Because of the importance of monitoring to the protection of such a large number
of workers, numerous analytical methods have been developed for the analysis of
crystalline silica via three main government agencies. The high incidence of
mine-related illnesses and hazards has historically been the driving force for
establishing medical, health, and safety programs in government and industry. To
address hazards related to toxic substances and their identification in the
western region of the United States, the Occupational Health Field Station (Ft.
Douglas, UT) of the U.S. Public Health Service (PHS) in the 1940s provided
industrial hygiene analytical support. This support function eventually became a
part of NIOSH.
