TORONTO — Some laser printers emit as much fine-particle pollution as cigarette smoke, which can lodge deep in people's lungs to pose a significant health threat, Australian researchers have found.
Some popular brand printers release so much toner into the air that the amount of fine particles in office air increases five-fold during work hours, and new toner cartridges and graphic-heavy printing projects further boost the amount of ultra-fine powder in the air.
