Interesting Fact # 605 – Printers

Office printers may be as harmful as cigarettes.

(Laser printers emit tiny particles of toner that can cause respiratory irritation to more chronic illnesses and the same is true for photocopiers. A major Danish study on copier pollution found that ozone and other chemicals could exceed the ’occupational exposure limit’. Users can be exposed to Ozone, Selenium, Cadmium sulphide, Nitrogen oxide, Carbon monoxide and of course Toner particles.)
