Opis:: This work is devoted to studying the dynamics of changes in phytotoxicity of oil-contaminated meadow soils in the process of microbial bioremediation. The research was conducted under laboratory and field conditions. Winter rye (Secále cereále) was selected as the test object. In order to assess the degree of toxicity in the laboratory, the indicators of seed germination – germination rate and germination energy-were determined. In a field experiment, the ecological state of oil-contaminated soils was evaluated by the germination rate and the amount of aboveground plant biomass. The research results showed that the content of petroleum products significantly affected the percentage of germination of rye seeds. There are differences in the size of seedlings for different experimental schemes: in all tests, the average height of cleoptila on polluted soil was less than on unpolluted soil, but at the same time it varied for different experimental bioremediation schemes. The use of potassium humate and modified vermiculite as additives significantly reduced the toxicity of the oil-contaminated soil.

Opis:: Given the complex links to the major economic activities and climate variability, water is becoming the most fiercely contested resource, challenging human survival and food security especially in arid hot dry regions, such as in the Middle East and North Africa areas (MENA). In the Kebili and Tozeur regions in southern Tunisia, groundwater resources undergo abusive exploitation mostly for agricultural activities. The lack of efficient management and adequate conservation strategies to ensure sustainable exploitation has resulted in gradual irreversible ecological and geological effects. Thus, this review paper provides a useful background synthesis for the critical assessment of the recursive dynamic substantial increase in freshwater in these regions, using a general equilibrium model of hydrodynamic and chemical changes of aquifers based on several water scarcity indices and economic-ecological factors. The collected data highlight the good correlation between the reviewed studies and the observed and (or) measured disturbance of the natural functioning of the deep confined aquifers, manifested by the gradual severity of the resulted environmental issues, the permanent irreversible depression of the water table, aquifer decompression, land subsidence in the Douz area, and contamination by petroleum flows, with 4 g/L of asphalt and 12 to 90 µg/L of cadmium in northern Kebili. Based on the assembled evidence, water scarcity has heavily influenced the equilibrium of these resources, and the adopted conservation plans have been insufficient to ensure economic incentives for environmental natural resources conservation (the annual average loss of fertile land is 1.25 ha). A detailed equilibrium analysis, relying on evaluating the water productivity-water exploitation ratio, is undoubtedly necessary for improving the integration among different decision makers. Moreover, a re-examination of the resulting impacts of the previously implemented strategies for reliable database development is the key to the successful handling of this transitory fragile situation.

Opis:: This paper is a continuation of the analysis of the grade of wear of the engine oil, used in the Caterpillar's marine engine, which is working in the engine's room of the harbour tug. Previous studies were related to the dynamic viscosity, lubricity and the grade of the metallic elements contamination. In these studies, the viscosity of the oil in most samples decreased with time of exploitation. However, in some samples, an increase of the viscosity was observed, what may indicate the fuel entering into the circulation of lubricating oil and its subsequent evaporation. Aim of this study is to determine the size of the Total Base Number changes and the flash point changes. The authors examine the changes in Total Base Number and the flash point of the exploited engine oil, in specified intervals in time between its exchanges. The results are analyzed and compared to the previously obtained results of the viscosity, lubricity and the grade of the metallic elements contamination. The analyses of the Total Base Number were conducted on the RST 822 Radiometer from Radiometer Analytical A/S, according to the polish standard PN-76/C-04163: Petroleum Products. Determination of the Total Base Number by potentiometric titration with perchloric acid. Flash point was determined using the Cleveland, in the open pot, using an ISL FP 92 5G device from Tusnovics Instruments Poland Ltd. The conclusions of this paper lead to better understanding of the processes, which occur in marine engines and its influence on the oil aging. Understanding of this process contributes significantly to a more accurate mathematical modelling of the aging process of engine oil.

Opis:: The aim of the study was to determine the effect of the application of different substances (nitrogen, compost, bentonite, zeolite and calcium oxide) to soil on its selected properties after prior contamination with heating oil: 0, 5, 10, 15 and 20 g kg^-1 d.m. of soil. Heating oil contamination and the application of different substances had a significant effect on the tested soil properties. In the series without additives, heating oil caused an increase in soil pH and a decrease in hydrolytic acidity, the total exchange bases and cation exchange capacity. Bentonite and calcium oxide had the strongest effect of all the substances on soil properties. They induced a rise in soil pH, an increase in the total exchange bases and cation exchange capacity and a decrease in hydrolytic acidity. The effect of other substances, particularly nitrogen and compost, on the tested soil properties was significantly lower. On the soil contaminated with heating oil, the effect of individual substances on the degree of base saturation was relatively small because it did not exceed 8% in all of the test series.

