Metal toxicity

Metal toxicity or metal poisoning is the bad effect of certain metals in certain forms and doses on life. Almost all heavy metals are toxic. But, some heavy metals like iron are essential. Elements that we need in our body may also be toxic when in very high doses may be toxic.
Testing and treatment for poisoning.
People are always being exposed to metals in the environment. Medical tests can find metals in our body but does not show that a person is poisoned. Metal screening tests should not be used unless there is reason to believe that a person has had been exposed to huge amounts of metals.
A treatment for metal poisoning may be chelation therapy, which is a technique which involves the giving of chelation agents to the patient to remove metals from the body.
