“…Elevated concentrations of metals in estuarine sediments and organisms are a well-documented environmental concern (Timothy, 2000;Klimmek and Stan, 2001;Blackmore and Wang, 2004;Podgurskaya et al, 2004;Cheung and Wang, 2005;Cravo and Bebianno, 2005;Falco et al, 2006;Feng et al, 2008). Although there are indications that Bohai Bay has become increasingly contaminated with metals in the past 20 years (Zhao and Kong, 2000;Zhang, 2001), the available data are restricted to localized inshore areas and lack spatial resolution.…”

“…However, it is known that the kidney of Gray's mussel can synthesize a greater amount of MTLP. Thus, in Gray's mussels inhabiting the effective area of powerful steady upwelling, these proteins that had an abnormally high concentration of Cd were isolated from the kidney [5]. Apparently, the synthesis of given proteins was quenched by the integrated effect of accumulated metals in Gray's mussel from heavy polluted Desantnaya Bay.…”

“…This process protects cellular structures from damage, as would happen in the organs of mussels from Desantnaya Bay ( Table 2). Such a pattern of prevailed binding of essential trace elements to the cytosol under an increased HM content in the environment was displayed in laboratory experiments on the gastropod Nassarius reticulatus [18] and in a study of C. grayanus from upwelling areas [5]. In contrast to Gray's mussel, in the northern horse mussel from the background area (st. 3), essential metals were bound to the cytosol.…”

Heavy metals (HM), when accumulated in the organism of hydrobionts, can cause disturbances in cellular metabolism. Cytotoxicity of metals is caused mainly by three interconnected mechanisms: increase of lipid peroxidation, suppression of mitochondrial respiration, and disturbance of cellular calcium homeostasis [1]. Bivalves have some patterns of regulation and fixation of the accumulated metals for damage protection of their intracellular structures and biochemical systems [12]. As a rule, the excess metals accumulate in the cytosol, where they form resistant complexes with specific low-molecular proteins (metallothioneins) of unique amino acid compositions and a high affinity for HM ions [17,23]. Hence, the subcellular distribution of metals indicates the efficiency of the process of translation of metals into nontoxic forms [27].Most of the studies concerning analysis of the subcellular distribution of heavy metals and their binding to cytoplasm proteins in bivalves has been carried out in toxic experiments [11,12,18,27]. However, the experimental conditions significantly differ from the natural conditions: the concentration of metals in water usually exceeded their content in nature, metals incoming with food were not taken into account, etc. Therefore, obtaining objective information requires field study of the subcellular distribution of metals in the tissues of mollusks living in natural conditions with a higher HM content in the ambient water [15]. Such works are still few, and almost none have been carried out in the Far East region. We stress also that such studies usually analyzed the soft tissues of mollusks in total [20,22], the digestive gland [21] or gills, and the digestive gland and residue tissues [13], not taking into account that the kidney, as the primary organ of metal excretion, is most exposed to the effect of accumulated toxicants.The objective of this work is a comparative analysis of the efficiency of the HM detoxication system in the mussels Crenomytilus grayanus (Dunker, 1853) and Modiolus modiolus (Linnaeus, 1758) (considered formerly as Modiolus kurilensis Bernard, 1983), continuously inhabiting a HM polluted biotope. MATERIAL AND METHODSThe related bivalve species, Crenomytilus grayanus and Modiolus modiolus, individuals of which were sampled from Desantnaya Bay (st. 1) in summer 2002, were studied (Fig. 1). This bay adjoins the area of the coast dump of industrial-residential wastes of the city of Vladivostok (Gornostai Bay). That is one of the most highly HM contaminated areas of Peter the Great Bay Abstract -The distribution of Zn, Fe, Ni, Cu, Mn, Cd, and Pb in subcellular fractions, and of Cd, Zn, and Cu in cytoplasm proteins of the kidney and digestive gland of the mussels Crenomytilus grayanus and Modiolus modiolus , sampled from contaminated and conditionally clean areas, was studied. It was found that, in a contaminated environment, the organs of mussels were more highly enriched with metals. It was shown that essential trace elements were accumulated mostly in the cytosol ...

“…The lower accumulation of these metals in soft tissue than in the shell could be due to the existence of metallothioneins that detoxify and store toxic metals (Podgurskaya et al 2004;Yap et al 2006;Cadena-Cárdenas et al 2009). Boening (1999) and Szefer et al (2002), reported that the bioavailability of Cd in soft tissue decreases with increasing salinity of the adjacent water.…”

The concentrations of Zn, Cd and Pb were determined in tissues (shell and soft tissue) of 144 of bivalve mollusks (Solen brevis) and 15 samples of surface sediment collected from three locations in intertidal zones of Bushehr coast, Persian Gulf, Iran in May 2011. The mean concentrations of Zn, Cd and Pb in the sediment samples were 26.2, 1.25, and 21.1 μg/g dw, respectively. The mean levels of Zn, Cd and Pb in the clam samples were 63.3, 0.67, and 4.38 μg/g dw in soft tissue and 10. 7, 1.53, and 15.6 μg/g dw in shell, respectively. The degrees of variability (CV %) for Cd and Pb within the shells were lower than for soft tissues, whereas the CV for Zn was lower in the soft tissue than in the shell, indicating that there is more precision (lower CV) in the determination of Cd and Pb in the shells and Zn in the soft tissues. Significant correlation were found between Cd (r = 0.63; p < 0.05) and Pb (r = 0.78; p < 0.01) concentrations in the shell of S. brevis and their concentrations in the surface sediments. Indeed, Zn concentrations in the soft tissue of S. brevis significantly (r = 0.63; p < 0.05) correlated with Zn concentrations in surface sediments. The results of this study suggest that the shell of S. brevis may serve as a reliable biomonitor for Cd and Pb, and the soft tissue for Zn.
