 97%(RSDs ≤9.6%). In different application levels, the di...
