SORPTION OF POTENTIALLY TOXIC METALS IN A FLUVISOL PROFILE AT THE PETRUŠEVEC SITE, (ZAGREB, CROATIA)

Contamination of soils with potentially toxic metals (PTMs) is an environmental problem. The subject of this study is a Fluvisol profile developed in the vicinity of the Petruševec wellfield area of the Zagreb aquifer, Croatia. The main objectives of the investigation were: 1) to determine the sorption characteristics of zinc, copper and cadmium using a batch experiment and 2) to build isotherms of PTMs in order to detect the potential impact of pollution on groundwater. Potential sources of contamination near the sampling area are industrial plants, traffic and intensive agriculture. Mathematical expressions were applied to establish the relationship between the concentration of the adsorbent in the liquid phase and the solid phase at equilibrium and in laboratory conditions. Relative sorption capacity was also used to compare the metal sorption capacity of the samples. Freundlich distribution coefficients were determined from sorption isotherms, and the sequence is Cu > Zn > Cd. The comparison of sorption isotherms has shown that copper has the strongest sorption in the soil. The topsoil (A horizon) has the maximum sorption capacity for all PTMs and varies between 26 and 50%. Sorption of PTMs generally decreases with depth. In the case of potential accidents and contamination with PTMs, it is evident that copper will be more bonded to soil particles in comparison to zinc and cadmium.
