草河口地区沉积物和土壤中铊的地球化学行为

Geochemical Behaviour of Thallium in Soils and Sediments of Chaohekou Region

通过对草河口地区二道坊河沉积物和土壤中铊的分析与研究表明，该区域土壤中铊的含量高于世界与中国土壤铊含量的值；铊的富集特征具有一定的特殊性，并且铊在土壤和沉积物中与其相应性质关系有较大差异；在该河流沉积物的条件下，游离氧化锰对铊富集起着重要作用。

The contents and geochemical behaviour of thallium were investigated in soils and sediments of Chaohekou region .The contents of thallium in soils in this region were higher than those in soils in the world and in other places of China. The geochemical behavior of thallium had definite particular characteristics, and there were some differences between soils and sediments.Free Ferro-oxides played a very important role in the fate of thallium in the researched sediments.