Opis:: The problem of engine oils and lubrication systems of marine diesel engines is an important issue in operation of engines. When considering the problems of exploitation of machines and devices, the lubricating oils are treated as one of the part of engine design, which should perform the functions: control friction between load-bearing surfaces, limit the temperature by carrying away heat from fluid fraction and fuel combustion, reduce corrosion etc. – general protect engine parts. The knowledge of the properties lubricating oils allows for proper selection them for the engine and correct use. During operation, the oil subjects' irreversible process of oil deterioration and it cannot properly fulfil their functions. Therefore important are frequent periodic checks of oil, it means monitoring. The state of the lubricating oil can be characterized by parameters such as viscosity, total base number, acid value, lubricating ability, flash point etc. Changes on these parameters of engine oil during exploitation, cause problems in fulfilling the primary functions of the oil. The target of the paper was the analysis and estimate of properties of trunk piston engine oil – Marinol RG 1240 after various times overwork on the sailing vessel “Dar Młodzieży” on the engine Cegielski-Sulzer 6AL20/24. The results were compared with the values critical and preventive limits and proposed several corrective actions for users the engine 6AL20/24.

Opis:: Celem badań było określenie wpływu zanieczyszczenia gleby olejem opałowym (0-20 g kg- 1 gleby) na zawartość węgla organicznego i przyswajalnych form wybranych makropierwiastków w glebie w warunkach aplikacji różnych substancji i uprawy roślin. Zawartości węgla organicznego oraz przyswajalnego potasu i magnezu w glebie były dodatnio skorelowane ze zwiększającymi się dawkami oleju opałowego, zaś w zawartości fosforu przyswajalnego nie wykazano ukierunkowanych zmian. Największy wzrost zawartości odnotowano w przypadku potasu. Zawartość przyswajalnych makroskładników w glebie była skorelowana z plonem i pobraniem pierwiastków przez rośliny. Substancje zastosowane w celu ograniczenia wpływu oleju opałowego na właściwości gleby wywołały najmniejsze zmiany w zawartości węgla organicznego, a największe w zawartości przyswajalnego potasu i magnezu w glebie. Bentonit spowodował, w porównaniu z serią bez dodatków, zwiększenie średniej zawartości przyswajalnych form fosforu, potasu i magnezu, a tlenek wapnia - zawartości przyswajalnego potasu i magnezu. Tlenek wapnia wpłynął także na zmniejszenie zawartości węgla organicznego i przyswajalnego fosforu w glebie. wpływ pozostałych substancji na badane właściwości gleby był mniejszy niż bentonitu i tlenku wapnia, a kierunek zmian w zawartości pierwiastków uzależniony od rodzaju zastosowanej substancji.

Opis:: Oil contaminations of soils are connected with human activity, for instance military activity. Organic pollution finding is one of environmental protection problems. Our field investigation was carried out to localize oil contaminations with induced polarization method (IP). The studied area is situated in post-Soviet military fuel base. The area is covered by postglacial sediments. Part of selected experimental area was submitted to bioremediation process. IP measurements indicated the relationship between bioremediation area and increase of chargeability effect. Two types of electrodes were used for measurements: stainless steel and non-polarizable ones. The survey results confirmed more accuracy of non-polarizable electrodes for postglacial area conditions. This method could be used to monitor efficacy of bioremediation process of hydrocarbons contaminated soils as well.

