Determination of the stability constants of dissolved iron(III) glycine system in water solution (I = 0.6 mol L in NaClO4, pH = 7.3 at 25±1 oC) using differential pulse cathodic voltammetry (DPCV) and cyclic voltammetry (CV) was performed out on a static mercury drop electrode (SMDE). By choosing voltammetry as analytical tool, measurements with lower(More)
Anthropogenic mercury pollution was studied in Kastela Bay (Croatia), 10 years after chloralkaline plant (PVC) stopped production. The concentration of total mercury determined in sediments which are composed mainly of calcite and quartz, are in the range 14,280-30,400 ng/g. The values are higher than reported in the literature for Elbe and Seine estuaries(More)
The applicability of the previously developed method for electrochemical determination of dissolved uranium concentration has been tested on natural water samples taken from the Krka river estuary during various seasons and along different depth profiles. The method is based on the following treatment of the sample: destroying the uranyl-carbonato complexes(More)
Copper accumulation was studied in native mussels, Mytilus galloprovincialis, Lmk., from the Limski Kanal, North West Yugoslavia (Peninsula Istria), from June 1979 to June 1980. The distribution of copper between different body parts of the mussels is correlated with the concentrations of the different physico-chemical forms of copper in the ambient(More)
Biometric features and physico-chemical conditions are responsible for many of the variables for metal concentrations in indigenous populations of mussels. In order to reduce variations and promote the utility of mussels as bioindicator organisms for environmental mercury concentration levels, individuals of approximately uniform biometric characteristics,(More)
Elemental analysis of prehistoric human bone for the reconstruction of past environmental conditions, diets and migrations is a relatively new concept and can be a helpful tool in palaeoanthropology. The contents of Pb, Cu, Cd, Zn, Ca, Sr and Ba in fossil and recent human bone were determined by inductively coupled plasma atomic emission spectrometry(More)
Fluxes of dissolved nutrients in the organic-rich sediment of Makirina Bay (Croatia) were estimated in in-situ incubation experiments and compared to those calculated from a diagenetic model based on the concentration vs. depth profiles in the pore water extracted from a sediment core at the same sampling site. Benthic fluxes observed in the in-situ(More)
