Abstract: Chemical analysis of sediments provides an efficient tool for water quality management. Ten sediment samples collected in 2008 from two locations situated in the Danube Delta Biosphere were analyzed in a comparative study of mobile metallic elements via two different pre-treatment techniques: air-drying followed by sieving and wet sieving. The experimental data proved that air-drying procedure produces drastic changes in mobility of the metallic elements from the sediments which were studied as an effect of the oxidizing conditions. Wet sediment or oxygen-free dried sediment is recommended to be used in environmental studies regarding determination of mobile fractions from sediment samples.
