山东省表层土壤重金属来源及风险评估
发布时间：2018-11-06 14:47
【摘要】：本文搜集2005~2016年最新发表的关于山东省土壤重金属污染的科研论文,分析不同区域8种重金属的含量分布及来源,综合评估其可能存在的生态风险。研究表明聊城和黄河口区域重金属浓度最高,而滨州、德州、小清河流域等区域重金属浓度相对较低,且来源解析表明其主要来自于交通运输、金属冶炼和化石燃料燃烧。各重金属中,Hg、Cd的生态危害系数最高,属于中等或较强污染程度,但生态风险总体上处于较低轻度水平。
[Abstract]:This paper collected the latest scientific research papers on soil heavy metal pollution in Shandong Province from 2005 to 2016, analyzed the distribution and source of 8 heavy metals in different regions, and comprehensively evaluated the possible ecological risks. The results show that the concentration of heavy metals in Liaocheng and Huanghe estuary is the highest, while that in Binzhou, Texas and Xiaoqing River basin is relatively low, and the source analysis shows that heavy metal concentration mainly comes from transportation, metal smelting and fossil fuel combustion. Among the heavy metals, the ecological hazard coefficient of Hg,Cd is the highest, which belongs to moderate or strong pollution degree, but the ecological risk is generally in the low and light level.
