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。
In order to make a well understand of heavy metal contamination in shandong,we collected some papers published in 2005-2016. The contamination level,distribution,source and risk assessment of heavy metal were discussed in this study. The results indicated that concentration in Liaocheng and Yellow River estuary were the highest,while in Bingzhou,Dezhou and Xiaoqing River Valley were the lower. Source identification indicated that the heavy metals were mainly from transportation,metal smelting and fossil fuel. Among all the 8 heavy metals,the risk of Hg and Cd were the highest,and the contamination level was low from the all province scale.
