Titanium Dioxide: A Changing Paradigm in Occupational Risk Management

A recently released NIOSH guidance document on handling titanium dioxide (TiO2) powders in the workplace is possibly the first to recommend separate occupational exposure limits for the same material based on particle size. This document reflects increasing attention to evaluating and mitigating risks of emerging hazards in the workplace before adverse health effects occur in workers. Read More >

Occupational Disease and Nanoparticles

In the September issue of the European Respiratory Journal, the first medical case series of workers with serious disease that the study authors associate with exposure to nano-sized particles has been published. Investigators Y. Song, X. Li, and X Du of the Chaoyang Hospital of the Capital University of Medical Sciences in Beijing, China, report on a series of seven previously healthy young women who developed serious heart and lung disease after working at a print plant exposed to a chemical "paste" mixture containing undefined "nanoparticles" of approximately 30 nanometers in diameter. Read More >
