某退役焦化厂地块土壤污染状况初步调查分析

以某退役焦化厂地块为调查对象,通过资料搜集、现场踏勘,初步布设22个土壤采样点、7口地下水采样井进行调查。结果表明:因生产历史中跑冒滴漏、粗放管理等问题,机修车间、炼焦熄焦区、原煤及焦炭堆场区区域土壤中石油烃、苯并[a]蒽、苯并[b]荧蒽、苯并[a]芘、茚并[1,2,3-cd]芘均存在超标现象,需开展详细调查及风险评估。

Taking the plot of a decommissioned coking plant as the object of investigation,22 soil sampling points and 7 groundwater sampling wells were preliminarily arranged for investigation through data collection and site survey.The results showed that due to the reasons of leakage,leakage and extensive management in the production history,petroleum hydrocarbons,benzo[a]anthracene,benzo[b]fluoranthene,benzo(a)pyrene,indeno(1,2,3-cd)pyrene have exceeded the standard in varying degrees,so a detailed investigation and risk evaluation need to be carried out in the next stage.
