生化試驗法在蔬菜殘留農藥篩檢上可行性之探討

INVESTIGATION OF PESTICIDE RESIDUE IN VEGETABLE BY BIOCHEMICAL METHOD AND GAS CHROMATOGRAPHY

本計劃以生化法偵測37種農藥之最低感度在0.0016-5440 ppm，而以氣相層析法偵測23種農藥之最低檢出量在0.001-0.lppm 之間。並利用生化法檢驗市售蔬菜600件之農藥殘留情形，檢驗結果為陽性者佔2.5%，其中有100件檢體同時以生化法及氣相層析法分析。以化法檢出為陽性者有8件；以氣相層析法檢出有農藥殘留者有30件（7件與規定不符，7%），其中只有3件是以兩種方法均檢出有農藥殘留。結果顯示，氣相層析法之檢出率比生化法高，生化法雖有其快速偵測之優點，但除了許多常用農藥無法檢出外，其可偵測之農藥所測得之抑制率無法與公告之容許量比較，作為判定之依據。

The pesticide Residue in 600 samples of vegetables purchased from markets was analyzed by biochemical method. 15 samples (2.5%) was positive. 100 .samples of them was anylyzed by both Biochemical method and gas chromatography. 8 samples was found positive by biochemical method. Pesticide residue was detected in 30 samples by gas chromatography. Only 3 Samples was found pesticide residue by both methods.
