Opis:: According to many intenstigations, oil pollution cause difficult changes of structure and function of natural ecosystems, as well as violation of metabolic processes, production and destruction of organic matter, and consequently leads to a decrease in species diversity. Studies show that planktonic animals are quite sensitive to oil pollution of sea water, which accelerates their death in the concentration of 0.01 mg·dm^-3.

Opis:: The peculiarities of sanitary and hygienic rationing of the oil products content in environmental components were analyzed. It was established that the general ecological situation in our country and abroad is unsatisfactory and the issue of finding modern methods of standardizing the quality of environmental components, which would cover the indicators and criteria of their composition and properties, is becoming increasingly urgent. Together, it would ensure ecologically sustainable development of the biosphere in all hierarchical levels of its organization. It was established that such an assessment system does not exist today and therefore, there is no generally accepted universal method for assessing the quality of the environmental components. For this purpose, it is necessary to develop a methodology, in particular a method of biotesting, which will provide a generalized qualitative assessment of the ecological state of the environment, without being based on the quantitative characteristics of the MPC. The possibility of applying a new method of phytotesting of soil that was artificially contaminated with different types of petrochemicals in different concentrations per unit volume of soil using flax seedlings (Linum usitatissimum L.) was investigated. The growth characteristics of the test plants grown on artificially contaminated soil with petroleum products were presented. In the course of research, the possibility of studying the effect of petrochemicals on plants directly in artificially contaminated soil was confirmed. On the basis of the analysis of the obtained results, it was found that when the soil is contaminated with oil products, the aviation fuel has a greater impact on the shoots, whereas gasoline and diesel fuel have a lower impact on the roots in lower concentrations. At higher concentrations, their depressant effect is almost equal.

Opis:: Drilling sludge formed in the process of drilling wells using a drilling agent on a hydrocarbon basis looks like soft pasty mass of black color, with a distinct smell of petroleum products. Oil-based drill sludge has a high oil and chloride ions content, identified excessive concentrations of chromium 2.67 times. According to the degree of accumulation of heavy metals, that were distributed in the following order: manganese (Mn) > zinc (Zn) > copper (Cu) > chromium (Cr) > lead (Pb) > cobalt (Co) > arsenic (As) > mercury (Hg) > cadmium (Cd). The results of the particle size distribution indicate a significant proportion of physical clay, which peaks for the silt fraction – 63.60 %. During the study of the waste drilling agent was found that it includes oil products which reached level of 9000 mg/kg, while the hydrogen index refers to a neutral medium – 6.5 pH. The evaluation of the toxic effect of drilling waste according to the test-results has an acute toxic effect on the environment (hazard class IV). The significance of the research indicates the relevance of environmental assessment of drilling waste for the optimal choice of their subsequent disposal.

Opis:: Experimental studies on the dynamic sorption of model mixtures containing petroleum products were performed. The subject of the study was the modified sorbent from the ash-and-slag wastes accumulated in the ash dump of the Novocherkassk State District Power Plant (SDPP) (Russia, Novocherkassk, Rostov Region), obtained using the method of ash removal. The quantity of the sorbent for each model solution was fixed at 5.0 g. The model solutions in the amount of 1 dm³ were passed through a column filled with the modified sorbent at constant filtration rate w = const with filtrate takeout of 0.1 dm³/min. The pH value of the solution, which is advisable for extracting petroleum products, was determined experimentally. For this purpose, the model solutions, containing 100 mg/dm³ of petroleum products with pH = 1.65, 4.01, 6.86, 8.12, 9.18, and 11.34, were prepared. The optimum pH value of the solution was considered pH = 7.5. The content of petroleum products in the filtrate in all experiments was determined using IR spectrometry. The working range of water pollution with petroleum products was determined on a series of model solutions containing petroleum products in the range between 0.5 and 10 mg/dm³ with the increment of 0.5, between 10 and 100 mg/dm³ with the increment of 10, and between 100 and 1,000 mg/dm³ with the increment of 100. The maximum extraction of petroleum products from the solution was 88.23%. The applicability of the Henry’s law to the range of petroleum products concentrations in the filtrate of 50 mg/dm³ was confirmed. The adsorption equilibrium constant (Henry’s law constant) was determined experimentally. The effect of the natural freshwater matrix on the degree of petroleum products extraction was studied; no significant effect on petroleum products sorption was found. A conclusion was made that the sorbent can ensure the efficiency of water purifying from petroleum products of no less than 85% in the range of pollution between 5 and 300 mg/dm³.
