摘要：
Dynamics of the molecular composition of polycyclic aromatic hydrocarbons (PAH) in soils located within the contamination zone of the Astrakhan gas-condensate plant is characterized. Over a two-year period of plant operation, the content of technogenic PAH structures increased 10- and 100-fold in soil horizons. It was found that the ratio of the amount of complex alkylated pedogenic phenanthrenes to the amount of bare-nuclear technogenic PAH may serve as one of the indices of the status of soil ecosystems.
