Abstract: This paper describes the testing and corresponding results of the preparation “Rhoder” in comparison with several other bioremediation variants during the field trials in Komi Republic throughout 2002–2003. All bioremediation trials were performed on one vast polar marshy wetland polluted by accidental crude oil spill and uncovered by grass. After application of the “Rhoder” at the site, with an area of ∼2000 m2, during the cold and rainy summer of 2002 (1.5 months), the level of oil contamination decreased by 20–51%, depending on initial oil pollution (458–738 g/kg dry weight of soil). In the middle of September 2002, the treated site was covered by 70–85% with green grass. Though, during 2003, the “Rhoder” treatment was not practiced, at the end of August 2003, the site was already covered by 85–95% with green grass and the level of oil contamination further decreased by 54–79% from the initial level of oil pollution at the beginning of 2002. These results were much better compared to those from other bioremediation variants applied at this spill. [Copyright &y& Elsevier] |
