中文摘要:
      研究对比了山东省不同类型污染企业周边土壤中16种多环芳烃(PAHs)的污染水平,结果表明:化工、钢铁、焦化企业周边土壤中ΣPAHs范围分别为414 μg/kg~804 μg/kg、1 230 μg/kg~1 945 μg/kg和776 μg/kg~1 299 μg/kg,土壤中PAHs成分谱轮廓相似,4~6环PAHs占比普遍高于2~3环。特征比值法源解析表明,PAHs主要来源于煤、焦炉、木材等的不完全燃烧。企业周边土壤PAHs污染与企业产业结构有关,钢铁、焦化、石化等大量消耗化石燃料的企业周边土壤中10种PAHs的毒性当量浓度TEQBap超标06倍~38倍,而高分子化工、精细化工、农药化工等企业周边土壤受PAHs污染较轻,均满足荷兰土壤质量标准。
英文摘要:
      The pollution of 16 PAHs in soils around different type of enterprises in Shandong province were studied. Results showed that the concentration range of ΣPAHs in soils around chemical enterprise, iron and steel enterprise, coking enterprise and petrochemical enterprise were 41.4 μg/kg~804 μg/kg,1 230 μg/kg~1 945 μg/kg and 776 μg/kg~1 299 μg/kg, respectively. The proportion of PAHs with 4 to 6 rings were more than that with 2 to 3 rings. Results of source apportionment by characteristic ratio method showed that PAHs were mainly from the incomplete combustion of coal, coke and wood, etc. PAHs pollution in soils around the enterprises was related to the industrial structure. The TEQBap of 10 PAHs in soils around iron and steel enterprise, coking enterprise and petrochemical enterprise exceeded the standard limit by 0.6~3.8 times. The PAHs pollution was slight in soils around polymer chemical industry, fine chemical industry and pesticide chemical industry, and the concentrations all met Dutch soil quality standard demand.
