Laser Printer and Toner Cartridge (Ultrafine Particle Emissions) — household safety profile
Moderate riskLaser printers emit ultrafine particles (UFPs <100nm), volatile organic compounds (styrene, benzene, toluene), and semi-volatile organic compounds during printing.
What is this product?
Laser printers emit ultrafine particles (UFPs <100nm), volatile organic compounds (styrene, benzene, toluene), and semi-volatile organic compounds during printing. Toner powder contains carbon black (IARC Group 2B), styrene-acrylate copolymer, iron oxide, and silica. UFP emissions from laser printers are comparable to cigarette sidestream smoke in terms of particle count. High-volume printing in poorly ventilated offices creates significant occupational exposure.
