| Abstract: | A model experiment was performed to study the effect of soil contamination with oil on the growth of wheat plants. Neither significant downward migration of oil or oil components, including the most mobile aromatic hydrocarbons, in a column with leached chernozem nor removal of these compounds from the column were observed when the initial oil concentration was below 0.75%. These data confirmed the previous results that oil at a concentration of 0.3% had no negative effect on the growth of wheat. The synergetic effect of oil, soluble salts, and exchangeable sodium should be taken into account in the determination of maximum permissible residual oil content in soils. |
