Lead poisoning is a serious and sometimes fatal condition. It occurs when lead builds up in the body. Lead is a highly toxic metal and a very strong poison. It is found in lead-based paints, including paint on the walls of old houses and toys.
Drinking water is another potential source of lead exposure. Lead is rarely found in natural water sources, but it can enter drinking water as it travels through pipes containing lead. Homes built before 1986 are more likely to have lead pipes, fixtures, and solder. But even the lead-free plumbing found in newer homes may contain some lead.
