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.

原油泄漏情况下土壤修复技术的污染水平和有效性评估

结果表明，使用环境控制推荐的油污染土壤化学分析方法，即使在新污染的样品中，也不超过50%的油引入土壤。结果发现，这些方法的主要误差与土壤样品排水过程中轻质油馏分的损失、土壤中污染物油的提取不完全、忽略了高分子极性油馏分、树脂和沥青质馏分有关。对应用的预备分析方法进行了轻微修改，其中包括用热萃取取代污染土壤的冷萃取，然后在摆动吸收之前对提取的氯仿进行额外称重，以评估油品的含量，以及在自然湿度水平下提取的土壤样品，而不进行空气干燥预处理。结果表明，这些变化显著降低了分析误差，提高了原油泄漏时土壤污染监测的可靠性和修复措施的有效性。

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.
