Approaches to determination of toxicity of oil containing waste by using of biological indication and biological testing

Analysis of using of methods of biological indication and of biological testing for determination of degree of toxicity of oil-containing waste has been carried out, which have showed efficiency of using of these methods. The scale of estimation of degree of toxic impact of oil containing waste to biosphere according to the summary rating score has been suggested. Using methods of biological testing, analysis of probes of soil taken near to the petrol stations, oil pipelines and in the other places of potential oil spill have been carried out. In all cases acute toxicity of the studied samples has been determined. Results of work are allowing us to carry out more efficient and high quality reduction of negative impact of oil containing waste to biosphere and to reduce the degree of its toxic impact.
