摘要
以GC/MSD内标法分析了广州五个地区菜地中 1 6种多环芳烃 (PAHs)的分布 ,结果表明 ,菜地土壤中∑PAHs最大为 30 77μg·kg- 1 ,最小为 42 μg·kg- 1 ,绝大部分土壤样品中的∑PAHs含量在 2 0 0 μg·kg- 1 以上 ,属中度污染 .
This work aims to investigate the extent of pollution by polynuclear aromatic hydrocarbons in soils for planting vegetables and the risk of vegetables produced in the soils.Polynuclear aromatic hydrocarbons in the soils were quantified by GC/MSD with an internal standard method.The results show that the maximum value of 16 PAHs is 3077μg·kg -1 ,and the minimum value is 42μg·kg -1 .The total PAHs in most of the samples are higher than 200μg·kg -1 and were classified as the moderate pollution level.
