Humic Compounds in Treatment of Oil Contaminated Environments

The study considers main areas of use of humic substances — main matrix of organic matter in soil and water — in environment protection technologies. Humic compounds are proved to be the most widely used in bio- and phytoremediation of oil contaminated soils as the boosters of microorganism vitality and plant growth, as well as the improvers (ameliorants) of crude oil- and oil product contaminated soils promoting biodegradation of petroleum hydrocarbons. But the variety of raw material sources and humate production methods leading to high variability of properties, and absence of scientific approaches to their use result in contradictory appraisals of their performance. The conclusion is made to necessitate systematic research on processes of decontamination of petroleum hydrocarbons by humic substances and to develop for the selection criteria of humic substances to be used in cleaning technologies.
