安徽北部某焦化厂场地土壤和地下水环境调查与风险评估

Soil and Groundwater Environment Investigation and Risk Assessment of a Coking Plant Site in Northern Anhui Province

以安徽省某焦化厂场地为研究对象,对厂区设置的84个土壤监测点和22口地下水监测井进行钻探和采样,共采集了373件土壤样品和42件地下水样品。本研究分析了场地主要污染区域和影响因素,得出场地土壤和地下水中的主要关注污染物为苯和多环芳烃。其中,土壤中苯的浓度范围为0.05~465mg/kg,苯并(a)芘的浓度范围为0.1~707mg/kg;地下水中苯的最大浓度为10.2mg/L,萘的最大浓度为11.5mg/L。

Taking the site of a coking plant in Anhui Province as the research object, drilling and sampling were carried out on 84 soil monitoring points and 22 groundwater monitoring wells set up in the plant, and 373 soil samples and 42 groundwater samples were collected. This study analyzed the main pollution areas and influencing factors of the site, and concluded that the main pollutants in the soil and groundwater of the site are benzene and polycyclic aromatic hydrocarbons. Among them, the concentration of benzene in the soil ranges from 0.05 to 465 mg/kg, and the concentration of benzo(a) pyrene ranges from 0.1 to 707 mg/kg. The maximum concentration of benzene in groundwater is 10.2 mg/L and the maximum concentration of naphthalene is 11.5 mg/L.
