The results of short-term genotoxicity/mutagenicity tests on Salmonella typhimurium did not show the presence of genotoxic compounds in drinking water samples (neither nonconcentrated nor concentrated). The differences between prokaryotic and eukaryotic cells can affect the sensitivity to a variety of substances. Gene conversion frequences and recombination events in Saccharomyces cerevisiae (Zimmermann test) were also not increased after exposure to water samples.
Since the statistically significant results of the
comet assay revealed the presence o
