Abstract:
The study presents experimental data on phytostabilization/ phytoremediation of 5.57% total petroleum hydrocarbons contaminated soils, using plants of the Achillea millefolium species. Studies have been conducted on pots placed in outdoors in three experimental variants in the absence/presence of an additional treatment: 1.contaminated soil; 2. contaminated soil treated with fertilizer agent, stabilized sewage sludge; 3. contaminated soil treated with fertilizer and amendment based on indigenous volcanic tuff with clinoptilolite. After five months of growth the plant roots have formed a strong twinned network throughout the vegetation soils of volume pots. The content reduction of the total petroleum products in the contaminated soil was 45.4% and 65.4% for the variant of contaminated soil treated with fertilizer agents, anaerobically stabilized sewage sludge from the municipal treatment plant in the absence/presence of the amendment with indigenous volcanic tuff.
