Abstract
It was shown that the use of methods of chemical analysis of oil-contaminated soils recommended for environmental control, showed no more than 50% of the mass of oil introduced into the soil, even in freshly contaminated samples. It was found that main errors were associated with the loss of light oil fractions during drainage of contaminated soil samples, incomplete extraction of pollutant oil from soils, ignoring high-molecular polar oil fractions, resinous and asphaltenic fractions when using these methods. A slight modification of the applied preparatory analytical methods was proposed, wich consisted in replacing the cold extraction of contaminated soil with a hot one, followed by additional weighing of the extracted chloroform prior swing absorption to assess the content of oil products, as well as soil samples for extraction at a natural moisture level without air- dry preconditionning. It was concluded that these changes significantly reduce analytical errors and increase the reliability of monitoring soil pollution during crude oil spills, as well as the effectiveness of rehabilitation actions.
期刊介绍：
The Journal "Ekologia i promyshlennost Rossii" («Ecology and Industry of Russia») is aimed to promote acquaintance of the world scientific and technical public and specialists, interested in the problems of the environment protection, with advanced achievements of the science and engineering practice on securing of stable (self-supporting) evolution within the limits of the United Nations accepted recommendations (RIO 92 and RIO+20). A circle of papers includes basic researches and engineering decisions, analytical and methodical operations, reviews on journal subjects. The journal lays special emphasis on methodical elaborations, analytical investigations in the sphere of creating the ecological culture of the population, to the features of ecological education in higher schools of the country for the sake of actualization in specialists'' consciousness of the scientific necessity to know environmental problems of the modern civilization and paths of their settlement. Original papers and investigations of scientists and specialists on separate themes occupy an independent niche of issues under the «Cover story» heading. The journal task is to promote practical implementation of scientific and engineering decisions in the field of decrease of anthropogenic load on the biosphere and environment protection (open lectures, round tables, discussions and so forth). Ecology and Industry of Russia is an informational reference book about the newest developments of the Russian and foreign scientists and the companies realized in Russia, the CIS and Baltic countries, and far-abroad countries. The journal publishes information reports about holding in Russia and abroad the international, all-Russian and regional congresses, conferences, and symposiums related to the journal subjects.
