lead poisoning - History, Symptoms and effects, Biological role, Occurrence, Measurement, Treatment, Famous cases of lead poisoning


A disorder of children acquired by swallowing or inhaling lead, which is present in the environment in paint, car exhaust fumes, and air and water contaminated with industrial waste. High levels of lead in the blood result in brain, liver, and kidney damage, and lead is deposited in the bones, affecting their growth. There is mounting evidence that even low levels of lead can impair childhood development and lower IQ.
