The purpose of the work is environmental assessment and restoration of oil-contaminated soils using higher plants.

Linum usitatissimumL., Helianthus annuus L. and Fagopyrum vulgare St. are sensitive to oil pollution and are suitable for biotesting of the oil-contaminated soils at early stages of germination in the wide range of concentrations of oil in soil (0–20%). High sensitivity of F. vulgare to low concentrations of oil in the soil near approximately admissible level (0.4% of oil in the soil) was discovered and proved for the first time. F. vulgareis recommended to use for bioindication of oil-contaminated soils.

A scale of toxicity of oil-contaminated soils is suggested, which shows the relationship between phytotoxicity, content of oil in soil and pollution level. The method of environmental assessment of oil-contaminated soils was tested on the oil-contaminated soils – dumps of Borislav Ozokerite Mine and its efficiency is proved. Optimum conditions for carrying out a phytoremediation are determined.

The expediency of using Hippophae rhamnoides for phytoremediation of oil-contaminated soils was proved.  Hippophae rhamnoides plants successfully adapt to adverse conditions of the oil-contaminated soils and improve physical, chemical and biological properties of soils, reduce oil content in the soil. The degree of soil cleaning from oil pollution reaches 92.7%. An ecological-economic evaluation of phytoremediation of oil-contaminated soils using Hippophae rhamnoides was carried out.
