Resumo: | Acute toxicity evaluation of cutting fluids used in manufacturing processes to Poecilia reticulata and Daphnia magna. Grinding operations are very significant among the manufacturing processes of the metal-mechanic industry. In conventional grinding, cutting fluids are of great concern for improving productivity, but also for being hazardous to the environment. In order to contribute to the knowledge of the actual toxic effects of these products in aquatic environments, the present work assesses the toxicity potential through acute toxicity tests of three different kinds of cutting fluids, with three different usage times. The tests were carried out using the fish Poecilia reticulate and the microcrustacean Daphnia magna as test organisms. These tests made it possible to determine the Median Lethal Concentration (LC50) for the fish and the Median Effective Concentration (EC50) for the microcrustacean. The results indicate that, after storage, the toxicity potential of cutting fluids decreases. However, in the three situations investigated, the product presented a high toxicity potential, which reinforces the need of special care in its handling, usage and disposal. |

No sentido de contribuir para o conhecimento dos reais efeitos tóxicos destes produtos em ambientes aquáticos, o presente trabalho faz uma avaliação do potencial tóxico, através de testes de toxicidade aguda, de três diferentes tipos de fluidos de corte comercialmente utilizados, com três diferentes tempos de uso. Os testes foram realizados utilizando como organismo -teste o peixe Poecilia reticulata e o microcrustáceo Daphnia magna. Estes testes possibilitaram determinar a Concentração Letal Mediana (CL50) para o peixe e a Concentração Efetiva Mediana (CE50) para o micro- crustáceo. Os resultados obtidos indicam que após armazenagem o potencial tóxico dos fluidos de corte reduz. Contudo, o produto, nas três situações avaliadas, possui potencial tóxico elevado o que reforça a necessidade de cuidados especiais no seu manuseio, utilização e descarte.Universidade Federal de Santa Catarina2006-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/21120Biotemas; v. 19 n. 3 (2006); 7-132175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/21120/19075Copyright (c) 2006 Alexandre Magno de Paula Dias, Débora Monteiro Brentano, Cátia Regina Silva de Carvalho-Pinto, William Gerson Matiashttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessde Paula Dias, Alexandre MagnoBrentano, Débora MonteiroCarvalho-Pinto, Cátia Regina Silva deMatias, William Gerson2022-11-21T11:44:09Zoai:periodicos.ufsc.br:article/21120Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2022-11-21T11:44:09Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |

Acute toxicity evaluation of cutting fluids used in manufacturing processes to Poecilia reticulata and Daphnia magna. Grinding operations are very significant among the manufacturing processes of the metal-mechanic industry. In conventional grinding, cutting fluids are of great concern for improving productivity, but also for being hazardous to the environment. In order to contribute to the knowledge of the actual toxic effects of these products in aquatic environments, the present work assesses the toxicity potential through acute toxicity tests of three different kinds of cutting fluids, with three different usage times. The tests were carried out using the fish Poecilia reticulate and the microcrustacean Daphnia magna as test organisms. These tests made it possible to determine the Median Lethal Concentration (LC50) for the fish and the Median Effective Concentration (EC50) for the microcrustacean. The results indicate that, after storage, the toxicity potential of cutting fluids decreases. However, in the three situations investigated, the product presented a high toxicity potential, which reinforces the need of special care in its handling, usage and disposal. |
