Inorganic lead is a malleable, blue-gray, heavy metal that occurs naturally in the Earth’s crust. Lead was one of the first metals used by humans and consequently, the cause of the first recorded occupational disease (lead colic in a 4th century BC metal worker). In 2012, U.S. production of lead was estimated at 1.6 million metric tons; primarily from secondary refining of scrap metal.

Lead poisoning is almost never a single event in which a child ingests harmful quantities of lead, gets sick, and must be rushed to the hospital. Instead, lead poisoning is an insidious, month-by-month accumulation of lead in a child's body. I have supervised 30,000 cases of child lead poisoning, and I have not seen a case of symptomatic lead poisoning for many years, Rosen says.

Children with dangerously high blood lead levels -- 45 micrograms/dL or more -- can be treated by chelation (pronounced key-LAY-shun). Chelation involves giving a child one of two drugs that quickly remove lead from the blood. Chelation can save the life of a child with acute lead poisoning. But it does not remove all lead from the body. Most ingested lead is stored in the bones and leaches back into the bloodstream -- and brain-- over time. Chelation stops lead poisoning from being life-threatening, Rosen says. Has damage already been done to the brain? Yes. Chelation does not reverse the adverse effects of lead on the brain. What it does do is save lives.

Lead enters the body primarily through inhalation and ingestion. Today, adults are mainly exposed to lead by breathing in lead-containing dust and fumes at work, or from hobbies that involve lead. Lead passes through the lungs into the blood where it can harm many of the body's organ systems. While inorganic lead does not readily enter the body through the skin, it can enter the body through accidental ingestion (eating, drinking, and smoking) via contaminated hands, clothing, and surfaces.
