Concentrations of aliphatic hydrocarbons and hexachlorocyclohexane isomers in under-ice water, snow, and sea ice from the Greenland Sea

Data on concentrations of aliphatic hydrocarbons and isomers of hexachlorocyclohexane in specimens of various natural environments (water, snow, and ice) of the Greenland Sea obtained during field studies on the ice breaker Otto Shmidt are presented. Analyses were carried out with gas chromatographs using capillary and packed columns. Concentrations of aliphatic and chlorinated hydrocarbons were higher in snow and ice specimens than in sea water and were also higher in less saline water beneath ice. It is concluded that pollutants in this ocean area are at the background level.
