ABSTRACT
Occupational exposure to volcanic ash from Mount St. Helens continues during the salvaging of trees in the high dust blow-down area of Washington. We studied the effects of volcanic ash exposure on the level of humoral inmune factors IgG, IgA, IgM, C3, C4, and ANA (antinuclear antibody) in a group of volcanic ash-exposed loggers shortly after the major eruption and one year later. Comparisons with similar levels in nonexposed, similarly employed, matched loggers were made. C3 and C4 levels were significantly lower at both time periods in the exposed loggers when compared to the reference group. No differences between groups were observed at either time period for the inmunoglobulin levels or ANA. The exposed loggers did show a marked decrease (not seen in the reference group) in serum IgG levels after 1 yr of exposure to the volcanic ash. They likewise showed a significant mean increase in IgA, while the reference group had a mean increase in IgM after 1 yr. These data suggest that exposure to volcanic ash may affect humoral inmunologic parameters(AU)
