Lead was previously believed to be a serious threat only when it caused physical damage. But now lead is recognized as a toxin for which there is no safe level, especially when it comes to small children. Even low concentrations in a child’s blood have been found to cause Attention Deficit Disorder, reduced IQ and anti-social behavior.
The World Health Organization (WHO) has done extensive research on the sources and effects of lead exposure and lead poisoning, and published a study on Childhood Lead Poisoning.
The Centers for Disease Control and Prevention (CDC) has started the Childhood Lead Poisoning Prevention Program, which aims to eliminate blood lead levels greater than 10 μg/dL in children.
The Lead Group, Inc. in Australia has published many articles regarding lead and lead safety, including Health Impacts of Lead Poisoning and a Childhood Lead Poisoning Risk Factor Questionnaire.
