摘要: 为探讨氧化乐果在果蔬中的残留分布,利用气相色谱法对苹果和大白菜中的不同部位进行测定分析。结果表明:大白菜叶中的氧化乐果残留量高于大白菜柄,整株大白菜中残留量由外向内依次降低;苹果果皮中残留量最高,果肉、果核残留量依次降低;大白菜和苹果中氧化乐果的自然降解速率在10~15d内最快。

Abstract: To investigate the distribution of omethoate residues in fruits and vegetables, different parts of Chinese cabbage and apple were analyzed by gas chromatography (GC). The results indicated that the contents of omethoate residues in Chinese cabbage leaves was higher than that in the stems and declined gradually from outside to inside in the whole cabbage; the highest, middle lowest contents of omethoate residues was found in the peel of apple, followed by in the pulp and in the core of apple successively; and the maximal natural degradation rates of omethoate in Chinese cabbage and apples appeared around 10-15 days after spraying on their surface.

Key words: gas chromatography, omethoate, residue, natural degradation rate, Chinese cabbage, apple
