In vivo genotoxicity of the pyrethroid pesticide beta-cyfluthrin using the comet assay in the fish Bryconamericus iheringii.

Environmental pollution by pesticide residues is a major environmental concern due to the extensive use of these substances in agriculture. The insecticide beta-cyfluthrin is a synthetic pyrethroid widely used in agricultural and other domestic activities. The aim of the present study was to assess the genotoxic effects of a sublethal exposure of the fish Bryconamericus iheringii (Characidae) to a commercial formulation of beta-cyfluthrin using the comet assay.
