Abstract
This report contains the results of an environmental mutagenesis research project carried out in the Parma district. Samples were collected from an industrial and urban solid waste incineration plant and from its surroundings. These samples were analysed for their genotoxicity. The D7 S. cerevisiae, and strains TA98 and TA100 of S. typhimurium were used as the test organisms. There was a wide variation among the samples, whether it was samples obtained from the various steps of the incineration process, or from within the metabolic or non‐metabolic activation analysis. The majority of soil samples from the surroundings of the incinerator demonstrated mutagenic activity. It is difficult to ascertain the origin of the various mutagenic components because of the presence of other possible pollution sources, e.g. pesticides. Nevertheless, it is possible to correlate the presence of the mutagenic substances with the prevailing winds, rain pattern, and atmospheric pressure.
