Abstract
The aim of this study is to present a spatial distribution of As, Sb, and Tl in topsoil and subsoil in the Kavadarci region, Republic of Macedonia. In total, 344 soil samples were collected from 172 locations (0–5 cm and 20–30 cm) in an area of 360 km2. ICP-MS was applied for the determination of the invesgated elements. It was found that the highest contents of As, Sb, and Tl were on Holocene alluvium of the river Crna Reka, where average concentrations exceeded the average of the total investigated area by two times for As, three for Tl, and more than five times for Sb. The enrichment of the Holocene alluvium of the river Crna Reka is supposed to be a consequence of natural erosion from Allchar mine deposits on Kožuf Mountain and also from mining activities in the past.
