Regularities of oil pollution redistribution in different types and mechanical fractions of soils
The work is devoted to the study of oil and petroleum products falling into the environment in order to estimate their quantity, as well as individual characteristics. The latter task is most difficult, because the natural environment contains a large number of various organic components, some of which can give an analytical signal very similar to the individual characteristics of petroleum products. In work on the example of the analysis of ranges of a luminescence use of a method of recognition of images for the solution of problems of identification of oil products in soils is considered. On the basis of digital coding of ranges of a luminescence regression dependences of intensity of spectral maxima on the size of granulometric fractions of various types of soils are constructed. In work it is established raised the content of polycyclic aromatic structures in small fractions of soils in comparison with large fractions. In small granulometric fractions of soils the critical transition which is expressed in sharp increase in polycyclic aromatic structures in the range of mechanical structure of soils from 0,5 to 1,0 mm is observed. Soil fractions of such a mechanical composition, regardless of morphology, should be especially closely monitored in monitoring emergencies in the event of possible accidental spills of oil products.
