How many workers are potentially exposed to nanoparticles?
NIOSH is unaware of any comprehensive statistics on the number of people in the U.S. employed in all occupations or industries in which they might be exposed to engineered, nano-diameter particles in the production or use of nanomaterials. Perhaps because of the relative newness of the nanotechnology industry, there appear to be no current, comprehensive data from official survey sources, such as the U.S. Bureau of Labor Statistics (BLS). The magazine SMALL TIMES has reported a partial figure. In a 2004 survey, it estimated that 24,388 people are employed in companies engaged only in nanotechnology. This total includes all people employed in those companies, not simply those engaged in research or manufacturing jobs that may involve exposure to nano-diameter, engineered particles. The survey did not include the number of people who may work in companies that engage in nanotechnology only as part of a larger corporate portfolio. The survey is expected to be updated this year, retaining
