What it means
A group of metals that build up in the body and damage the nerves, kidneys, gut and blood. Common sources are old lead paint and dust, some water pipes, some imported remedies and cosmetics, certain fish (mercury) and workplace exposure. Children are most at risk from lead, which can harm the developing brain. Heavy metal poisoning is treated by removing the source and, when levels are high, with chelating drugs that bind the metal so it can leave the body in urine.
