Sažetak
Marine organisms have been recognized as a useful tool in monitoring of the environment because of their ability to accumulate chemical elements and compounds in tissues. Mussels have wide distribution on all continents and, therefore, they are commonly used as bio-indicators of changes in marine environment. Bioaccumulation of metals and lipophilic organic compounds through extraction from sea water can lead to accumulation of species in contents above those in the abiotic environment, which is most often confirmed by chemical analyses of mussel tissues [1, 2]. However, analysis of crude shell samples is very rarely applied, despite that it could provide additional information in understanding of bio-mineralization process. In this study, metal content was determined in powdered shell samples by inductively coupled plasma atomic emission spectrometry (ICP-AES). Samples of Mytilus galloprovincialis were collected along the Croatian Adriatic coast, in vicinity of populated area, where greater anthropogenic influence was expected. Analytical procedure included total digestion of powdered shell samples and reference material, following by measurement of the contents of selected elements i.e., Al, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, Sn, Sr and Zn. Results have shown that samples collected near harbors, city waste or sewage, and chemical industry centers indicate the certain level of contamination. It is shown that shell analysis provides useful data in determination of environmental status and also in estimation of possible anthropogenic influences.
