As other areas on Montenegrin coast, Bokakotorska bay is also under a heavy impact of anthropogenic factors and the activities on the shore. The aim of the present work was to determine the levels of lead and cadmium in coastal surface sea water and sediment at three stations located in the inner shore waters Boka Kotor bay, and at one station located off shore Montenegrian coast considered as a reference station. The comparison of the results obtained for the inner shore stations with reference station showed that the content of this metals in some station are considerable increased in ratio to reference station.

A batch adsorption test was conducted to examine the adsorption characteristics of cadmium and copper on bed sediments of the Sava river and its relation to the concentration of dissolved metals. The adsorption of ions were studied using equilibrium technique as a function of adsorbate concentration. The adsorption data, over the whole range of concentrations used, follow the Langmuir adsorption isotherm. Cu2+ and Cd2+ adsorption isotherms were measured on some sediment samples obtained from 3 different sites.

The aim of this study was to determine the content of heavy metals, cadmium and lead, in drinking water, spring and well water from rural part of south Serbia, as in water of river Jablanica and in the top water. The content of cadmium and lead, a very toxic metals, were studied simulataneously by potentiometric stripping analysis (PSA) in water samples using thin mercury film electrode, as a working electrode, by standard addition method in the presence of supporting electrolyte. The results of content of examined heavy metals obtained in examined water samples by PSA method, are compared with results obtained by using AAS and GF-AAS spectrometry.
