Abstract
The paper presents the results of applying the methodology of chemical fingerprinting to survey the territories of industrial and natural objects, environmental accidents and objects of accumulated environmental damage in various regions of Siberia, including the Arctic zone of Russia. The data obtained by GC/MS using the capabilities of targeted and survey ecological analysis are presented. Polycyclic aromatic hydrocarbons, polychlorinated biphenyls, various classes of hydrocarbons, including relict oil biomarkers, chloro- and methylphenols, Cl-, N-, S-, O-organic compounds of various classes were considered as pollutants. The most important tools of chemical fingerprinting are considered, and it is shown that the use of a set of data on marker compounds of various types, diagnostic ratios of characteristic compounds, multi-vector chromatographic profiling of characteristic compounds ("fingerprints") makes it possible to establish the origin of pollution sources with a high degree of probability.
