Abstract	Cadmium (Cd) accumulation and subcellular distribution in the digestive gland and kidney of mussel Crenomytilus grayanus from naturally Cd elevated areas was studied. Mussels were collected from three sites of Okhotsk Sea and Sea of Japan: control area (site 1), seasonal upwelling region (site 2), and stationary upwelling region (site 3). Mussel from site 3 was shown to accumulate a significantly increased Cd concentration in the digestive gland and an extremely high Cd concentration (1780 ± 732 μg g−1 dry weight) in the kidney. Cd was mainly sequestered into the kidney cytosol of the mussels from both upwelling regions and control sites (73% to 96%). However, digestive gland cytosol bound about 55% of Cd for the mussels from sites 1 and 2 and only 22.4% of Cd for the mussel from site 3. In the organs of the mussels from upwelling regions, the most of cytosolic Cd was associated with the protein fraction corresponding to molluscan metallothioneins. MTLP was isolated from kidney cytosol of the mussels from site 3 (powerful upwelling regions) by gel filtration chromatography, whereas in the organs studied of the mussels from other sites, MTLP content was below the detection limit.
