Printer pollution

That office stalwart - the printer - may be a source of air pollution and a potential health hazard, a CBC investigations team has found.

Office printers can release ultrafine particles, or UFP, that are so small scientists have only recently been able to measure them.

Researchers have raised concerns that tiny particles from sources such as printer toner, tobacco smoke, combustion soot, bacteria and mould could be absorbed into the lungs and cause eye, nose, throat and lung irritation.
