Resumo: | Environmental research realized at Educandos basin (Manaus – AM), which includes several dwelling-places and Manaus Free Trade Zone (ZFM), to avail the impact of anthropogenic activity on local streams and potential influences over Rio Negro, at Manaus’ shoreline. It was determined pH, E.C., turbidity, temperature, TSS, anions (HCO3-, NO3-, F-, Cl-, SO42-) and dissolved metals (Ni2+, Pb2+, Cr3+, Cu2+, Fe2+, V+, Zn2+ e Al3+). Anions were measured by HPLC; metals, by ICP-OES; and remainder parameters by classic methods. All the analyzed parameters were altered at streams because of anthropogenic activity. Results showed Quarenta stream hadn’t had altered the quality standards of Rio Negro’s water. It was noticed a high degradation on the base level of Cachoeirinha and Mestre Chico streams, in which were found the highest levels of Cl-, F-, SO42-, E.C., pH e HCO3-. These parameters were higher than those obtained in last decades, indicating an increase in contamination by sewage. Places near ZFM presented high levels of Ni2+ e Al3+, arising from industrial waste. Levels for metals Pb2+, Cr3+, Cu2+, V+ were recorded below the permissible limits according to Resolution n.357/2005 – CONAMA in all spots, indicating a possible reduction on the emission of potentially toxic metals. |

Foi determinado o pH, C.E., turbidez, temperatura, SST, ânions (HCO3-,NO3-, F-, Cl-, SO42- ) e metais (Ni2+, Pb2+, Cr3+, Cu2+, Fe2+,V+, Zn2+ e Al3+). Mensurou-se os ânions por CLAE, os metais por ICP-OES e demais parâmetros por métodos clássicos. Constatou-se alteração de todos os parâmetros nos igarapés pela atividade antropogênica. Observou-se que o igarapé do Quarenta não alterou significativamente os padrões de qualidade da água na orla do Rio Negro. Observou-se elevada degradação da foz dos igarapés do Cachoeirinha e Mestre Chico com os mais elevados níveis de Cl-, F-, SO42-, C.E., pH e HCO3-. Estes parâmetros foram mais altos que em décadas passadas, indicando um aumento de contaminação por esgotos. Locais ao lado do PIM apresentaram altos teores de Ni2+ e Al3+, decorrente da emissão industrial. Os metais de Pb2+, Cr3+, Cu2+, V+ mantiveram-se adequados a legislação N° 357/2005 do CONAMA em todos os pontos de coleta, indicando possível redução da emissão de metais potencialmente tóxicos.EDUFU - Editora da Universidade Federal de Uberlândia2020-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos paresapplication/pdfhttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/5279410.14393/RCG217752794Caminhos de Geografia; Vol. 21 No. 77 (2020): Outubro; 209-219Caminhos de Geografia; Vol. 21 Núm. 77 (2020): Outubro; 209-219Caminhos de Geografia; v. 21 n. 77 (2020): Outubro; 209-2191678-6343reponame:Caminhos de Geografiainstname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/caminhosdegeografia/article/view/52794/30058Copyright (c) 2020 Bruno Del Rio Calvo, Tereza Cristina Souza de Oliveira info:eu-repo/semantics/openAccessDel Rio Calvo, Bruno Cristina Souza de Oliveira , Tereza2020-10-06T14:08:04Zoai:ojs.www.seer.ufu.br:article/52794Revistahttps://seer.ufu.br/index.php/caminhosdegeografia/indexPUBhttp://www.seer.ufu.br/index.php/caminhosdegeografia/oaiflaviasantosgeo@gmail.com1678-63431678-6343opendoar:2020-10-06T14:08:04Caminhos de Geografia - Universidade Federal de Uberlândia (UFU)false |
