The aim of this study was to examine the water quality Extrema River spring in a Brazilian Cerrado area. Three collection sites (P1 - P3) were sampled dry and rainy seasons, which are close industries from different sectors. In physicochemical analysis, decrease dissolved oxygen levels (<5 mg/L) pH (< 6) at P3 detected. An increase heterotrophic bacteria count recorded all (> 500 colonies/ml). ecotoxicological analyses, P2 exhibited toxicity using Vibrio fischeri 20%). evaluating toxicity, reduction seed germination significant utilizing Lactuca sativa locations with Allium cepa only P2; rootlet length decreased on L. A. cepa. contrast, loss membrane integrity mitochondrial function meristems adversely affected both assays. Principal components analysis (PCA) approach indicated that seasonality apparently did not markedly interfere obtained data, but it is important include more be evaluated multiple bioindicators region. Our data indicate urgent need for rigorous programs monitor discharge effluents into springs.
