Resumo: | Studying aquatic bodies is fundamental to understanding socio-environmental relationships, as anthropic actions and the natural environment establish a mutual relationship of influence. Amidst the diverse water resources, urban lakes are noteworthy, as they are constantly being modified as a result of population growth. And among the various elements that make up an aquatic body, sediments are important for evaluating the quality of these environments, as they have a high capacity to adsorb contaminants. In this sense, this study aimed to evaluate the concentration and behavior of metals (Fe, Ni, Cd, Zn, Cr, Cu, Mn, Pb) in sediments over time in the main lagoons of Feira de Santana, and thus provide data that explain the superficial contributions. To achieve the purpose of this work, five sediment cores were collected, 3 in Lagoa Salgada and 2 in Lagoa Suba?. The geochemical results obtained in the aquatic bodies showed that they present evidence of contamination by lead in the two lakes and by chromium in the suba? lake. The sediments present granulometric fractions that vary from the siltic sand category to sandy silt. The correlation was significant only between Fe and Mn, as well as Ni and the particle size fractions. While the cluster analysis showed that testimonies 1 - 2 and 3 - 4 had similarities, being 5 different from the others. The IGEO result did not represent contamination in both environments. Therefore, the analyzes allowed us to conclude that the analyzed results do not represent the degree of contamination in the lakes, therefore, a careful look is suggested to avoid future problems in these environments. |

Em meio aos diversos recursos h?dricos, as lagoas urbanas merecem destaque, por estarem sendo modificadas constantemente, em decorr?ncia do crescimento populacional. E dentre os diversos elementos que comp?e um corpo aqu?tico, os sedimentos s?o importantes para avalia??o da qualidade desses ambientes, uma vez que possuem alta capacidade de adsorver contaminantes. Nesse sentido, esse estudo teve como objetivo avaliar a concentra??o e o comportamento dos metais (Fe, Ni, Cd, Zn, Cr, Cu, Mn, Pb), em sedimentos, ao longo do tempo, nas principais lagoas de Feira de Santana, e assim oferecer dados que expliquem as contribui??es superficiais. Para alcan?ar a proposta desse trabalho, foram coletados cinco testemunhos de sedimentos, sendo 3 na Lagoa Salgada e 2 na Lagoa Suba?. Os resultados geoqu?micos obtidos nos corpos aqu?ticos demonstraram que eles apresentam ind?cios de contamina??o por chumbo nas duas lagoas e por cromo na lagoa suba?. Os sedimentos apresentam fra??es granulom?tricas que variam da categoria areia s?ltica a silte arenosa. A correla??o foi significativa apenas entre Fe e Mn, bem como, Ni e as fra??es granulom?tricas. Enquanto que a an?lise de cluster demonstrou que os testemunhos 1 - 2 e os 3 - 4 apresentavam semelhan?as, sendo o 5 diferente dos demais. O resultado do IGEO n?o representou contamina??o nos dois ambientes. As an?lises permitiram concluir portanto, que os resultados analisados n?o representam grau de contamina??o nas lagoas, sendo sugerido portanto, um olhar cuidadoso para evitar futuros problemas nesses ambientes.Submitted by Amanda Ponce (aponce@uefs.br) on 2023-07-04T15:22:12Z No. of bitstreams: 1 Layanne_Dissertacao_ppgm.pdf: 4825865 bytes, checksum: 7466c8b9e1e32605aa31997dfaec3168 (MD5)Made available in DSpace on 2023-07-04T15:22:12Z (GMT).
