Sažetak
The goals of this paper were to determine concentration of cadmium in agricultural soils on limestones in Dalmatia, Croatia and compare it with soil guideline values (SGV) set up in Croatian regulation on the protection of agricultural land (NN 9/14) and some EU countries. In a total, 22 topsoil samples (0-25 cm) were taken in the olive groves and vineyards located in the vicinity of city of Primošten and on the island of Brač and Šolta and analysed for pH, soil organic carbon (SOC) content, P2O5 and K2O, particle size distribution and Cd concentration. The cadmium was extracted with aqua regia and determined by inductively coupled plasma - optical emission spectrometry (ICP-OES). The Cd concentration ranged from 0.68 to 2.89 mg kg-1. The median value of 1.80 mg kg-1 was ten times greater than the median value of European agricultural soils established in GEMAS project. The maximum concentrations of Cd in soil samples of Primošten, Brač and Šolta were 2.27, 2.89 and 2.55 mg kg-1 respectively. In 9 of 22 soil samples (41%), the concentrations of the cadmium exceeded the maximum admissible concentration (MAC) value of 2.0 mg kg-1 given in mentioned Croatian regulation. Obtained anomalous Cd concentrations imply the need for establishing the origin of Cd in these soils, as well as spatial distribution of areas with elevated levels of Cd in soils.
