【摘要】 茶叶生产中为了防治病虫草害需要使用种类繁多的农药,有机磷农药是近年来使用较多的一类,本文采用气相色谱法检测了浙江省部分地区绿茶中的有机磷农药残留量,结果显示,有机茶明显好于常规茶样品,检出有机磷农药的四个茶叶样品全部是常规茶,检出的农药为敌敌畏、甲胺磷、乙酰甲胺磷和乐果,其中乙酰甲胺磷是检出率较高、超标也比较严重的有机磷农药。在茶叶炒制加工过程中甲胺磷和乐果残留量逐步减少,敌敌畏残留量基本不变,乙酰甲胺磷则有升有降,说明加工工艺对样品中农药残留量有一定的影响。
【Abstract】 All kinds of pesticides are used in tea production to prevent disease,insect and hasty.One kind of most usually used pesticides is organic phosphor pesticides.Organic phosphor pesticides residue in Green teas produced in some areas of Zhejiang Province were tested by Gas chromatogram(GC)method. The results showed that samples that were found organic phosphor pesticide residue were all the normal tea, no organic tea were found organic phosphor pesticide residue.The methamidophos and dimethoate residue were reduced after the process.The dichlorovos residue keep steadiness and the acephate residue were both reduced and increase during the process.Our results suggest that the process technics can affect the pesticide residue of tea sample.
