 abstract={The results of the first (since 1939) investigation of Gliwice Channel have been presented. The concentrations of mobiles and constant forms of heavy metals in the bottom sediments have been given. The changes range was: for chromium 4.8-463.2 mg Cr/kg, for cadmium 0.6-18.2 mg Cd/kg, for lead 4-197 mg Pb/kg, for cupric 6-2152 mg Cu/kg, for manganese 33-1664 mg Mn/kg, for nickel 5-85.2 mg Ni/kg, for zinc 64-2244 mg Zn/kg, for iron 2080-94080 mg Fe/kg. The percent participation of stable forms of chromium decreases during longitude profile of canal whereas participation of mobile forms is increases. The stable and mobile forms of cadmium (Cd) increase. The concentrations of stable and mobile form of lead (Pb) decrease. The percent participation of stable forms of copper (Cu) is high (82- 100%). On total longitude of canal the participation of mobile forms of manganese (Mn) increases, but stable forms have advantage. For nickel (Ni) the stable forms are prevail too (form 55% to 81%). The participation of mobile forms of zinc (Zn) is 18% to 60%. The sharply outlined relationship between metals and organic matter concentrations indicates the significance in the metals transport processes from water to bottom sediments. Consequently, pollution of bottom sediments by heavy metals is the secondary result of organic substances of water enrichment. The relationships between total metals and iron (Fe) concentration points to the role of heavy metals stable amalgamations with amorphous ferric oxides. The cascade character and pulsatory water flow of Gliwice Channel makes the concentrations of heavy metals in bottom sediments successfully decrease in each canal section. At the same time, in each section of the canal gradual increase in metals concentration occurs and the maximum values for all determinated metals are present just before sluices closing sections. The best ecological effect, from the economical point of view, is obtained by bottom sediment removal on the about 1 km sectors over each of the sluice.},
