Trace elements concentration (surface and subsurface samples) in the floodplain sediments at the mouth of the Nysa Kłodzka River into the Oder Valley

During the field investigations, 44 sediment samples were collected for laboratory analysis - 22 surface samples and 22 subsurface samples. The data contain concentration of trace elements (the samples were air-dried, crushed (≥70% passing 2 mm) and pulverized (250 g; ≥85% passing 75 μm) then were subjected to a modified aqua regia digestion (HNO₃:HCl:H₂O at a ratio of 1:1:1), followed by inductively coupled plasma emission and mass spectrometry (ICP-ES/MS) at Acme Labs (Bureau Veritas Commodities Canada Ltd)).Reporting Detection Limits were: 0.1 ppm for Cu, Pb, Ni, Co and Cd, 0.5 ppm for As, and 1 ppm for Zn, Sr, Cr and Ba.
