Resumo: | The toxicity of environmental contaminants such as polycyclic aromatic hydrocarbons (PAHs), heavy metals and cyanotoxins has frequently been investigated for its biochemical, cellular and pathological aspects on animals and humans. Among heavy metals, copper is a chemical element that in trace concentrations is commonly found in natural and artificial lakes. The increase in the concentration of this metal in fishing ponds due to the use of algicides, such as CuSO4, or by leaching of the soil, is responsible for the intoxication of aquatic organisms, particularly fish, therefore representing a potential risk to human health. The aim of this study was to determine the phytoplanktonic composition, physicochemical characteristics and the main organic and inorganic contaminants of the water bodies, as well as to evaluate the acute toxicity of the crude effluent from the Jaó fishing pond using histological, ethological, genotoxic and enzymatic endpoints in Poecilia reticulata. Concentrations of Cu2+, phosphorus and nitrogen were higher than allowed by CONAMA resolutions 357 and 430, which, in synergy with other chemical contaminants in the mixture, caused acute toxicity to P. reticulata exposed during the dry season (EC50-96h of 60.48% for males and 85.08% for females) and for rainy (EC50-96h of 32.29% for males and of 49.50% for females). This study demonstrated that copper has a pronounced deposition on the hepatic parenchyma of males and females of P. reticulata. In the analysis of the medial portion of the small intestine, it was observed that the increase in mucin production is a physiological response to stress induced by copper, quantified in the fishing effluent, so that the same results were observed when the specimens were exposed to the average lethal concentration of 96 hours (CL50-96h) to Cu2+ (0.82 ± 0.17 mg.L-1 of CuSO4). It was also observed the genotoxic effect of the effluent from the dry and rainy season on the P. reticulata erythrocytes, so that the females had a higher sensitivity (p <0.05) to the copper contamination. In enzymatic assays, the activity of carboxylesterase (CarbE) was reduced (p <0.05) in females exposed to the rainy season effluent and no changes in the activity of catalase (CAT) and glutathione-S-transferase (GST) were observed. Mitigating measures should be taken to reduce contamination by copper and macronutrients in the fishing pond studied, thus avoiding potential risks to the aquatic and human communities. |

Dentre os metais pesados, o cobre é um elemento químico que em concentrações traço, é comumente encontrado em lagos naturais e artificiais. O aumento na concentração desse metal em pesqueiros, devido ao uso de algicidas, como o CuSO4, ou pela lixiviação do solo, é responsável pela intoxicação dos organismos aquáticos, particularmente os peixes, que por consequência representam um risco potencial para a saúde humana. Esse estudo teve por objetivo determinar a composição fitoplanctônica, as características físico-químicas e os principais contaminantes orgânicos e inorgânicos dos corpos hídricos, além de avaliar a toxicidade aguda do efluente bruto do pesqueiro Jaó utilizando endpoints histológicos, etológicos, genotóxicos e enzimáticos em Poecilia reticulata. Foram encontradas concentrações de Cu2+, fósforo e nitrogênio acima do permitido pelas resoluções nº 357 e 430 do CONAMA, elementos que, em sinergia com demais contaminantes químicos em mistura, causaram toxicidade aguda para P. reticulata expostos no período de seca (CE50-96h de 60,48% para machos e de 85,08% para fêmeas) e de chuva (CE50-96h de 32,29% para machos e de 49,50% para fêmeas). Este estudo demonstrou que o cobre possui acentuada deposição sobre o parênquima hepático de machos e fêmeas de P. reticulata. Em análise da porção medial do intestino delgado, foi observado que o aumento na produção de mucina é uma reposta fisiológica ao estresse causado pelo cobre, quantificado no efluente pesqueiro, de modo que esses mesmos resultados foram observados quando os espécimes foram expostos a concentração letal média de 96 horas (CL50-96h) do Cu2+ (0,82 ± 0,17 mg.L-1 de CuSO4). Também foi observado o efeito genotóxico do efluente do período de seca e de chuva sobre os eritrócitos de P. reticulata de modo que as fêmeas apresentaram maior sensibilidade (p<0,05) a contaminação pelo cobre. Em ensaio enzimático a atividade da carboxilesterase (CarbE) foi reduzida (p<0,05) em fêmeas expostas ao efluente do período chuvoso não sendo observadas alterações na atividade da catalase (CAT) e da glutationa-S-transferase (GST). Medidas mitigadoras devem ser tomadas para que se reduza a contaminação por cobre e macronutrientes no pesqueiro estudado, evitando assim os riscos potenciais à comunidade aquática e pesqueira.Submitted by Luciana Ferreira (lucgeral@gmail.com) on 2019-06-24T14:49:38Z No. of bitstreams: 2 Dissertação - Rafael Cosme Machado - 2016.pdf: 4122092 bytes, checksum: 2af7574f8563c1d7b376340f9f4d5a01 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Approved for entry into archive by Luciana Ferreira (lucgeral@gmail.com) on 2019-06-25T13:09:28Z (GMT) No. of bitstreams: 2 Dissertação - Rafael Cosme Machado - 2016.pdf: 4122092 bytes, checksum: 2af7574f8563c1d7b376340f9f4d5a01 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Made available in DSpace on 2019-06-25T13:09:28Z (GMT).

description |
The toxicity of environmental contaminants such as polycyclic aromatic hydrocarbons (PAHs), heavy metals and cyanotoxins has frequently been investigated for its biochemical, cellular and pathological aspects on animals and humans. Among heavy metals, copper is a chemical element that in trace concentrations is commonly found in natural and artificial lakes. The increase in the concentration of this metal in fishing ponds due to the use of algicides, such as CuSO4, or by leaching of the soil, is responsible for the intoxication of aquatic organisms, particularly fish, therefore representing a potential risk to human health. The aim of this study was to determine the phytoplanktonic composition, physicochemical characteristics and the main organic and inorganic contaminants of the water bodies, as well as to evaluate the acute toxicity of the crude effluent from the Jaó fishing pond using histological, ethological, genotoxic and enzymatic endpoints in Poecilia reticulata. Concentrations of Cu2+, phosphorus and nitrogen were higher than allowed by CONAMA resolutions 357 and 430, which, in synergy with other chemical contaminants in the mixture, caused acute toxicity to P. reticulata exposed during the dry season (EC50-96h of 60.48% for males and 85.08% for females) and for rainy (EC50-96h of 32.29% for males and of 49.50% for females). This study demonstrated that copper has a pronounced deposition on the hepatic parenchyma of males and females of P. reticulata. In the analysis of the medial portion of the small intestine, it was observed that the increase in mucin production is a physiological response to stress induced by copper, quantified in the fishing effluent, so that the same results were observed when the specimens were exposed to the average lethal concentration of 96 hours (CL50-96h) to Cu2+ (0.82 ± 0.17 mg.L-1 of CuSO4). It was also observed the genotoxic effect of the effluent from the dry and rainy season on the P. reticulata erythrocytes, so that the females had a higher sensitivity (p <0.05) to the copper contamination. In enzymatic assays, the activity of carboxylesterase (CarbE) was reduced (p <0.05) in females exposed to the rainy season effluent and no changes in the activity of catalase (CAT) and glutathione-S-transferase (GST) were observed. Mitigating measures should be taken to reduce contamination by copper and macronutrients in the fishing pond studied, thus avoiding potential risks to the aquatic and human communities. |
