title: Content and Composition of Hydrocarbons in Water and Sediments in the Coastal Regions of the Russian Sector of the Black Sea
abstract: The current level and origin of hydrocarbons (HCs): aliphatic (AHCs) and polycyclic aromatic (PAHs) were determined (September 2021 and May and September 2022) in suspended particulate matters (SPM) of surface waters (for AHCs, 20 µg/l; for PAHs, 130 ng/l, fluorescent method) and in bottom sediments of the coastal areas of the Caucasian sector of the Black Sea of the Russian Federation. Despite a decrease in the HC concentrations in the surface waters in recent years, the most polluted areas inc
