摘要
为了探明吉林省中部农业土壤中PAHs的污染现状,系统地测试了该区土壤中PAHs的含量,对土壤中16种PAHs的分布特征及其生态风险进行了探讨。结果表明:吉林省中部农业土壤中PAHs的质量分数为144.5～2355.0μg/kg,且水田土壤中PAHs的含量高于旱田土壤中的含量;土壤PAHs的来源既有燃烧源,又有石油类污染源;目前土壤PAHs以轻微污染水平为主,生态风险评价表明土壤PAHs的生态风险较小。
In order to evaluate the contaminated status of PAHs in the agricultural soil of middle part of Jilin Province,the PAHs concentration of agricultural soil was systematically analyzed and the distribution and ecologic risk of PAHs were discussed.The results showed that the content of PAHs in the agricultural soil ranges between 144.5 μg/kg and 2 355.0 μg/kg,and the PAHs concentration of paddy soil is higher than that of dry farmland.The PAHs of soil mainly come from combustion of fossil fuel and petroleum plllution sources.The soil in this area is weakly contaminated by PAHs at present and it is showed that the ecologic risk of soil PAHs in this area is small.
