The US Department of Health and Human Services promoted October 20-27, 2019 as national lead prevention week. As of 2017, pediatricians reported that more than half a million US children had lead poisoning (AAFP, 2019).
The poisonous effects of lead have been documented for over 2,000 years. It is an environmental toxin whose effects are totally preventable; it has no biological role in the human body. Lead causes irreversible brain damage, especially in children. It affects numerous organs, such as the heart and kidneys, and influences behavior and cognition measured by IQ scores and other tests. Researchers have postulated that lead poisoning contributes to higher rates of impulsive behavior, attention deficit disorders, and poorer ability to process information. Nonetheless, the law does not require testing of all children for dangerous lead levels.
