2011-2-1  Cadmium and Zn levels are highly correlated with moderate to high levels in the soils directly downstream of the Hg mine tailings. The main contamination source for Cd and Zn in Wanshan is therefore also probably the mine tailings as such chalcophile elements are associated with the cinnabar ore.
