Lead is devastating to the human body, inhibiting oxygen and calcium transport and altering nerve transmission in the brain.
Most lead poisoning occurs when people swallow lead paint chips or breathe in lead dust.
Lead Poisoning in Children Studies show that even low concentrations of lead can cause permanent damage including reduced IQ, learning disabilities, and shortened attention span. Some scientists believe that low-level chronic lead exposure in childhood can alter secretion of the human growth hormone, stunting growth and promoting obesity. Even low lead doses are a concern for children, since continuing exposure can add up to a significant dose over time. Children's Special Vulnerability Children are in double jeopardy from lead because their highest potential for exposure occurs when they are most vulnerable. Unfortunately, most children do not present overt symptoms of poisoning.
