Why should I be concerned about exposure to lead?
Childhood lead poisoning is a serious but preventable public health issue. Lead is a toxic metal that can cause learning and behavior problems, and delay physical growth and mental development. A blood test is available to measure the amount of lead in your blood and to estimate the amount of exposure to lead. This site provides data on blood lead testing and on elevated blood lead levels among Washington children.
- A change in blood lead levels from less than 1 µg/dL to 10 µg/dL is associated with a loss of six or seven IQ points. (Lamphear et. al. 2005, Cainfeld et. al. 2003).
