Ecological risk and source analysis of soil heavy metals pollution in the river irrigation area from Baoji, China.

Due to various human activities, soil quality under different land use patterns is deteriorating all over the world. This deterioration is very complex in the river irrigation area and is caused by multi-point and non-point source pollution and seasonal variation. Therefore, the characteristics and...
