英文摘要 | The dissipation and residue of pymetrozine in rice field ecosystem were studied based on a novel and reliable analytical method for pymetrozine in paddy water, soil, rice straw, brown rice, and rice husk. The pymetrozine residues were extracted with acetonitrile and cleaned up by Carb-NH2 SPE cartridge and determined by high-performance liquid chromatography electrospray ionization tandem mass spectrometry (LC-ESI-MS-MS). The dissipation of pymetrozine followed first-order kinetics and its half-lives ranged from 1.7 to 1.8 days in paddy water, 5.1 to 5.7 days in soil, and 2.3 to 2.6 days in rice straw, respectively. At harvest time, the highest final residues of pymetrozine varied in soil among three geographical fields and were below the limit of detection in rice tissues. The recommended dosage was considered to be safe for human beings and animals, and the results were helpful in setting maximum residue limit for pymetrozine in rice. |
