The article presents the diagnosis of contamination of light chestnut soils of Volzhsky, Volgograd region with petroleum products and heavy metals using various bioindicators: earthworms of the genus Lumbricus rubbellus and fungus of the genus Botryitis cinerea. The following indicators of bioindication of soil pollution were identified: the survival rate of the earthworms Lumbricus rubbellus, the total microbial number of light chestnut and the mycelium mass of the fungus of the genus Botrytis cinerea. In clay and sandy light chestnut soils that are contaminated with oil and petroleum products, the mortality of earthworms of the genus Lumbricus rubellus was noted on day 7. After 7 days, the spores of the Botrytis cinerea fungus began to grow on the control and light chestnut sandy soil of gas station number 3, and after 14 days -- on other soils. The survival rate of earthworms depends on the quality of petroleum products and does not depend on the granulometric composition of soils. The largest total microbial number of light chestnut soil, estimated by the Botrytis cinerea fungus, is observed in the sandy soil of gas station number 3 (133333 CFU/cm³ of water soil extract), and the smallest -- in the clay soil of gas station number 1 (6773 CFU/cm3 of water soil extract).
