Mind that printer

New research from the Queensland University of Technology suggests that after testing more than 60 printing machines, almost a third emit potentially dangerous levels of toner into the air. Conducted in an open plan office, the test revealed that particle levels increased five-fold during working hours; the problem was worse when new cartridges were used, and when graphics and images required high quantities of toner.

The researchers have called on governments to regulate air quality in offices and want companies to ensure that printers are based in well-ventilated areas so that particles disperse.
