Abstract
Nitrifying bacteria were tested to determine their applicability as a Level I bioassay organism. Level 1 testing involves general bioassay and analysis procedures that will identify the presence of toxicity in a given waste stream. The toxicity of five metals and three organic toxicants to the nitrifying bacteria (Nitrobacter and Nitrosomonas) were determined and compared to other common bioassay organisms. In general, bacterial exhibited somewhat lower sensitivity for general metabolic toxicants, but dramatically lower sensitivity for specific target-site toxicants. The application of the bacterial bioassay was shown for two cases of Level I testing: a field study of a toxic industrial waste and its pre-treatment and an assessment study of the potential leachate problems for a flue-gas scrubber solid waste.
