Abstract
Under the laboratory conditions, we studied water migration and degradation of shaimskoy oil in the soil of bogs of the Khanty-Mansi Autonomous District, as well as the toxicity of successive portions of water extracts, using test objects Ceriodaphnia affinis, Paramecium caudatum, Allium cepa. It is established that oil (up to 2 g/kg) is retained by the humic matrix of peat and does not pass into water. At the same time, the bioassay method allows to fix the toxic effect of the leachate of oil-contaminated peat even in cases when petroleum products are not detected by means of IR photometry.
