| 摘 要： | 对北京市郊农田土壤中多环芳烃（PAHs）的种类、含量进行研究，并对其来源和生态风险进行探讨，以期了解京郊农田土壤中PAHs的污染现状和潜在风险，为农业环境保护提供科学依据和理论支持。结果表明：16种PAHs全部检出的检出率为74.4%，PAHs总含量（∑PAHs）范围为7.19~1 811.99 ng·g-1，平均值为460.75 ng·g-1；土壤中PAHs的组成结构主要以2~4环为主，占总含量的78.2%，主要来源为石油和煤的高温燃烧。风险评价结果显示，京郊农田土壤已受到PAHs污染，并具有潜在生态风险。

| Abstract: | The PAHs were used as the goal pollutant in order to study the species, content, main source and ecological risk of PAHs in agricultural soil in suburbs of Beijing. This study can not only understand the pollution characteristics and potential risk of PAHs in agricultural soil in suburbs of Beijing, but also provide support for the decision making of agricultural environmental protection. The results showed that 16 PAHs were generally detected, with the detection ratio of 74.4%. The total PAHs concentrations was in range of 7.19~1 811.99 ng·g-1, with an average value of 460.75 ng·g-1. The dominant compounds were 2~4 ring PAHs, which accounted for 78.2%. PAHs in soil were mainly derived from the fossil oil and the combustion of coal. The analysis of risk assessment showed that the agricultural soil in suburbs of Beijing had been polluted by PAHs and had potential ecological risk. |