Opis:: A spectrum of low-frequency (20‒30 Hz) amplitude fluctuations of the ultrasonic (10 MHz) signal specularly scattered from water surfaces covered with monomolecular and thicker crude oil origin films of well-defined, oceanographically relevant viscoelastic properties was examined in laboratory and at-sea conditions. The relationship between the Surface water wave (30 Hz) damping coefficient and the oil layer thickness was established, and compared to the one predicted by the classical Stokes theory. The depression of the spectral energy density of wind-driven waves by surface films was inferred from the ratio of acoustic signal fluctuations spectra with/without films, and compared to that resulting from the Marangoni damping theory applicable to monolayers of particular surface viscoelasticity. The agreement between the theory and experimental data was satisfactory. As shown in at-sea experiments performed with a free-floating, buoy-like acoustic system, and an artificial oil slick spread over the Baltic Sea surface, the film’s rheological Surface properties can be recovered from acoustic surface probing, as well as oil spill edge detection. Simultaneous statistical analyses of the scattered signal amplitude distribution parameters turned out to be unequivocally related to the oil substance fraction weight, oil layer thickness, and the form of oil contamination.

Opis:: The purpose of the present experiment has been to determine the capability of maize (Zea mays L.) to uptake certain trace elements from soil contaminated with heating oil (0, 5, 10, 15 and 20 g kg^–1 soil) after soil amendment with neutralizing substances (nitrogen, compost, bentonite, zeolite and calcium oxide). The study relied on determination of the content of trace metals in plants. Incremental rates of heating oil caused depressed concentrations of copper and zinc, increased accumulation of nickel but did not induce unidirectional changes in the content of iron in maize. Bentonite was more effective than zeolite as a soil amending substance. Bentonite reduced the accumulation of three (copper, zinc, iron) and zeolite – just two (copper and nickel) of the analyzed elements in maize compared with the series without neutralizing substances. Application of calcium oxide and nitrogen to soil, in general, favoured the accumulation of the analyzed elements in aerial organs of maize.
Celem badań było określenie zdolności kukurydzy (Zea mays L.) do pobierania niektórych pierwiastków śladowych z gleby zanieczyszczonej olejem opałowym (0, 5, 10, 15 i 20 g kg^–1 gleby) po aplikacji do niej substancji neutralizujących (azotu, kompostu, bentonitu, zeolitu i tlenku wapnia), którą określono na podstawie badań ich zawartości w roślinach. Wzrastające dawki oleju opałowego przyczyniły się do obniżenia zawartości miedzi i cynku, wzrostu nagromadzania niklu i nie wywołały ukierunkowanych zmian w zawartości żelaza w kukurydzy. Bentonit był dodatkiem działającym bardziej korzystnie niż zeolit, gdyż ograniczał akumulację trzech (miedzi, cynku i żelaza) z badanych pierwiastków w kukurydzy, a zeolit tylko dwóch (miedzi i niklu), w porównaniu do serii bez dodatków. Aplikacja tlenku wapnia i azotu do gleby na ogół sprzyjała zwiększeniu nagromadzania badanych pierwiastków w częściach nadziemnych kukurydzy.

Opis:: In the article, changes in the properties of oils during operation were characterized. The main reason for this is the continuous aging process of the used oil caused by the interaction of oxygen contained in the air, which reacts relatively easily with hydrocarbons and the oxidation process is accelerated just by high temperature. Then the problem of microorganisms occurring in petroleum products and their effect on the properties of oils and the operation of the internal combustion engine was presented. The next part of the article presents effective microorganisms, i.e. what they are and how they work, in particular, their composition and appropriate development conditions. In addition, some of their specific applications were briefly described. In the next part of the article, the research methodology, applied oil samples with additives of effective microorganisms, both for fresh oil and used oil were described. In addition, the measuring test stand with instrumentation and measuring device was shown. The main part of the article contains the characteristics of dynamic viscosity as a function of temperature for fresh oil and used oil compared with oils with the addition of microorganisms in liquid form and ceramic tubes. The developed graphs enabled analysis of the effect of the addition of microorganisms on oil viscosity as ecological products.

