Abstract:

Total concentration of lead and its individual partitioning, i.e. exchangeable, adsorbed, organically bound, carbonate, sulfide and residual have been assayed in the bottom sediment of Rybnik reservoir applying AAS. The contribution of particular fractions to the total lead concentration was as follows: carbonates (37%) > sulfides (28%) > residual (14%) > adsorbed (10%) > exchangeable (8%) > organic bonds (3%). The multiple regression analysis applied led to the conclusion that the increase in lead content in the bottom sediment resulted from an increase in poorly mobile forms, notably carbonates.
