Oil and its distillation products play an important role in human life. In the process of distilling oil, we get important products for the life of a modern person. It is hard for a person to live without gasoline, diesel fuel, lubricants and polymeric materials. The chemical industry is also heavily dependent on oil. Oil production makes a significant contribution to the economy and at the same time causes significant damage to the habitat of humans and animals. Nowadays the oil production process may cause oil spills into the upper soil layers and water bodies. Also, the likelihood of accidents during the production, transportation and distillation of oil is not excluded. Most accidents occur due to corrosion of pipes, which are not always inspected and replaced in due time. Each pipeline has its own service life, oil companies are required to monitor the condition of pipes, valves, etc. It is necessary to create special commissions to control the transportation routes. It is always better to prevent an accident than to clean up the spill and clean the environment from pollution products. Unfortunately, the leaders of large oil corporations do not want to replace pipelines in time, trying to save some material resources. As a result, animals, birds and inhabitants of reservoirs die. Not only adult representatives of the animal world can die, but their embryos, they are very sensitive even to a small amount of oil and its products. Animals listed in the Red Book are dying. Every year more and more representatives of flora and fauna suffer from human mistakes. Some species are on the verge of extinction. A man in pursuit of technological progress ruins his habitat. A large number of oil fields are located at the bottom of reservoirs, as a result, we have oil spills during production at the bottom and surface of the reservoir. The effect of these processes on fish is almost always lethal. Birds, during migration, are also exposed to the detrimental effects of oil spills. Oil contaminates their feathers and enters the respiratory tract. As a result, contaminated feathers do not allow to continue the flight.

Oil decontamination of water bodies is one of the most complex and time-consuming tasks in the field of liquidation of oil spills. The complexity of cleaning natural water bodies is associated with a dynamic water environment and a variety of oil transformation processes that occur in the water. The most advanced and developed are technologies and methods of collecting oil and oil products from the surface of water bodies. Economically acceptable and well-grounded technologies for oil decontamination of bottom sediments are presented in minimal quantities, and often are not applicable to natural water bodies. The technology for oil decontamination based on flotation has been developed and successfully applied on Lake Shchuch'ye in 2004–2005 and showed a positive result after two summer seasons of work. This article presents the results of aquatic ecosystems recoverу as a result of oil decontamination of bottom sediments. The issue of restoration of the aquatic ecosystem as a result of cleaning bottom sediments from oil after a considerable time interval has been studied. A comparison of the quantitative indices and species diversity of the zooplankton of Shchuch'ye Lake from 2004 to 2016 showed a clear tendency of increasing the abundance, biomass and species diversity of total zooplankton and Cladocera in particular. In 2016 the amount of zooplankton species of Shchuch’ye Lake reaches the number of species of the uncontaminated lake, using as a control. It was shown that the macrozoobenthic fauna of Shchuch'ye Lake is poorer in both the number of main ecological groups and in species diversity within certain groups characteristic than in the uncontaminated lake. Some groups were found in both lakes, but the species diversity of Lake Shchuchye was poorer. The exception was a group of leeches, which had a greater variety in Lake Shchuch'ye. The change in the oligochaetene complex to chironomid, both in numbers and in biomass, indicates an improvement in environmental conditions, since chironomids are more sensitive to the quality of the habitat. Chemical analysis of bottom sediments in 2016 revealed that the oil concentration did not exceed 0.9 mg / kg, which indicates the effectiveness of the oil decontamination technology of bottom sediments.

Работа посвящена теме устранения загрязнения акватории морей нефтепродуктами в условиях сложной ледовой обстановки. Приведены различные способы очистки водных пространств от нефти и нефтепродуктов, дан сравнительный анализ их особенностей и недостатков. Описана проблема очистки водоемов от нефтепродуктов при наличии колотого и сплошного льда. Предложена новая технология использования сорбента в таких специфических условиях. Представлена сконструированная авторами установка, которая подключается к стандартным судовым системам и позволяет без их затратной модернизации эффективно бороться с нефтеразливами в низкотемпературных широтах. Ключевые слова: новая технология использования сорбента, арктический шельф, боновые заграждения, разлив нефти, диспергенты, сорбент, пульпа, струйный смеситель : This work is focused on the problem of eliminating the pollution of the seawater with oil products in difficult ice conditions. Various methods of cleaning water spaces areas from oil and oil products are presented, and a comparative analysis of their features and disadvantages is given. The problem of cleaning water bodies from oil products in the presence of crushed and solid ice is described. A new technology for using the sorbent in such specific conditions has been proposed. An installation designed by the authors is presented, which is connected to standard ship systems allows to effectively deal with oil spills in low-temperature latitudes with no need for high-cost modernization. Keywords: Arctic shelf, booms, oil spill, dispersants, sorbent, pulp, jet mixer

The article describes the dangerous consequences of petroleum products - the most dangerous pollutants of the aquatic environment, which disturb many natural processes and relationships, changing the habitat of aquatic organisms.A variety of sources contributes to the pollution of natural waters with various fractional composition of petroleum products. The complex studies of oil pollution of water bodies were carried out in the vicinities of Astrakhan in places of accidental oil spills in 2013-2015. Analysis of the study results confirmed the need to assess the extent of water pollution by hydrocarbons, not only in terms of the mass concentration of oil in the water, but also in biological parameters of the harmless concentration of the toxicant, because under equal levels of mass concentration oil contaminants with different fractional composition have different degree of toxic effects on living organisms. The heavy oil fractions of the oil products had the maximum effect on Daphnia magna Straus. The limit of harmless concentration of oil products dissolved in natural waters of the Serebryanaya Volozhka canal was 0.034-0.136 mg/dm3; the limit of harmless concentrations of oil products spilled on the water surface made 0.014 mg/dm3. This is 3.6 times less than maximum permissible coefficient of oil products in the water bodies of Russia (0.05 mg/dm3). Bioassay methods, along with the traditional analytical methods have to be used in a comprehensive study of oil pollution of the aquatic environment.

Nutrient applications are often required to meet Florida’s demand for agricultural and horticultural commodities, but often those applications occur in close proximity to water bodies. In order for scientists, policy makers, and citizens to make decisions regarding nutrient issues in Florida, it is important to first understand which markets contribute to Florida’s fertilizer consumption. This three-page fact sheet explains Florida’s fertilizer usage statistics. Written by T.W.Shaddox and published by the Environmental Horticulture Department.­http://edis.ifas.ufl.edu/ep541
