Ascertaining the pollution, ecological risk and source of metal(loid)s in the upstream sediment of Danjiang River, China

The study on metal(loid) contamination of sediment in river upstream is lacking. The content, pollution, risk and source of ten metal(loid)s (As, Co, Pb, Cu, Ni, Cr, V, Mn, Ba, and Zn) in the upstream sediment of Danjiang River, China were investigated to explore the environmental quality of headwat...
