USE OF ENRICHMENT, AND CONTAMINATION FACTORS TOGETHER WITH GEOACCUMULATION INDEXES TO EVALUATE THE CONTENT OF CD, CU, AND NI IN THE RYBNIK WATER RESERVOIR IN POLAND

In this paper, the contamination degree of the Rybnik Reservoir with c admium, copper and nickel was analyzed. Quality of the water from the reservoir was determined by drawing comparisons between the metal cont ent in the water and both the officially permitted levels (contaminati on factor) and levels of metals occurring in the water of non-contamin ated areas (enrichment factor). Contamination of bottom sediment with chosen metals was analyzed with reference to the metal content in muds tone (geoaccumulation index, enrichment factor, contamination factor). Trends towards changing the metal content in the bottom sediment was analyzed by determining the enrichment factor of the surface layer of the bottom sediments in relation to a deeper layer. Enrichment of the bottom sediments with metals coming from the water was also determined .
