摘要:
分析南通某搬迁化工厂区土壤中16种优控多环芳烃(PAHs)污染物的含量特征及污染水平。结果表明,车间和仓库土壤中多环芳烃总量为200-300 ng/g,在南通市耕地土壤污染水平范围内。停车场土壤中PAHs含量为3435 ng/g,污染水平高于普通耕地,与交通干线两侧土壤相当,土壤中PAHs以4环及4环以上PAHs为主,为汽车尾气污染,若继续用于道路或停车场等功能无需进行PAHs修复。

Analysis of the Sources of Polycyclic Aromatic Hydrocarbons in Surface Soil of a relocated Chemical Industrial
Abstract:
The concentrations and pollution levels of 16 polycyclic aromatic hydrocarbons (PAHs) in the soil of a relocated chemical industry of Nantong were studied. The results showed that the PAHs concentrations of workshop and warehouse soils are in the range of 200-300 ng/g, within the PAHs pollution level of farmland soil of Nantong City. PAHs concentration of the parking lot soil is 3435 ng/g. The pollution level is higher than the normal farmland, and comparable to the PAHs level of the soil of transportation routes. The PAHs pollution is mainly come from automotive exhaust pollution and the main pollutants are PAHs with 4 or more than 4 rings. If the parking lot zone continues to be used for roads or parking lot, PAHs remediation is not needed.
