title: Mutagenicity of coal-pyrolyzed products and their photochemical reaction products with nitrogen oxides in Salmonella typhimurium TA98 and TA100.
abstract: The chemical class separation of coal-pyrolyzed products and the photochemical reaction of these fractions with nitrogen oxides in the experimental chamber, and the application of a short-term mutagenicity test were investigated. The altered products from the fraction hydroxy polycyclic aromatic compounds in a simulated atmosphere containing a small volume of nitrogen oxides under irradiation with a xenon lamp were the most potent mutagenic fraction among all the fractions tested against Salmonella typhimurium, both TA98 and TA100, with or without S9.
