REMEDIATION OF SOILS CONTAMINATED SPENT OILS USING EARTHWORMS DENDROBENA VENETA AND MICROBIOLOGICAL PREPARATION "BAIKAL-EM"
Evaluated survival of earthworms in soil contaminated with spent lubricating oil in the amount of 20–100 g/kg for four months and studied the effectiveness of bioremediation massagrande the soil using earthworms Dendrobena veneta in the presence of microbial drug Baikal EM. Found that the content of the waste oil in soils with earthworms decreased 4–10 times faster compared to contaminated soil without worms. High rates of decomposition of waste oil observed in the presence of earthworms D. veneta. Moreover, the oil content in the soil in this case was reduced by 60-90 %. When the content of oil in soil in amounts of 60–100 g/kg, and injected into the soil Dendrobena veneta, the oil concentration decreased from 12 to 23 times.
