Abstract

140 ice samples were collected in Greenland during the summer of 1993. in a preliminary study, polycyclic aromatic hydrocarbon (PAH) concentrations were measured in 12 samples. Very careful work was needed in order to prevent any contamination. HPLC with variable wavelengths fluorimetric detection was used to determine concentrations in the 1-1000pg kg(-1) ice range. PAHs are good tracers of all types of combustionand the variation of their concentrations shows the evolution of pollution by organic matter produced by coal and fuel combustion (fluoranthene and phenanthrene), motor vehicles (benzo ghi perylene) and forestfires (retene). The global trend shows that the contamination by coaldecreases, that the contamination by fuel increases, but that the total amount of PAH deposited on the ice sheet in polar regions is constant since the beginning of the industrial period.
