Lead and Tobacco Smoke Exposure Linked to Child ADHD
Children who are exposed to lead and tobacco smoke are eight times more likely to develop attention deficit hyperactivity disorder (ADHD), reports the Cincinnati Enquirer.
“Tobacco and lead exposure together seem to have a synergistic, negative effect,” said Dr. Tanya Froehlich, lead author of the Cincinnati study.
Eliminating childhood exposure to lead and tobacco smoke could cut the incidence of ADHD in the U.S. by more than a third.
Other studies have shown that both lead and tobacco smoke interfere with the function of dopamine, a chemical that helps transmit nerve signals in the brain.
Frehlich says that we need to increases public health efforts to protect children from exposure to lead and environmental tobacco smoke. A home air cleaner will help to eliminate both of those toxins from the indoor environment.
