TL;DR: The results indicate that the comet assay was a sensitive tool to detect DNA damage in subjects under the influence of an oil refinery, with marked genotoxic activity in the atmospheric environment.

TL;DR: The mutagenicity of interstitial water and organic extracts from the sediments in the Cadeia and Feitoria Rivers, RS, Brazil, were evaluated by Salmonella microsuspension bioassay using TA97a, TA98, TA100 and TA102 strains, in the absence and presence of S9 mix.

TL;DR: It became clear that the biological assays were of significant benefit in the diagnosis of risks of contamination of hydrographic basins by pollutants from urban non-point sources.

TL;DR: The microsuspension assay in Salmonella/microsome was sensitive to detect and identify different classes of airborne mutagenic compounds present in fine particulate matter in Porto Alegre city, showing that monitoring air quality with PM2.5 using this methodology is relevant.

TL;DR: Lichens and mutagenic biomarkers enabled the evaluation of air quality and the presence of environmentally-aggressive compounds and nitro compounds was detected through nitro-sensitive strains.
