Laser printers emit worrisome dust, study finds - CTV.ca
Office workers may be breathing in dangerous dust emitted from laser printers, finds a disturbing new study from Australian researchers.
The researchers found that certain printers release tiny particles into the air that could pose 'a significant health threat' when inhaled into their lungs.
The researchers didn't analyze the chemical makeup of the particles but think that they come from the toner, the ultrafine powder used in laser printers instead of ink. They found that the printers emitted more dust when the toner cartridge was new, and when the printers were used for printing graphics, which require greater amounts of toner.------------------------------------------- posted 7:01 AM :: reference link ::
