Saturated hydrocarbons in the background and contaminated soils of the cisurals

摘要

A homologous series of n-alkanes (C-20-C-35) was identified in peaty-podzolic-gleyic soils. Structures with odd numbers of carbon atoms (C-25-C-35) were predominant in the soil organic matter. It was found that the major amount of both odd and even n-alkanes was accumulated in the peaty litter. In the mineral horizons, the mass fraction of the odd n-alkanes abruptly decreased to become comparable to that of the even n-alkanes in the soil-forming rock.
