摘要
本研究以江西省某退役化工厂遗留地块为研究对象,调查场地土壤有机污染物含量,筛选污染源,通过单因子指数法和内梅罗综合指数分析法对场地生态风险进行评价。结果表明:该场地存在极其严重的污染,其中苯并(a)蒽、苯并(a)芘在整个土壤层的污染最为严重;其次为茚并(1,2,3-cd)芘,在3.0m以上污染严重;2,4-甲基苯酚仅在表层0.2 m处存在超标;苯并(g,h,i)芘在0.2,2.0,3.0 m处略有超标,各区域污染程度为原油储罐区>苯酚车间>混炼胶车间>炭黑仓库。因此需要针对各个区域的污染特点,尽快对该地块进行污染治理工作以满足后续的开发利用需求。
The development of chemical industry is beneficial to social economy.With the decommissioning of chemical plants,organic pollution of the sites is also restricted.In this study,a decommissioned chemical factory in Jiangxi Province was investigated,organic pollutants were test and their ecological risk was evaluated by single factor index and Nemerow index.Results showed that there were extremely serious organic pollutants in the site,among which benzo(a)anthracene and benzo(a)pyrene were the most serious in the whole soil layer,followed by ninhydrin(1,2,3-cd)pyrene,which was seriously polluted at more than 3.0m;2,4-methylphenol was found to exceed the standard at only 0.2m in the surface layer;benzo(g,h,i)pyrene slightly exceeded the standard at 0.2 m,2.0 m and 3.0 m,and the pollution degree in each area was:crude oil storage area>phenol workshop>mixed rubber workshop>carbon black warehouse.Therefore,according to the characteristics of pollution in each region,pollution control should be carried out as soon as possible to meet the needs of subsequent development and utilization.
