The aim of this case study was the evaluation of the selected metals’ concentration, potential toxic compound identification, cytotoxicity analysis, estimation of the airborne dust concentration, biodiversity, and number of microorganisms in the environment (leachate, soil, air) of the biggest uncontrolled post-industrial landfills in Poland. Based on the results obtained, preliminary solutions for the future management of post-industrial objects that have become an uncontrolled landfill were indicated. In the air, the PM1 fraction dominated, constituting 78.1–98.2% of the particulate matter. Bacterial counts were in the ranges of 9.33 × 101–3.21 × 103 CFU m−3 (air), 1.87 × 105–2.30 × 106 CFU mL−1 (leachates), and 8.33 × 104–2.69 × 106 CFU g−1 (soil). In the air, the predominant bacteria were Cellulosimicrobium and Stenotrophomonas. The predominant fungi were Mycosphaerella, Cladosporium, and Chalastospora. The main bacteria in the leachates and soils were Acinetobacter, Mortierella, Proteiniclasticum, Caloramator, and Shewanella. The main fungi in the leachates and soils were Lindtneria. Elevated concentrations of Pb, Zn, and Hg were detected. The soil showed the most pronounced cytotoxic potential, with rates of 36.55%, 63.08%, and 100% for the A-549, Caco-2, and A-549 cell lines. Nine compounds were identified which may be responsible for this cytotoxic effect, including 2,4,8-trimethylquinoline, benzo(f)quinoline, and 1-(m-tolyl)isoquinoline. The microbiome included bacteria and fungi potentially metabolizing toxic compounds and pathogenic species.

“…At the same time, the structure of the microbial community changes in oil-contaminated soil [4][5][6][7], the photosynthetic activity of higher plants is suppressed [8][9][10][11], and the microrelief changes, i.e., its general condition changes significantly. Thus, the consequences of oil impact are profound changes in the physical and agrochemical properties of the soil, as well as toxic stress to which soil biota is exposed [12][13][14]. The processes of self-purification of soils contaminated with petroleum products proceed slowly, the toxicity of the soils is high and they almost completely lose their biological characteristics.…”

The article presents the results of research of the hydrocarbon composition of petroleum extracted from contaminated soils of oil fields in the Aral Sea region. The work has been carried out to assess the level of contamination with petroleum hydrocarbons and determine various approaches to their remediation, taking into account the nature of their use. The gravimetric method has been used to determine the oil content in contaminated soil, which is 66866.60 mg/kg and 26296.66 mg/kg for the soil of the Kumkol and Taur oil fields, respectively.Using a gas chromatography-mass spectrometer “Agilent” - 7890A/5975C, the petroleum hydrocarbon compositionin soil samples has been studied. Based on the research findings, it has been determined that oil extracted from contaminated soil of the Kumkol field contains 80.10% alkanes, 6.10% naphthenes and 5.90% arenes. Oil extracted from contaminated soil of the Taur field contains 85.39% alkanes, 6.70% naphthenes and 0.59% arenes. Also, the studied oil samples contain oxygen-, sulfur-, and halogen-containing hydrocarbon derivatives in the ratio of 7.90 and 7.32, respectively.The results of gravimetric and chromatographic analysis ofpetroleumextracted from contaminated soil show that the level of soil contamination with residual petroleum products creates a dangerous level of benz(a)pyrene formation and the substrate acquires toxicity properties. Very negative conditions for the development of zonal plants, a nonequilibrium maximum optimum for oil-oxidizing microorganismsare formed. The water and air regime of soils changes and full-scale remediationactions and activation of the microbial communityare required. It is necessary to control the migration of petroleum hydrocarbons, especially benz(a)pyrene. From the point of view of environmental protection, a certain approach to their remediation is required, taking into account the nature of use.

Contamination of soils by automotive residual oil represents a global environmental problem. Bioremediation is the technology most suitable to remove this contaminant from the medium. Therefore, this work aimed to evaluate the effectiveness of bioremediation of automotive residual oil-contaminated soils by biostimulation with enzymes, surfactant, and vermicompost. The bioremediation efficiency was examined using a factorial design of 24 to determine the effect of the time, pH and temperature conditions, biostimulation with enzyme-vermicompost, and biostimulation with enzyme-surfactant. Enzymes obtained from Ricinus communis L. seeds, commercial vermicompost, and Triton X-100 were used. Results showed that the highest removal efficiency (99.9%) was achieved at 49 days, with a pH of 4.5, temperature of 37 °C, and using biostimulation with enzyme-vermicompost (3% w/v–5% w/w). The addition of surfactant was not significant in increasing the removal efficiency. Therefore, the results provide adequate conditions to bioremediate automotive residual oil-contaminated soils by biostimulation using enzymes supported with vermicompost.
