Lead poisoning

Lead is a very strong poison. When a person swallows a lead object or inhales lead dust, some of the poison can stay in the body and cause serious health problems. A single high, toxic dose of lead can cause severe emergency symptoms. However, it is more common for lead poisoning to build up slowly over time. This occurs from repeated exposure to small amounts of lead. In this case, there may not be any obvious symptoms, but the lead can still cause serious health problems over time, such as difficulty sleeping or lowered IQ in children.

Lead is much more harmful to children than adults because it can affect children's developing nerves and brains. The younger the child, the more harmful lead can be. Unborn children are the most vulnerable.

Children get lead in their bodies when they put lead objects in their mouths, especially if they swallow the lead object. They can even get lead poison on their fingers from touching a dusty or peeling lead object, and then putting their fingers in their mouths or eating food afterward. Tiny amounts of lead can also be inhaled.

Testing shows that many children have too much lead in their blood. Overall, about 1 in 20 preschoolers have high levels of lead in their blood. Any child can be affected. Children living in cities or older houses are more likely to have high levels.
