Comparative genetic activity of samples collected from two different urban waste incinerators
Incineration of industrial and urban waste materials is an important problem for the environmental contamination and therefore for human health. Environmental contaminants spread by urban incinerators can contain a complex mixture of toxic compounds such as dioxin, benzofurans, alogenate acids. It is important to evaluate the genetic damage induced by complex mixtures widespread in the environment. In the present work, the genotoxic activity of samples obtained from the urban incinerator of Florence was analyzed. The results were compared with those obtained with samples drawn from the urban Snamprogetti incinerator of Schio (Vicenza), where halogenated acids contained in the smoke are neutralized with the lime wash in a salification column. Samples were tested using prokaryotic (Salmonella typhimurium TA98, TA100 and TA102 strains) and eukaryotic (Saccharomyces cerevisiae, D7 strain) microorganisms. These systems permit one to obtain rapid, reproducible and reliable results in order to evaluate the genotoxic activity of substances present in the environment.
