Soil contamination by heavy metals occurs from abandoned mining waste, landfill leachate, improper treatment of industrial wastes, industrial activities, accidental spills, etc. Common heavy metals contaminants are lead, cadmium, copper, cadmium and mercury. The contamination often affects a large volume of soil and the groundwater resources, posing a significant threat to human health and the environment. Over 2,000 heavy metals contaminated sites have been identified in Canada. Soil contamination by radioactive isotopes can result from nuclear waste, nuclear plant accidents and nuclear weapons.
