    Opis:
    Contamination of soil and water with petroleum during its extraction, collection, transportation, storage and preparation occurs frequently, and purification of oil spills is one of the pressing environmental problems of oil producing organizations. There are a large number of methods for utilization oil spills. The sorption method in combination with bioremediation is capable of effectively purification of petroleum contaminated soils. The paper shows the possibility of using a carbonized mixture of shungite from the Koksu deposit (Kazakhstan) with rice husk as a sorbent and carrier of microorganism strains. The physicochemical properties and elemental composition, as well as the microstructure of carbonized samples were established. The maximum sorption capacity of carbonized sorbents when purifying the soil samples from oil from the Karazhanbas field was 1.86 g/g after 60 days. The carbonized samples with microorganism strains immobilized on them showed a degree of oil destruction reaching 90%.

    Opis:
    A laboratory experiment lasting for 90 days was conducted to examine the interaction between a remediation plant, Gossypium hirsutum, and the petroleum contaminated soil. Root indices and 9 various types of soil enzymatic activities in two separate groups were determined. Results showed that compared to the uncontaminated control, the growth of cotton roots was slightly strengthened at the pollution level of 1000 mg-kg-1, while seriously inhibited at the pollution level of 2000 mg-kg-1 and 4000 mg-kg-1. At the same pollution level, all studied soil enzymatic activities except alkaline phosphatase were markedly higher in the group with plants than in the group without plants which may indicate that the content of nutrients essential for plant growth as well as the activities of microorganisms capable of degrading contaminants were both enhanced in soils planted with cotton, therefore conducive to the increase of the overall fertility level and the degradation of pollutants in the petroleum contaminated soil.

    Opis:
    In recent years, an increase in environmental pollution has been observed due to rapid industrialization, unsafe agricultural practices, and increased human activities on energy reservoirs. The wide use of petroleum hydrocarbon products as energy sources has contaminated the soil and the environment, thereby posing serious threats to all life forms, including humans. This study aimed to investigate the role of poultry droppings and pig dung in enhancing the bioremediation of diesel-contaminated soil. Soil samples were collected, processed by air drying and sieving, weighed in experimental bowls (5000 g), and contaminated with 250 ml of diesel. Then, poultry droppings and pig dung were added to the soil samples in different ratios, namely 1 : 1, 1 : 2, and 2 : 1. The diesel contaminated soil sample without treatment served as the control. Thirty days after exposure to the experimental treatment regimes, the total bacterial count and the hydrocarbon-utilizing bacterial count of the diesel contaminated soil ranged from 0.4 × 104 to 2.7 × 104 CFU/g and from 0.1 × 104 to 2.1 × 104 CFU/g, respectively. The total fungal count and the hydrocarbon-utilizing fungi count ranged from 0.6 × 103 to 2.1 × 103 SFU/g and from 0.2 × 103 to 1.7 × 103 SFU/g, respectively. Bacillus subtilis, Micrococcus sp., Pseudomonas aeruginosa, Proteus vulgaris, Aspergillus niger, Penicillium sp., and Mucor sp were found to be active degraders. A significant reduction in the total aliphatic hydrocarbon (TAH) content of the diesel-contaminated soil was reported, with remediation approaching 95% in 30 days when the poultry droppings – pig dung mixture was added to the soil. The remediation of diesel-contaminated soils is important for the enhancement of the ecosystem. This study has shown that the use of farm waste such as the poultry droppings – pig dung mixture can enhance the remediation of diesel-contaminated soils.

    Opis:
    Do najczęściej stosowanych metod oczyszczania gleb skażonych substancjami ropopochodnymi należą technologie oparte na metodach biologicznych z wykorzystaniem specjalistycznych szczepów mikroorganizmów. Główną rolę w tych procesach odgrywają mikroorganizmy wykorzystujące węglowodory jako źródło węgla. Pryzmowanie jest jedną z metod bioremediacji zanieczyszczonej gleby, należącą do metod ex situ, związaną z wywiezieniem skażonej gleby do miejsca jej oczyszczania. Celem publikacji jest przedstawienie i scharakteryzowanie metody pryzmowania skażonej związkami ropopochodnymi gleby oraz ocena skuteczności tej metody, przeprowadzona na podstawie analizy wyników badań pod kątem zawartości substancji ropopochodnych, na przykładzie konkretnego zdarzenia.
    The most commonly methods used for cleaning up soils contaminated with petroleum substances are the technologies based on biological methods using special strains of microorganisms. The main role in these processes play microorganisms using the carbohydrate as a carbon source. Prism is one of the methods of bioremediation of contaminated soil, belonging to the ex situ methods, involving the transport of contaminated soil to the place of purification. The aim of the article is to present and characterize the method of prism of the soil contaminated with the petroleum compounds and to evaluate the effectiveness of this method, carried out on the basis of the test results regarding the content of petroleum substances, for example, considering the particular incident.

    Opis:
    The developing oil and gas industry in the modern world, including the territory of the Russian Federation, does not remain without a trace for the environment. Land is the national wealth of each state, so it is very important to preserve its natural potential and prevent environmental disasters. Accidents at the territories of operating oil pipelines, which cause great harm to all kinds of natural resources – and first of all to land resources – remain unavoidable. The presented research reveals the methodology of the detailed assessment of the level and degree of soil contamination by oil products. The assessment scale was developed and five zones with different degrees of soil contamination by oil products were established. Using the calculation and a graphic method, a map of zones with the degree of contamination was developed and their exact areas were established. The presented development will be used when carrying out land reclamation of the territory under study.
