Natural bituminoids in soils of the forest zone: Luminescence diagnostics and content levels (Satino Research Station,Moscow State University)

The levels of content, luminescence parameters, and composition of PAH bituminoids successively extracted with hexane and chloroform from different soil types of the forest zone beyond the impact of industrial technogenic factors were studied. It was found that the content, composition, and properties of bituminoids varied depending on total organic matter in the genetic horizons of soils and their landscape-geochemical positions. Geochemical and diagnostic features of natural soil bituminoids were determined. A difference was shown between the luminescence properties of soil bituminoids and those of oil products.
