Some office laser printers found to contribute nanoparticles to indoor pollution
A new study published in Environmental Science & Technology ("Particle Emission Characteristics of Office Printers") shows that certain laser printers commonly used in offices around the world emit nanoparticles into the air.
Lidia Morawska and Congrong He at the Queensland University of Technology and Len Taplin at the Queensland Department of Public Works, both in Brisbane, investigated the submicrometer particle emissions produced by each of 62 printers (from Canon, HP and Toshiba) used in office buildings and, based on the particle concentrations in the immediate vicinity of the printers, after a short printing job, the printers were divided into four classes: non-emitters, and low, medium, and high emitters. It was found that approximately 60% of the investigated printers did not emit submicrometer particles and of the 40% that did emit particles, 27% were high particle emitters.
