Lead is a powerful neurotoxin that causes irreversible damage to the brains of children. Because it damages the brain before it is fully developed, it has a particularly devastating effect on babies and children under the age of five, leading to neurological, cognitive, and physical disabilities later in life. Lead exposure in children after age 5, such as age 12, has also been linked to increased mental health and behavioral problems, crime, and violence. Older children suffer serious consequences, including kidney damage and an increased risk of cardiovascular disease, according to the report.Q&A: Lead Poisoningmicrosoftstart.msn.com Lead (Pb) Toxicity: What Are U.S. Standards for Lead Levels ...
