| Abstract: | Biphenyl was found to be converted to mutagenic compounds by UV irradiation with a high-pressure mercury lamp in nitrate aqueous solution under neutral conditions. The mutagenicity of the reaction mixture increased in proportion to the nitrate ion concentration. The most mutagenic product was dinitro dihydroxy biphenyl, and the main products in this reaction were 2-hydroxy-3-nitrobiphenyl and 4-hydroxy-3-nitrobiphenyl. |
