Description	Three distinct sedimentary sequences (S1, S2, andS3) were identified. The basal sequence S1 represents original Morava river channel sediments deposited before the 1930s. The overlying sequences S2 and S3 represent a post-1981 dredging sediment wedge, which progrades into the lake.137Cs dating revealed a distinct Chernobyl 1986 peak at 150 cm depth inferring sedimentation rates up to 7.7 cm/year. Sediment contamination abruptly increased from the pre-1930s deposits to the post-1981 deposits by two to five times for Pb, As, Zn,and Cu, about 10 to 15 times for Cr, Sb, and Hg, up to34 times for Cd, and 25 to 67 times for DDTs, PCBs,and PAHs. The concentrations of most contaminants remained approximately constant until the late 1980s when they started to decrease slowly. The decreasing trends were most prominent for heavy metals and anthracene, less prominent for DDTs, and almost absent for PCBs and most PAHs.
