多环芳烃对土壤环境影响的调查与思考

以新余钢铁城市为例,对其土壤中多环芳烃（PAHs）含量进行了定量分析,研究其分布特征,初步探讨其污染水平,并对土壤PAHs污染防治,减少对农作物污染提出了建议。对典型区域土壤中采集样品,对8种可能高致癌PAHs：苯并a]蒽（4）、屈、苯并b]荧蒽（4）、苯并k]荧蒽（4）、苯并a]芘（5）、二苯并a,h]蒽（5）、苯并gh i〗]苝（6）、茚并（1,2,3-cd）芘（5）,运用高压液相色普仪方法,进行分析测定,结果显示,样品土壤中8种PAHs总含量范围在32.3 ng.g-1-241 200 ng.g-1,平均含量80 447.4 ng.g-1。

PAHs on the Environmental Impact of Soil Investigation and Reflection

To Xinyu steel city as an example, its soil PAHs content in the quantitative analysis carfled out to study the characteristics of their distribution, preliminary study of its pollution levels, PAHs and soil pollution prevention, to reduce the pollution to crops suggested. Of typical regional soil samples, may be high on the eight kinds of cancer-causing polycyclic aromatic hydrocarbons （PAHs） ：benzo a ] anthracene （4）, Qu, benzo b] fluoranthene （4）, benzo k ] fluoranthene （4）, benzo a ] pyrene （ 5 ）, dibenzo a, h ] anthracene （5）, benzo ghi ] perylene （6）, and indene （1,2,3-cd） pyrene （ 5 ）, the use of high-pressure liquid color Miriam ＆ P method, the analysis of measured results showed that 8 kinds of soil samples the total content of PAHs in the range of 32.3 ng·g^-1- 241 200 ng· g^-1 ,the average level of 80 447.4 ng · g^-1.
