Temporal variations of heavy metals in sediment, soil and …
Possible reasons for difference of pollution levels and elements are mainly 1) Most of the Pb-Zn mines in China are mined by underground infill mining, airfield mining and natural segmental crumbling method, which release large amounts of dust, harmful gases, wastewater and depleted rock from the raw ore during mining [23,41].
