蔬菜中常用農藥之殘留調查研究

STUDIES ON PESTICIDE RESIDUES OF SOME COMMON USED PESTICIDES IN VEGETABLE

以火焰光度檢測器（Flame Photometric Detector）之氣相層析儀，分析市售蔬菜560件，其農藥檢驗項目為Ethyl parathion、Malathion Diazinon、Mevinphos、Dichloryos、Trichlorfon、Carbofuran、Naled、Sumithion及Methyl parathion等10種。其中32件發現有農藥殘留佔總件數之4.82％。其最高殘留量為1.09 ppm 1件，其他均在0.13 ppm以下。由統計數字及分佈情形顯示，春季（1～3月）農藥殘留出現之件數最多。四季中台灣北部比南部出現率為多。其中parathion不得使用於蔬菜之農藥殘留在蔬菜中是值得注意的問題。 With Flame Photomatric Detector GC to determine 560 peices of vegetable from markets was applied on ten kinds of pesticides, which are ethyl parathion, malathion, diazinon, mevinphos, dichlorvos, trichlorfon, carbofuran, naled, sumithion and methyl parathion. The result showed 32 peices of them had trace pesticide residues. In 4.82% detectable samples, the maximum residue was 1.09 ppm and the others were all below 0.16 ppm. The statistical data showed, most of detectable vegetables were grown in spring (January to March) and happened mostly in the north of Taiwan through the year. The attentive result reminded that the parathion pesticied is still used commonly on vegetables.
