Over 40 Years of Lead Poisoning in Children
As of 2017, more than half a million US children have lead poisoning. For over 2,000 years humanity has documented the poisonous effects of lead. It is a preventable environmental toxin that has no biological role in the human body. Lead causes irreversible brain damage especially in children. Presently the law does not require testing of all children for dangerous lead levels. Compare this to PKU (Phenylketonuria).
