Indicator Ratios of Polycyclic Aromatic Hydrocarbons for Geoenvironmental Studies of Natural and Technogenic Objects

The role of polycyclic aromatic hydrocarbons (PAHs) in geoenvironmental studies is demonstrated. Indicator ratios used to identify PAH origin are considered. Their reliability is assessed for natural and technogenic objects, taking into account their stability in the environment and the specific natural conditions. The most accurate indicators are determined for identifying combustion products of domestic and medicinal wastes.
