As a heavy industrial city, Liuzhou has been facing a serious pollution problem. It is necessary to take steps to control and prevent environmental pollution wherever possible. Surface soil samples were collected from four communities in Liuzhou City, to determine the concentrations, distributions, sources, and toxicity potential of polycyclic aromatic hydrocarbons (PAHs) present. The mean concentrations of total PAHs in the surface soil are 756.43 ng/g for the heavy industrial area, 605.06 ng/g for the industrial area, 481.24 ng/g for the commercial-cum-residential area, and 49.93 ng/g for the rural area. Both the isomer ratio and principal component analyses for the PAHs prove that these pollutants originate mainly from coal, diesel, gasoline, and natural gas combustion. The pollution hierarchies and toxic equivalency factor of BaP prove that the city is subject to heavy pollution caused by industry, transportation, and daily human activities.
作为一个重工业城市，柳州一直面临着严重的污染问题。有必要在任何可能的情况下采取措施控制和防止环境污染。从柳州市四个社区采集了表层土壤样本，以确定存在的多环芳烃 (PAHs) 的浓度、分布、来源和毒性潜力。重工业区表层土壤中总多环芳烃的平均浓度为 756.43ng/g，工业区为 605.06ng/g，商住区为 481.24ng/g，农村地区为 49.93ng/g。多环芳烃的异构体比值和主成分分析都证明这些污染物主要来自煤炭、柴油、汽油和天然气燃烧。BaP 的污染层次和毒性等效因子证明，该市受到工业、交通和日常人类活动造成的严重污染。
