Volcanic ash samples obtained after the May 18, eruption of Mount St. Helens, Washington, were analyzed for organic compounds. Several n‐alkanes, fatty acids, dicarboxylic acids, alcohols, phenols, aldehydes, aromatic acids, aromatic and polycyclic aromatic hydrocarbons and chlorinated aromatic compounds were identified by GC‐MS. Pyrolysis of plants and soil organic matter is the most probable source of these compounds.
