Abstract:
The potential toxicity in riverbed sediments was assessed with a bioassay by means of the bioluminescent bacteria Vibrio fischeri. The elected area was characterized by the attendance of ultramafic rocks (peridotites), and the sediments had elevated values in Ni, Cr, and Co. For the toxicity bioassay with Vibrio fischeri, water-soluble forms were worn. The results indicated that mainly of the samples had a very low quantity of toxicity, with 14% of decrease in luminescence in relative to the organize; meanwhile 29% of the samples had a reasonable degree of toxicity with a decrease in luminescence among 15 and 23% in relation to the manage. The toxicity index interrelated considerably with the concentrations of Ni and Cr in the water extracts. This toxicity bioassay was proved to be a responsive and functional tool to detect potential toxicity in solutions, even with inconsistent concentrations in heavy metals of ordinary origin. . Ecological risk assessments can be worn to anticipate the likelihood of future belongings or approximation the likelihood that effects are caused by past opening to stressors.
