Airborne substances such as carbon monoxide (CO), and biproducts from fuels, solvents, glues, paints, thinners and pesticides can cause serious brain injuries. Some of these, such as carbon monoxide, are odorless and colorless, but cause brain damage and even death. 

 

Long-term exposure to these dangerous substances slowly damage the brain. Improper ventilation in the home and work place facilitate exposure.
