| 中文摘要: |
| 采用顶空-气相色谱-质谱法，对南宁、北海、钦州和防城港等4个北部湾区域城市蔬菜种植基地60份土壤样品中的代森锌类农药残留进行检测。结果表明，南宁市的15份土壤样品均未检出代森锌类农药残留；北海市有5份土壤样品检出代森锌类农药残留，检出率为33.3%，其质量比范围为0.005 2 mg/kg ～0.034 6 mg/kg；钦州和防城港2市30份土壤样品均检出代森锌类农药残留，检出率为100%，其质量比范围为0.004 9 mg/kg～0.674 mg/kg。 |

| The residual mancozeb in 60 soil samples in the vegetable planting base from Guangxi Beibu Gulf was determined by headspace gas chromatography mass spectrometry. The results showed that all the 15 samples from Nanning were not detected, 5 samples from Beihai were detected, the detected rate was 33.3%, and the concentration ranged from 0.005 2 mg/kg to 0.034 6 mg/kg. All of the 30 soil samples from Qinzhou and Fangchenggang were detected, and the concentration ranged from 0.004 9 mg/kg to 0.674 mg/kg. |
