Abstract
Seven samples of plankton from the Beloe Sea sampled at the 〈〈Ecolog-2002〉〉 research ship trip were analyzed by the SR XRF method. Measured XRF spectra were processed with the help of an algorithm accounting matrix effects of element interaction. SR XRF results together with high-resolution atomic-absorption and neutron-activation data allowed to determine concentrations of 43 chemical elements in plankton. Comparison with bottom sediments allowed us to calculate enrichment coefficients EF; plankton from the open ocean margin (Beloe Sea) concentrates Br, I, Cd, Zn, Cu, Cr, As, Pb, Se, Sn, Hg, Sb in different degrees (EF from 1000 to 10).
