Abstract |
Three sets of combustion emissions were selected for evaluation: automotive diesel exhaust, woodsmoke, and a coal combustion emission. Each sample was tested in the Salmonella mutagenicity assay according to standard protocol (plate incorporation) and spiral assay techniques. Two assays demonstrated the following: (1) Diesel exhaust was generally the most mutagenically potent sample in both assays. (2) Samples were more mutagenic on rev/microgram basis in the spiral assay, especially when metabolic activation was added. (3) The spiral assay required 1/20 the sample mass of the standard assay to test equivalent doses. (4) Dichloromethane extracts of the complex mixtures could be tested for mutagenicity in the spiral assay. |
