The fungal degradation of polyaromatic hydrocarbons (PAH) in a contaminated soil from a hazardous waste site was evaluated in a pilot-scale study. As some PAH are known to be mutagens, the Tradescantia-micronucleus test (TRAD-MCN) was selected to evaluate the genotoxicity of the soil before and after fungal treatment. The genotoxicity test was conducted with Tradescantia clone 4430. Cuttings were exposed for 30 hours to different dilutions of soil extracts from the PAH-contaminated soil before and after fungal treatment. The results indicate that the Trad-MCN test has a potential utility for evaluating the efficiency of bioremediation of genotoxic soil contaminants.
