Resumo: This study aimed to test methodological aspects related to the kinetic use of oxygen consumption as an index of mineralization process in aquatic ecosystems. The experiment comprised 10 bottles (5 liters) with water samples from Monjolinho reservoir (22º 00’S and 47º 54’W) enriched with glucose (20 mg.L-1). The solutions were previously oxygen saturated and during 33 days the dissolved oxygen concentration and the temperature were registered. The anaerobic processes were avoided by reaerations, when the dissolved oxygen concentrations were near to 2.0 mg.L-1. Concerning to the fitting of the grouping data, the total amount of oxygen used in the mineralization processes was 12.4 mg.L-1, with the daily rates of consumption (k1) and reaeration (k2) equals to 7.7 and 3.7%. The non-parametric analysis (Kruskal-Wallis) showed that the use of 1 bottle is sufficient to describe the temporal oxygen consumption evolution through the adopted experimental conditions. However, due to experimental variations, the use of 3 bottles was suggested

Foram utilizados 10 frascos (vol. ≈ 5L) contendo soluções de glicose (20mg.L-1), preparadas com amostras de água da represa do Monjolinho (22º 00’S e 47º 54’W). As soluções foram inicialmente aeradas e durante 33 dias foram determinadas as concentrações de OD e as temperaturas. Os processos anaeróbios foram evitados através de reaerações, quando as concentrações de OD aproximaram-se de 2,0mg.L-1. A concentração média de oxigênio gasta para realizar os processos de mineralização foi 12,4mg.L-1, com taxas diárias de consumo (k1) e reoxigenação (k2) iguais a 7,7% e 3,7%, respectivamente. Com base em análise não-paramétrica (teste de Kruskal-Wallis), foi possível verificar que, para a execução de experimentos de mineralização sob as condições adotadas, a utilização de 1 frasco foi suficiente para o acompanhamento da evolução do consumo de OD. No entanto, devido às variações observadas, a utilização de 3 frascos pode ser apontada como idealUniversidade Estadual De Maringá2008-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/197510.4025/actascibiolsci.v25i2.1975Acta Scientiarum.
