ABSTRACT This research aims to apply gaseous ozone to degrade pesticides (cypermethrin and dicofol) residues in dried basil leaves and to investigate their qualities after fumigation. Sweet basil, holy basil, hairy basil, and tree basil were fumigated with 200 mg/L gaseous ozone. The result showed that half-life of cypermethrin and dicofol in dried basil under ozone fumigation were in the range of 13.1–31.6 and 9.4–18.9 min, respectively. Ozone fumigation exhibited at least 99.9% reduction of pesticide residue in comparison with self-degradation. In addition, this process does not significantly affect phenolic compounds and antioxidants in dried basil at 95% confidence level.

气态臭氧熏蒸降解罗勒干叶中氯氰菊酯和三氯杀螨醇农药残留

摘要 本研究旨在应用气态臭氧降解干罗勒叶中的农药（氯氰菊酯和三氯杀螨醇）残留物，并研究熏蒸后的质量。甜罗勒、圣罗勒、多毛罗勒和树罗勒用 200 mg/L 气态臭氧熏蒸。结果表明，臭氧熏蒸干燥罗勒中氯氰菊酯和三氯杀螨醇的半衰期分别为 13.1-31.6 和 9.4-18.9 分钟。与自降解相比，臭氧熏蒸显示至少 99.9% 的农药残留减少。此外，在 95% 的置信水平下，此过程不会显着影响干罗勒中的酚类化合物和抗氧化剂。
