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.
Lead used to be very common in gasoline and house paint in the U.S. Children living in cities with older houses are more likely to have high levels of lead. Although gasoline and paint are no longer made with lead in them, lead is still a health problem. Lead is everywhere, including dirt, dust, new toys, and old house paint. Unfortunately, you cannot see, taste, or smell lead.
