Growth of cells in culture treated with the soluble component of volcanic ash from Mount St. Helens.
Volcanic ash was collected immediately after the eruption of Mount St. Helens on May 18, 1980. This ash was extracted with water. The elemental composition of the extracted portion was determined by atomic absorption spectrometry. The aqueous extract was applied at high concentrations (up to 37.5 micrograms/ml) to non-confluent mixed cultures of mouse lung cells. Even after treatment for up to 10 days, cell number was typically unaffected by the ash extract. Cell viability was also unaltered, and no grossly observable changes were noted in the cells by light microscopy. We conclude that the water-soluble portion of the ash we tested does not markedly affect growth of the cells most at risk, those of the lung.
