Genotoxic and mutagenic effects of polluted surface water in the midwestern region of Brazil using animal and plant bioassays

Abstract: This study aimed to evaluate DNA damage in animal and plant cells exposed to water from the Água Boa stream (Dourados, Mato Grosso do Sul, Brazil) by using bioassays, and to identify the chemical compounds in the water to determine the water quality in the area. Through the cytotoxicity bioassay with Allium cepa, using micronucleus test, and comet assay, using Astyanax altiparanae fish, the results indicated that biological samples were genetically altered. Micronuclei were observed in erythrocytes of A. altip… Show more

“…A micronucleus may arise from a whole lagging chromosome or an acentric chromosome fragment detaching from a chromosome after breakage which does not integrate in the daughter nuclei [39]. Pollution of the environment with various chemical American Journal of Plant Sciences agents increases the frequency of micronucleus formation in both plants and animal cells, increasing the ecotoxicological risk [40] [41]. In accordance with Gömürgen (2005), such genetic damages like micronuleus may have clastogenic effect of their inducers [23].…”

“…A cidade de Dourados é a maior entre aquelas que ocorrem total ou parcialmente dentro desta bacia, com aproximadamente 215 mil habitantes e a base da economia da região é a agricultura e a pecuária (Gonçalves et al, 2010;Paula et al, 2013). A bacia do rio Dourados é caracterizada nas suas proximidades por várias atividades agroindustriais, que acabam gerando contaminantes que são escoados para o ambiente aquático (Dourado et al, 2016).…”
