Inhalation Toxicity of a Smoke Containing Solvent Yellow 33, Disperse Red 9 and Solvent Green 3 in Laboratory Animals

The repeated-dose inhalation toxicity of a smoke containing a mixture of three dyes was tested in female mice, rats and guinea pigs. The green component dye (Solvent Green 3) was retained in the lungs. Particularly in the rats marked collections of alveolar macrophages were found. In the same species several other adverse findings were noted: these included adenocarcinomas of the breast in the high-dose group and a dose-related incidence of biliary hyperplasia. Fatty change was noted in the livers of the test-group mice. A large proportion of the high-dose guinea pigs died during the exposure period, for which reason exposure was stopped early in that group, otherwise the guinea pigs were little affected. However, all test groups of all species showed reductions in growth during the exposure period.
