Application of geochemical and ecotoxicological Indices for assessment of trace elements contamination of the Vistula River Valley in the Małopolski Gorge. Geomorfological-geochemical approach.
During the field investigations, 192 sediment samples were collected for laboratory analysis. The data contain granulometric composition (areometric method), organic matter (loss-of-ignition method at 450⁰C), carbonate (Scheibler method), and iron content (iodometric method) and concentration of trace elements (the samples were washed through a plastic sieve with a mesh diameter of 1.0 mm, air-dried samples were dissolved in a solution of H2O-HF-HClO4-HNO3 (ratio 2:2:1:1), concentrations of trace elements (Cu, Pb, Zn, Ni, Co, As, Sr, Cd, Cr, Ba, Fe, Al) were determined by the ICP-OES and ICP-MS method at Acme Labs (Bureau Veritas Commodities Canada Ltd)).
The data also contain calculations of geochemical indices (EF, Igeo, PI, CF, Cd, PISum, PIAvg, PINemerow, PLI, ER, RI).
