Accuracy of the procedure was confirmed by analysis, based on the German Standard Method DIN 3814-S4, of
water lixiviates from three overbank sediment samples collected in two abandoned mining areas. The
attained results were compared with those obtained by inductively coupled plasma (ICP) techniques, and
acceptable agreement for elements with ZN20 was found. This study highlights the possibility of using a
simple methodology for analysis of liquid mining samples using the WDXRF technique, commonly employed
for geochemical exploration of solid samples in environmental studies.
