摘要
茉莉花喷施水溶性农药甲胺磷(methamidophos),脂溶性农药氯氰菊酯(cypermethrin)、溴氰菊酯(deltamethrin)、氰戊菊酯(fenvalerate),残留量都较高.但用这种鲜花窨制花茶,不会增加茶坯中农药的残留量,茶坯中农残在花茶加工过程中因湿热作用而有所下降.茉莉花喷施农药后,不同农药的降解速度不同,敌敌畏(dichlorvos)和辛硫磷(phoxim)喷后2d基本完全降解;毒死蜱(chlorpyrifos)、硫丹(endosulfan)的半衰期大约1-2d;氯氰菊酯、氰戊菊酯、溴氰菊酯和甲胺磷的半衰期约4d.茉莉鲜花在窨制中其农药残留量有不同程度的下降,但仍维持较高的水平.
Water-soluble pesticide methamidophos (MEP) and fat-soluble pesticides cypermethrin (CYM), deltamethrin (DEM) and fenvalerate(FEL) were sprayed on jasmines, their residues were high. Suffocating tea with the flower did not add the residue to the tea, and the residue even decreased because of damp and heat. The degradation speeds of different pesticides were different when they were sprayed on jasmines. Dichlorvos (DIL) and phoxim (PHO) were almost completely degraded after 2 days. The half-lives of chlorpyrifos (CHP) and endosulfan (ENS) were about 1-2 days; and the half-lives of CYM, FEL, DEM and MEP were about 4 days. The pesticide residue in jasmine tea reduced to different degree, but the level was still relatively high.
