Quote:As little as a few specks of lead in the water children drink or in flakes of paint that come off the walls of old houses and are ingested can change the course of a life. The amount of lead dust that covers a thumbnail is enough to send a child into a coma or into convulsions leading to death. It takes less than a tenth of that amount to cause IQ loss, hearing loss, or behavioral problems like attention deficit hyperactivity disorder and dyslexia. The Centers for Disease Control (CDC), the government agency responsible for tracking and protecting the nation's health, says simply, "No safe blood lead level in children has been identified."It’s Not Just Flint.
