Abstract
The issue of identifying pollutant accumulation areas in Barents Sea sediments was considered based on years-long research (2002–2018) conducted by PINRO. GIS technology and geostatistical analysis of data on the contents of heavy metals and organochlorine compounds were used in the research. The total rated values of contents for Cu, Ni, Pb, Zn, Cr, Hg, HCB and the total HCH, DDT and PCB in sediments was used as the general rate of pollution and identify concentration areas. The values were rated in accordance with the arithmetic mean for each pollutant accumulated in sediments. The mean of the total pollutants counted against the interpolation model was suggested as the criterion to identify technogenic pollution accumulation areas. The research distinguished three major heavy metal pollution accumulation areas in the Barents Sea. It was concluded that pollution enters an accumulation area in different ways. Glacial melting in Arctic archipelagos as a result of global warming over the last two decades is likely one of the main pollutant vectors.
