The article is devoted to the study of methods for cleaning soils contaminated with petroleum products in the process of eco-tourism in order to preserve the natural environment. Bakoil-KZ biological product, created on the basis of hydrocarbon-oxidizing microorganisms, was used for soil purification. The use of this drug increased the degree of soil purification from petroleum products from 67.8% to 97.2%, with the most effective dosage being 2 g/kg. Morphological analysis and biotesting using watercress sprouts showed the absence of toxic properties in the purified soil. In experiments with the addition of Bakoil-KZ (1 g/kg and 5 g/kg), 84–82% and 88–90% of seeds germinated, respectively, which indicates soil purification. In polluted soil, only 19–23 seed specimens (38–46%) germinated without the addition of biological products, which indicates a slow self-purification process. The use of Bakoil-KZ is environmentally safe, prevents environmental disasters, requires fewer resources and allows land plots of various scales to be cleaned without damage to the ecosystem. This makes the drug an effective tool for soil restoration in touristically active areas. Effective management of soil pollution elimination and the use of modern cleaning methods, such as Bakoil-KZ biologics, play a key role in preserving the pristine nature of unique natural areas. The introduction of sustainable tourism practices and technologies will help minimize the negative impact on the environment and contribute to the conservation of biodiversity and ecosystems.
