    Opis:
    Biodegradation can be a possible and effective retort to soil contamination by petroleum hydrocarbons. Nowadays there are many cases of accidental releases of petroleum products into the environment. Use of biological agents especially microorganism is effective in degradation of complex organic contaminants to other simpler organic compounds. In our present study role of Myroide odoratimimus in degrading the diesel components present in soil to simpler units were checked. The study demonstrates that Myroides odoratimimus (SKS 05) showed the ability to degrade diesel after 40 days of incubation in the diesel adsorbed soil with a growth rate of 6.2×106 CFU/ml and from the GC study Myroides odoratimimus degraded the component Dotriacontane (25.471), Hexatriacontane (27.98), Tetracosane (30.296), Pentatriacontane (32.42), Tetrapentacontane (34.39) present in the diesel adsorbed soil, which was confirmed by the reduction in the peak height and the peak area in comparison to the control {without Myroides odoratimimus (SKS 05).

    Opis:
    The aim of the study was to assess the impact of diesel oil on the activity of oxidoreductases in loamy sand, and to evaluate effect of selenium addition in the restoration of homeostasis of soil contaminated with diesel oil. The experiment was carried out under laboratory conditions with loamy sand. 0.05 mmol/kg of selenium (Se(IV) or Se(VI)), and diesel oil in the doses of 2, 10 and 50 g/kg were added to the soil samples. In soil treated with selenium and diesel oil activities of dehydrogenases, catalase, o-diphenol oxidase and nitrate reductase were measured on 1, 7, 14, 28, 56 and 112 day of the experiment. Contamination with diesel oil did not cause significant changes only in the activity of o-diphenol oxidase. The highest increase was observed in activity of dehydrogenases. Selenium limited hydrocarbons impact on activity of soil oxidoreductases, especially in loamy sand with diesel oil in the dose of 10 g/kg. Obtained results showed that this effect was reduced after treatment with selenium in both oxidation states but for nitrate reductase and catalase this reduction was reported after application of Se(VI) and Se(IV), respectively.

    Opis:
    The drilling of any oil and gas well is accompanied by the use of drilling fluids consisting of chemical reagents and materials of varying degrees of environmental hazard. The existing drilling waste disposal technologies are expensive, energyand labor-intensive, and do not always contribute to the formation of environmentally friendly compounds. In this regard, the possibility of using destructor microorganisms capable of growing and exhibiting biochemical activity under the conditions of complex pollution, in an environment with a high content of hydrocarbons, surfactants and polymer additives capable of biodegrading these substances, is relevant. In connection with the foregoing, the search for new strains of bacteria for the disposal of drilling waste, which are resistant to the conditions of complex toxic effects of drill cuttings components and, at the same time, capable of providing a significant degree of detoxification of the reagents that are part of hydrocarbon-based solutions, is relevant.

    Opis:
    Diesel fuels currently constitute around 60–70% of the turnover of fuel bases in Poland. Diesel fuels are stored in vertical steel tanks with fixed roofs, which, according to applicable legal acts, do not require airtight sealing. This results in the emission of gases containing hydrocarbons to the atmosphere, which at high turnover of fuel bases generates the need to determine the concentration of hydrocarbons emitted to the atmosphere and to perform calculations of concentrations occurring at the boundary of the fuel base site. The article collects available literature data and presents the results of research on the emissions of hydrocarbons to the atmosphere that occur during handling and storage of diesel fuel in storage tanks, including the determination of the saturated vapor pressure of the hydrocarbon components of the tested diesel fuel depending on the temperature. The emissions tests were carried out by taking gas samples emitted during operations on diesel storage tanks. Analyzes of the gas samples supplied in gas-tight syringes were performed with SRI 8610C gas chromatograph equipped with a flame ionization detector (FID) and an alumina packed column. Diesel oil sample analysis was performed by gas chromatography using Shimadzu GC-2010 Plus chromatograph equipped with flame ionization detector (FID). ZB-5HT column (30 m × 0.25 mm × 0.25 µm) was used for the separation of the substances. Research has shown the amount of hydrocarbon emissions to the atmosphere depending on the type of loading operations, the degree of storage tank filling and oil temperature. The dependence of the concentration of hydrocarbons emitted from the storage tank depending on the degree of filling of the tank has been determined in the research. Results of calculations of diesel vapor pressure show convergence with most available literature data and measurement results. General design guidelines have been defined to determine the data necessary to calculate the level of hydrocarbon concentrations in atmospheric air. The research was aimed at creating the basis for the required environmental calculations, relevant in the absence of relevant literature data, necessary for the reliable determination of the amount of hydrocarbon emissions.
