Abstract

Piscine micronucleus assay and the evidence of environmental degradation: the case of catfish from Brazilian tropical estuaries Bioensaio de micronúcleo em peixes e evidências de degradação ambientai: o caso dos bagres de estuários tropicais brasileiros

Evaluation of the genotoxicity in fish erythrocytes to diagnose the water quality of two Amazonian estuaries using the micronucleus test and comet assay

“…The potentially harmful effects of many substances found in aquatic environments have been the focus of an ample range of research due to the potential consequences for both aquatic organisms and human beings (Costa et al, 2008;Ghisi et al, 2010;Martins and Costa et al, 2015;Rocha et al, 2016;Oliveira, et al, 2020;Santana, 2020), given that many of the pollutants discharged directly or indirectly into these environments originate from human activities and, while some substances being biodegradable, many others are not (Robert, 2008). A number of other studies have also shown that the degradation of the aquatic ecosystems exposed to industrial waste may lead to a decline in the abundance of commerciallyimportant sh species, resulting in social and economic problems for the local communities (Kennish, 1985;Blaber, 2000).…”
