Sažetak
Leaching of trace elements from industrial waste is the main mechanism of contaminant transport from waste to the environment [1]. Oxyanions (As, Cr, Mo, Se, S, V) are of particular concern if the waste is alkaline as they are the most mobile in those conditions [2]. An aged alkaline waste, located in Istria (Croatia), was generated in the second half of the 20th century during Raša coal combustion [3] and has caused pollution of the local area [4]. Aged waste has different characteristics compared to the waste disposed of [5]. Therefore, leaching of oxyanions was tested on the surface samples that have signs of early pedogenesis. Considering that several extract concentrations of analyzed oxyanions were above the regulatory limit, the waste still poses a threat to the local area, even decades after disposal (fig.1.). The mineralogical analysis showed that mineral transformation occurred due to exposure to environmental conditions, changing the mobility pattern of several elements.
