Abstract
The essence of karst landscapes is considered. The content of Cu, Zn, Pb, Cr, Ni, Co, Mn, Cd trace elements in the soils of karst landscapes in the Ponor, Vrachanska and Vlahina Mountains, as well as those in The Western and Middle Fore-Balkan (Arbanassi Plateau), Bulgaria, is analyzed using landscape-geochemical, laboratory, mathematical and statistical methods. The obtained results are compared with the average content in the carbonate rocks of Bulgaria (Kuikin et al., 2001), the rendzina (Rendzic Leptosols, LPk, FAO) and the gray forest soils (Haplic Luvisols, LVh, FAO) in the country (according to Atanassov et al., 2002). The importance of the carbonate rock substrate on the concentration of the chemical elements - heavy metals in the studied zonal and azonal soil types was determined.
