Sažetak
Preliminary results on the application of the inducible metal binding protein, i.e. metallothionein (MT) as a biomarker for the assessment of metal exposure of indigenous mussels Mytilus galloprovincialis Lmk. are presented. This study is an amendment of the long-term monitoring program of the coastal seawater area by which the metal body-burden in edible bivalves has been monitored. An attempt is made to get the additional and relevant information on the biological response of the widespread, sessile and filter-feeding marine organisms, often used to monitor metal pollution of the marine and estuarine coastal areas. The objective of our study is to apply the reliable analytical and biochemical methods to determine toxic metals (cadmium, mercury) and the MT content in mussel tissues. The gills and the digestive gland are the mussel tissue involved in the process of metal uptake and detoxification and therefore related to the induction of MT. Under laboratory and field conditions, the induction of MT in the digestive gland and gills, as the consequence of bivalves exposure to cadmium and mercury respectively, is well documented. The intention of our study is therefore, to correlate the content of toxic metals with that of MT in gills and the digestive gland in order to assess the exposure of mussels and the biological effects of metal pollution.
