More Information
Summary:The qualitative and quantitative composition of polycyclic aromatic hydrocarbons (PAHs) in tundra soils has been studied by gradient high-performance liquid chromatography. The differentiation of the PAHs in the soil profile is of clear accumulative character. The pool of polyarenes in the soils is determined by the cryogenesis processes and mainly consists of low-molecular-weight bi- to tetranuclear PAHs, the high-molecular-weight PAHs in the organic horizons make up no more than 20% of the total polyarenes in the soil, and penta- and hexanuclear structures are almost absent in the mineral layer.
