ABSTRACT
The paper examines the results of oil pollution field observations carried out from 2007 to 2014 on the Black Sea coast in the area of oil terminals of the city of Novorossiysk, which is the most important oil port of Russia. The present study included visual assessment and sampling of oil slicks and sediment cores. The analysis of samples were carried out with the use of thin layer and column chromatography, optical and gravimetric methods making possible to determine separately the sum of saturated, mono- and di-aromatic hydrocarbons (HC), the sum of polycyclic aromatic hydrocarbons (PAH) and the sum of asphaltic components (AC) as well as the presence of hydrocarbons of contemporary biological origin. The data on the concentrations of hydrocarbons, PAH and asphaltic substances in the coastal water and sediment cores under different hydrometeorological conditions, the distribution and the composition of oil slicks found on the shore are considered and analyzed. The evidences of high level and chronic character of oil pollution of the coastal zone are presented. The natural and anthropogenic factors influencing the distribution of oil components are revealed.
