摘要：

Eight samples of stratified bottom sediments (cores) from the Gdansk Basin, the Bornholm Deep, and the Arcona Deep (Southern Baltic) were collected. The rate of sediment accumulation amounting to 0.1-2.3 mm/y was established by means of the radioactive lead (Pb-210) method and confirmed by Cs-137 distribution. The measurements revealed an increase of some heavy metals concentrations in the surface sediments. The enrichment factors for Hg, Cu, Zn, Pb, Cd, Ni, Co, and Cr were found in the ranges of 4.7 - 4.9, 1.1 - 2.7, 1.1 - 2.5, 1.4 - 2.8, 1.0 - 2.2, 1.0, 1.0, and 1.0- 1.2, respectively. An increase of metals inflow to sediments caused by anthropogenic factors, modified by oxidative-reductive conditions, is held responsible for the enrichment.
