NIOSH Current Intelligence Bulletin on Occupational Exposure to Titanium Dioxide

A few days ago, NIOSH released Current Intelligence Bulletin 63: Occupational Exposure to Titanium Dioxide which looks at currently available scientific data on the toxicity of titanium dioxide (including engineered nanoparticles of this substance), and describes exposure monitoring techniques, exposure and control strategies, and research needs. This report only addresses occupational exposures by inhalation.In the report, the authors outline the agency's suggestions for exposure levels that will help workers avoid long-term problems. The report recommends that nanoscale titanium dioxide should be considered a potential occupational carcinogen at this time.
