• Description:
  As previously reported, the National Institute for Occupational Safety and Health (NIOSH) has been analyzing dust samples from areas that received volcanic ashfall to determine the level of free crystalline silica that they contain. Crystalline silica - the cause of the disease silicosis - can occur in several forms: quartz, cristobalite, and tridymite. Several techniques to identify and quantitate crystalline silica have confirmed the presence of quartz and cristobalite, at levels of about 2% and 4% of the respirable (<10 microm) fraction, in settled-dust samples collected at Ellensburg, Yakima, and Spokane, Washington. Questionnaires designed to study symptoms in the general population that could possibly be related to the ashfall were distributed the week beginning June 2 in Moses Lake, Washington, by a team of epidemiologists from the local and the state health departments and from CDC. A preliminary analysis of the questionnaires is now available. [Description provided by NIOSH]
