Effect of anthropized water on eukaryotic organisms

O efeito da água antropizada sobre organismos eucarióticos

Abstract

This work explored whether anthropized environments have the potential to promote cellular alterations in eukaryotic organisms. Wild fish that are in constant contact with anthropized water were evaluated using the following variables: presence of nuclear alterations and micronuclei in erythrocytes using the Feulgen method; and tissue analysis of the gills and liver through histological sections using Hematoxylin and Eosin staining. Therefore, 200 individuals were analyzed over 24 months. The results show that these environments are promoters of significant changes in liver and gill tissue and induce nuclear changes in erythrocytes. The analyses were subjected to statistical tests at a significance level of 0.5%.
