T1 Chemical Composition of Bottom Sediments and the Zoobenthos of the Daugava River JF Hydrobiological Journal JO HYD YR 1998 FD 1998-06-01 VO 34 IS 2&3 SP 59 OP 65 AB Bottom sediments and macrobenthos communities of the Daugava River were studied to assess its pollution with heavy metals (Cd, Cu, Co, Pb, Ni) and organic substances. A certain relation was revealed between concentrations of pollutants, on the one hand, and the organic carbon content of sediments and the composition of the zoobenthos, on the other. It was found that bottom sediments can serve as reliable indicators of pollution. PB Begell House LK https://www.dl.begellhouse.com/journals/38cb2223012b73f2,53d678a4271bcc7d,510c35ee4e124e10.html
