Abstract

The article deals with the determination of mobility of selected risk elements in soil samples of thermally active dump resulting from
mining activities in the Ostrava region. The samples were taken from Hedvika dump during 2017 to 2018. Extraction of soil samples
was performed using three-step sequential extraction of BCR (Bureau Community of Reference). Sequential extraction can provide
information about the processes that normally take place in the environment. The solid soil component is gradually leached in the
various extraction agents from the weakest to the strongest. This provides information on the total amount of risk elements potentially
available under specific environmental conditions. Selected risk elements (Cr, Cu, Ni, Zn) were determined by ICP - MS method (Inductively coupled plasma mass spectrometry) and AAS (Atomic absorption spectrometry) (Zn). Nitric acid leaching was performed to
supplement the total BCR extraction analysis.
