Assessment of water quality and genotoxic impact by toxic metals in Geophagus brasiliensis

Abstract: This study used the pearl cichlid Geophagus brasiliensis as a bioindicator to survey the health of the aquatic environment on four sites (P1, P2, P3 and P4) of the Mumbuca stream located at Monte Carmelo/MG, Brazil. The selection of different sites was made with reference to the gradient of urban activity and via physicochemical and biological evaluation of water quality and genotoxicity. The water quality index was classified as 'good' for P1 and P4, regular in P2 and 'poor' for P3. The micronuclei (MN) frequ… Show more

“…Species of the genus Geophagus have been used as indicators of negative impacts on aquatic ecosystems, especially rivers with little or no riparian vegetation and anthropically altered environments, since their tolerance to hypoxia and their generalist habit (Caetano et al, 2016;Cetra and Ferreira, 2016;Morais et al, 2016;Gomes et al, 2016), favor colonization in these environments. In this way, if they have available food, these individuals can perform other essential activities, such as growth and reproduction.…”

“…O uso de organismos como bioindicadores torna-se importante para avaliar o real risco de exposição a poluentes, especialmente porque esses organismos são avaliados em seu habitat natural (MORAIS et al, 2016). Dentre as plantas superiores, o Allium cepa L. (cebola) tem sido indicado como um importante organismo-teste de mutagenicidade, pois suas raízes crescem rapidamente e são bastante sensíveis a mudança ambiental.…”

“…(1970). Desde então, eles têm demonstrado uma plasticidade enorme na utilização em testes de genotoxicicidade e clastogenicidade para uma série de substâncias como os recém-elaborados nanomateriais (GONZALES; KIRSCH-VOLDERS, 2016); efeito da exposição à agrotóxicos em seres humanos (JACOBSEN-PEREIRA, et al, 2018;RUIZ-GUZMÁN et al, 2017) e em aves nativas (SOUTO, et al, 2018); e até no biomonitoramento ambiental para uma substância muito conhecida mas pouco estudada como potencial poluidora do meio ambiente como é o caso da cocaína (PAROLINI et al, 2017) ou para uma série de poluentes lançados como efluentes (CAMPOS et al, 2015;MORAIS et al, 2016); poluição atmosférica (CAMPOS et al, 2016); utilização de larvicidas no combate ao mosquito Aedes aegypti (PEREIRA et al, 2016), dentre outros.…”
