The proof of “indoor air quality”, designed to protect and improve the health and safety of workers, The environment in which he lives and works a continuous gas exchange through breathing; this makes the respiratory system main entrance of air pollutants. The indoor pollutants are numerous and originate from different sources.
It is well known that photocopiers and laser printers are equipment that emit several chemicals (ozone, solvents, toner dust). During the printing and photocopying processes occurring chemical and physical processes complex.
This work was the main objective the sensing emission of volatile organic compounds, formaldehyde and ozone from laser printing devices.
