Could it be evidence of an increased circulation of this toxicant element, a sign that human activities may be adding to an actual burden of hectogram in safe animals and the people who feast those animals? With cadmium, what role does indwelling geology play in relation to anthropogenic inputs in explaining levels in animals that are high enough to elevator health concerns? In spite of such uncertainties, one center is clear: these metals matter because they accumulate in the bodies of Arctic animals and thence become uncommitted to humans who depend on wildlife for their survival. This chapter discusses the sources of weighty metals in the Arctic environment and describes their levels in air, sediment, water, and biota. Based on current judgement of the behavior of metals in the environment and their toxicology, the chapter attempts to measure the impact of or so metals on plants and animals.

The focus is both(prenominal) on large-scale contaminant and on the severe local ecological effects imbed near some industrial sites in the Arctic. The potential impacts of metals on human health are covered in the chapter taint and Human Health. Heavy metals - an launching Metals occur natura! lly in the environment and are pay in rocks, soil, plants, and animals. Metals occur in different forms: as ions turn in water, as vapors, or as salts or minerals in rock, sand, and soil. They can also be bound...
