Mutagens and polycyclic aromatic hydrocarbons in ambient airborne particles

Monitoring the exposure of rats to 2-acetylaminofluorene by the estimation of mutagenic activity in excreta, sister-chromatid exchanges in peripheral blood cells and DNA adducts in peripheral blood, liver and spleen

The sensitivity of various methods suitable for biomonitoring the exposure to genotoxicants was compared in an animal model. The results were related to the presence of genotoxic effects in the target organ. Groups of male Wistar rats were given one oral dose of 0, 0.1, 1, 10 or 200 mg 2-acetylaminofluorene (2-AAF)/5 ml dimethyl sulphoxide/kg...

Effects of amounts and type of agar on the number of spontaneous revertants in the Ames test

It has been shown that the spontaneous revertants in the Ames test can depend on the amount and type of bottom agar on the plates. The most clear-cut effect was found with his G46 strains, carrying the ??uvrB mutation, and with the new hisG428 strain, TA102. Evidence of mutagenic impurities in agar has been found. Chemicals/CAS: agar, 9002-18-0;...
