The exposure of the blue mussel Mytilus trossulus to increased concentration of cadmium in seawater resulted in the synthesis of a new protein of the approximate molecular weight of 60 kDa. This protein is immunologically crossreactive with the 60 kDa heat shock protein of the moth Heliothis virescens. The latter one is a member of a highly conserved family of proteins found in animals at various levels of organization. This result indicates that changes in the abundance of stress proteins may prove useful as a biomarket of mussels exposure to specific toxicants.

The accumulation of cadmium from food and seawater by the blue mussels Mytilus edulis was studied in laboratory conditions.Cadmium uptake from food was found to be just a tenth of that from seawater.The accumulation rate was rather strongly modified by cadmium concentration in seawater.At higher concentration, both, gills and hepatopancreas were the target organs for cadmium, whereas low concentration - cadmium was stored in hepatopancreas only.Considerable fraction of the accumulated cadmium was adsorbed on shell.A distinct difference in the kinetics of cadmium adsorption on shells food and seawater was noticed.

Contents of selected heavy metals (Al, Fe, Co, Ni, Cd, Pb, Zn, Cu, Cr) were meas-ured in sediment samples and biota collected off Spitsbergen. Relatively large contents of met-als in sediments were accompanied by small contents in mussels. This was attributed to the fact that sediments contain a significant amount of minerals rich in heavy metals of low bioavail-ability. Solid speciation revealed that metals incorporated into mineral lattice were by far more abundant than those adsorbed, bound to carbonates and hydroxides, and complexed to organic matter. This also explains scarce bioavailability of metals in the Spitsbergen region.
