Phytoremediation of areas polluted with oil products using organic fertilizers type of sewage sludge

They studied variants of phytoremediation of contaminated soils plants with different amounts of crude oil (total petroleum hydrocarbon (TPH): 1. ground with low pollution 1g / kg D.M.cultivatted in the following
versions: leguminous plants Vicia spp. or Onobrichis spp., grasses Lolium spp and grasses Lolium spp.;
2. average soil pollution with 27,6-28,6g / kg DM cultivated with: legumes Vicia spp. plants or Onobrichis and grasses Lolium spp.; 3. soil pollution with 18.46 ± 2 30g / kg D.M. cultivation with Glycine max, 4. soil pollution than 64.3 ± 3.5 g / kg D.M mice with wild plant (Hordeum murinum) 5. sol with high pollution 55.45 ± 0.25 g / kg D.M.cultivated with plants of mouse tail 6. Very high polluited soil with 113,5g and 80.5 g / kg D.M by culture of small trefoil (Lotus corniculatus). TPH variants were realized on phytoremediation of polluted soils fertilized with sewage sludge in the absence / presence of additives acting as adsorbent / amendment as indigenous volcanic tuff, ash from coal combustion in power plants fossil plants. For experimental
variations of phytoremediation were developed models. Were developed two technologies for phytoremediation of soils contaminated with TPH