Opis:: In the article, review of the literature on the subject currently used methods of controlling or limiting the development of microorganisms in petroleum products was made. The problem of microbial contamination in petroleum products was presented, which is still valid and is becoming more common. In the article, microbiological contaminants present in petroleum products were described. In the following part of the article the various methods of combating microbial contamination in petroleum products, which include physical methods, thermal disinfection and chemical methods were presented. In due to the limited use of physical methods, the article focused on methods widely disseminated. Combating harmful microorganisms using a biocide were described, which due to their harmful effects on beneficial microorganisms and the environment are becoming more and more limited use. Because of their harmful effects on beneficial microorganisms and the environment, their use is becoming more limited. Furthermore, another method of controlling microorganisms during storage of the fuel by means of cleaners that help to eliminate the water, reducing sludge was presented. Apart from the measures to combat microorganisms and additives of cleaning properties, the simplified methods for determining the amount of microorganisms in the fuel using the kits containing the finished substrate suitable for growth of microorganisms are described. These kits allow the monitor the status of microbial petroleum products and thus help prevent many crashes. In the final part of the article authors proposed other ways to control or limit microbial growth are presented. The work conclusions were completed. The most important is that there is a need to develop effective methods of combating microbial contamination of fuels and oils by means of measures environmentally friendly.

Opis:: The aim of this study was to determine the effect of neutralizing substances on the content of trace elements in maize on soil contaminated by heating oil. For the treatments without neutralizing substances, the dependency between increasing doses of heating oil and the cadmium content of plants was direct, yet the range of changes was relatively small. Under the influence of increasing doses of heating oil, the cadmium and manganese contents increased up to a dose of 10 g of oil per kg of soil, lead up to 15 g of oil per kg of soil and chromium within the full range of its doses, as compared to the control treatment (without heating oil). Higher doses of heating oil resulted in a decrease in cadmium, lead and manganese contents in maize. All of the tested substances had a significant effect on the content of trace elements in maize. Calcium oxide, zeolite and bentonite had a more pronounced effect than compost and nitrogen on the content of trace elements in this plant. A favourable effect, restricting the content of most of them in the maize was only observed for cadmium and manganese, in contrast to lead and chromium.

Opis:: The spreading properties of several hydrocarbons (vegetable, engine, gear and crude oils) on distilled and artificial sea water were determined under laboratory conditions using a novel optical method. With the aid of Langmuir’s equation, the geometrical signatures of a discrete lens of each hydrocarbon droplet floating on a water tank served to calculate the entering E (31.30–94.18 mN m−1) and spreading S (−3.50 to −57.49 mN m−1) coefficients, and equilibrium thicknesses t∞ (0.20–1.25 cm). They appeared to be in agreement with the values derived from direct interfacial tension measurements (Wilhelmy plate and stalagmometer methods). Empirical relations of the normalized lens radius rL/rdrop and S on the water surface tension γAW were postulated as being of significant value in oil spill assessment studies at sea. The parameters obtained together with the surface properties of a natural surfactant-containing water body represent the principal input data required for modelling the spreading of a surface-tension-gradient-driven oil spill at sea.

Opis:: The analysis of ecological hazards on soil pollution by oil products has been provided in the impact zone of the railway. The results of oil product migration in soils in the area of influence on section Lviv–Khodoriv are given. To study this problem, a method was used to take soil samples according to the standard DSTU ISO 10381-4: 2005. To determine the content of petroleum products used the method MVV No. 081/12-0116-03 Pochvy. Based on the results of the study it was found that contamination with petroleum products in the study area exceeds the norm in the area of influence of the railway at a distance of 5 to –50 m on average 3.5 times. It is proposed to make management decisions to prevent violations of the sanitary protection zone of the railway and the placement of agricultural plots on it. For rehabilitation of contaminated soils, it is advisable to use a natural sorbent – glauconite, which is widespread in the bowels of Ukraine. The adsorption capacity of glauconite relative to diesel fuel has been experimentally established. According to our experiments it is proved the high efficiency of the proposed sorbent, which is 90%. Therefore, in the future it is necessary to periodically monitor the condition of the soil in the area to prevent pollution. This study proves that this practice is necessary.

Opis:: The paper deals with water conditioning issues in oil-field development using water-flooding. It is common knowledge that injected water contains oil residues and mechanical impurities, which affect permeability of geological horizon. It has been shown that these water impurities could intensify rock colmatation up to a full clogging of pores and fractures. Hence, issues of improving quality of injected water, aimed to ensure enhancement of reservoir properties, have been studied from a variety of new angles. There are given results of conducted test experiments as well as detailed description of elaborated equipment design. It has been established that two-stage treatment technology proposed in the paper, by making use of magnetic treatment device and sewage tank with liquid hydrophobic layer, will allow to considerably improve quality of injected water. Suggested water treatment unit appears to be highly applicable, providing a maximum effect at a minimum material cost.
