Abstract
Elemental Metals in Agricultural Soils along Two Tributaries of Chaohu Lake: Implication on Soil Erosion Caused Enrichment in Sediments
Highlights
As well known, some elements are essential to human body and play irreplaceable roles in the functioning of body organs, and all living organisms require varying amounts of metals (Lane and Morel, 2000)
Rice soil samples along two main tributaries of Chaohu Lake were collected to determine 30 metal elements which were compared with the data on the elements in surface sediments of Chaohu Lake to explore the impacts of soil erosion on the accumulation in the sediments
The results showed that the concentrations of most elements were less than their soil background values of Anhui Province, but Se, Sb, Sn, As, and Ba were greater than the corresponding background values
Summary
Some elements are essential to human body and play irreplaceable roles in the functioning of body organs, and all living organisms require varying amounts of metals (Lane and Morel, 2000). It will be toxic at higher concentrations, and certain metals can even lead to a wide range of toxic effects, such as carcinogenicity (Qu, et al, 2012b, Thomas, et al, 2009). Chronic exposure to those heavy metals and metalloids even at relatively low levels has adverse effects on human body health and other animals (Kamunda, et al, 2016, Qu, et al, 2012b, Tsai and Lee, 2013).
