“…A linear regression (p = 0.0016) was revealed between the Mn/Fe ratio in the U. pictorum and U. tumidus shells and in sediments from the corresponding biotopes in the Severnaya Dvina River Basin (Figure 8). Given that Mn/Fe ratio can serve as an indicator of the redox conditions at the sediment-water interface, i.e., [10], the accumulation of Mn relative to Ca in skeletons of mollusks reflects the corresponding redox conditions, which are operating under anoxic/suboxic conditions at the sediment-water interface. On the one hand, among various mechanisms, Mn, and Fe immobilization in the form of MnS and FeS both in the sediments and shells can be involved.…”

“…Zhao et al [10] suggested the ranking of different species of freshwater mollusks with respect to the Mn/Ca ratio in watercourses of different trophic status. In terms of their average Mn/Ca (mmol/mol) values in shells, the U. tumidus, U. pictorum and A. anatina samples from the studied basins (the Severnaya Dvina and the Onega rivers) correspond to mesotrophic watercourses (Figure 9).…”

“…Measuring TE concentration in shells of mollusks helps to track changes of different parameters in watercourses during long-time periods and to reveal local and global environmental impacts on riverine habitats [6]. For example, Zhao et al [10] found that patterns of the Mn/Ca index in the shells of Hyriopsis cumingii (Lea, 1852) are associated with the occurrence of reduction conditions at the bottom sediments water interface. Therefore, the use of the Mn/Ca ratio can potentially serve as a high-resolution marker of Mn mobility in the anoxic layer.…”

Trace elements in freshwater bivalve shells are widely used for reconstructing long-term changes in the riverine environments. However, Northern Eurasian regions, notably the European Russian North, susceptible to strong environmental impact via both local pollution and climate warming, are poorly studied. This work reports new data on trace elements accumulation by widespread species of freshwater mussels Unio spp. and Anodonta anatina in the Severnaya Dvina and the Onega River Basin, the two largest subarctic river basins in the Northeastern Europe. We revealed that iron and phosphorous accumulation in Unio spp. and Anodonta anatina shells have a strong relationship with a distance from the mouth of the studied river (the Severnaya Dvina). Based on multiparametric statistics comprising chemical composition of shells, water, and sediments, we demonstrated that the accumulation of elements in the shell depends on the environment of the biotope. Differences in the elemental composition of shells between different taxa are associated with ecological preferences of certain species to the substrate. The results set new constraints for the use of freshwater mussels’ shells for monitoring riverine environments and performing paleo-reconstructions.

“…The filter-feeding activity of H. cumingii may potentially support submerged macrophyte growth by reducing cyanobacterial density, but bivalve communities in natural water are in decline as a result of overharvesting [20]. Moreover, H. cumingii can also be used as a superior material for retrospective monitoring of eutrophication-induced environmental changes in aquatic ecosystems [21].…”

Hyriopsis cumingii plays an important role in aquatic ecosystems and fishery economy due to its potential value for water purification and edibleness. The present study was undertaken to reveal the short- and long-term purifying effects of H. cumingii on pond water. The short-term experiment results showed that total suspended solids, particulate organic carbon, and fatty acid in water were significantly eliminated by H. cumingii, with average percentage of filtering effect respectively reaching 22.19%, 57.48%, and 21.00% in the high-density group. Analogously, H. cumingii could significantly reduce phytoplankton biomass, species number, density, and chlorophyll-a concentration, especially in the control of diatoms, green algae, and cyanobacteria. Besides, electric conductivity also was significantly reduced by H. cumingii and its variation tendency showed a typical density-dependent effect. Similar purification effects were observed in chemical oxygen demand (COD), total nitrogen, and total phosphorus. In the long-term monitoring test, H. cumingii has also shown positive effects on the water transparency and the control to phytoplankton and COD in recirculating aquaculture pond. Overall, H. cumingii showed excellent ecological function, and the mixed breeding density of shellfish in the recirculating aquaculture pond is worth further exploration.
