Diesel oil can be a source of contamination in aquatic environments, mainly as a result of spills. The effects of the water-soluble fraction of diesel (WSF) on Prochilodus vimboideswere assessed. Fish were exposed to three different WSF dilutions for up to 96 h and were compared to a control group. Damages in the fragments of DNA were analyzed using the Comet assay. The presence of erytrocyts abnormalities was assessed by micronucleus test. Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activity and the accumulation of copper in gills were also analyzed. Fish exposed for 96 h had higher rates of damage than those exposed for 24 h. There was no significant difference regarding the presence of micronuclei between exposed and control fish...

The high toxicity of diesel components makes oil spills a threat to the biota in coastal marine environments. The genotoxic effect of the diesel water-soluble fraction (DWSF) on Hippocampus reidi (Ginsburg, 1933) was assessed. Fish were exposed to three different DWSF dilutions for up to 96 hours, and genotoxicity was analyzed using the micronuclei test and the comet assay. The micronuclei test revealed no significant differences between any of the DWSF dilutions and the control in the 24-hours period; however, micronuclei increased in fish exposed to 1:500 and 1:100 DWSF dilutions for 96 hours. For all dilutions, there was an increase in micronuclei in fish exposed for 96 hours when compared to those exposed for 24 hours. The tested dilutions increased...
