The role of secondary pollution problem is growing in the contemporary world. This paper observes biotesting of the secondary oil pollution adsorbed by soil. It is a common problem during the recultivation of lands after oil spillages.
The authors describe the problem of oil pollution in the Tyumen Region, the most popular methods of soil remediation, soil sorption properties, and they provide examples of the negative impact f oil on organisms. The employed methodology includes preparation of the aqueous extract, the definition of the texture of the soil, as well as the methods of biotesting solutions on Paramecium caudatum. This paper describes the toxicity biotesting for both recent and secondary oil pollution , adsorbed by soil.
The authors have discovered the difference in secondary pollution of soil types: sand, peat, and clay — at different stages of oil pollution. The received data can aid remediation operations after oil pollution and for planning soil recovery.
