Check out your favorite restraurant - the air freshener 
in the restroom may make you feel dizzy or short of breath. 
The last time you walked through a parking lot on a hot day, 
could you tell which cars had little air fresheners on the 
dash board with your eyes closed?

Under controlled conditions, we had groups of laboratory mice 
breath the fumes released by several types of air fresheners. 
We found scientific data demonstrating irritation of the eyes, 
nose, throat, and sinuses; difficulty breathing; asthmatic 
reactions, and changes in nervous system function(loss of balance, 
tremors, and convulsions). Several of the mice died as a  
result of breathing these chemicals.

The data demonstrate that some air fresheners release  
toxic (poisonous) chemicals which can irritate the airway 
and cause serious malfunction of the nervous system.
