Oil pollution in the Caspian Sea coastal waters

The study aims to investigate hydrocarbon and pollutant concentrations in the southern coastal waters of the Caspian Sea to trace their origins and nature, including the effect of the beach materials on hydrocarbons for 11 sites in Golestan, Mazandaran, and Guilan provinces. Samples were collected from sandy and rocky sites for gas chromatography in five carbon ranges of gasoline, diesel oil, engine oil, BTEX, and PAH. The GC analysis revealed the highest pollutant concentration levels in autumn and the lowest in summer; moreover in rocky beaches analysis indicated that a major portion of the oil pollution in the region consists of hydrocarbons.
