• Description:
  This study estimated exposures to nano-size titanium dioxide (TiO2) while spraying and sanding a commercially available paint. The National Institute for Occupational Safety and Health (NIOSH) recommended exposure limit (REL) is eight times lower for ultrafine TiO2 (0.3 mg/m3) compared to fine TiO2 (2.4 mg/m3), as time-weighted average concentrations for up to 10 hours per day during a 40 hour workweek. Ultrafine includes nanoparticles. Air samples were collected while a tradesperson performed the tasks in an environmentally controlled chamber. Dust capture during sanding was provided by a dust collection bag or local exhaust ventilation attached to a high efficiency vacuum. Personal and bystander exposures were characterized using particle counts, airborne mass concentrations, and electron microscopy. See abstract: http://bit.ly/2vntBK0. [Description provided by NIOSH]
