“…Rather, our findings suggest that tissue- and species-specific physiology may more accurately explain Cd concentration patterns. Our study indicates that tissue type and the inclusion of lower trophic level biota are important for investigating food web processes, and caution is warranted when interpreting Cd biomagnification in marine biota over a narrow range in trophic position (Chevrollier et al 2022 ; Øverjordet et al 2015 ; Tian et al 2022 ).…”

We investigated trophic transfer of cadmium (Cd) through an Arctic marine food web in Hudson Bay and compared it with mercury (Hg), a metal known to strongly biomagnify. We evaluated blue mussel, sea urchin, common eider, sculpin, Arctic cod, and ringed seal for the influence of dietary and biological variables on variation in Cd and Hg concentrations. Age and size influenced metal concentrations among individuals within a vertebrate species. Consumer carbon and sulfur isotope values were correlated with their Cd and Hg concentrations, indicating habitat-specific feeding influenced metal bioaccumulation. Trophic transfer patterns for Cd depended on the vertebrate tissue, with food web biodilution observed for the muscle but not the liver. Liver Cd concentrations were higher in ringed seal and some common eider relative to prey. In contrast, we observed mercury biomagnification for both tissues. Tissue- and species-specific physiology can explain discrepancies of Cd trophic transfer in this Arctic marine food web.

“…The intake of metals in phytoplankton cells results from passive (diffusion and adsorption) and active uptake mechanisms (complexation of dissolved metals) and is driven by bioavailability conditioned by metal speciation and abundance [ 100 ]. Hg II and MeHg are present in the environment in different forms, which fundamentally affect their bioavailability and toxicity for microalgae [ 10 ].…”

The biogeochemical cycling of mercury in aquatic environments is a complex process driven by various factors, such as ambient temperature, seasonal variations, methylating bacteria activity, dissolved oxygen levels, and Hg interaction with dissolved organic matter (DOM). As a consequence, part of the Hg contamination from anthropogenic activity that was buried in sediments is reinserted into water columns mainly in highly toxic organic Hg forms (methylmercury, dimethylmercury, etc.). This is especially prominent in the coastal shallow waters of industrial regions worldwide. The main entrance point of these highly toxic Hg forms in the aquatic food web is the naturally occurring phytoplankton. Hg availability, intake, effect on population size, cell toxicity, eventual biotransformation, and intracellular stability in phytoplankton are of the greatest importance for human health, having in mind that such Hg incorporated inside the phytoplankton cells due to biomagnification effects eventually ends up in aquatic wildlife, fish, seafood, and in the human diet. This review summarizes recent findings on the topic of organic Hg form interaction with natural phytoplankton and offers new insight into the matter with possible directions of future research for the prevention of Hg biomagnification in the scope of climate change and global pollution increase scenarios.

“…Environmental pollutants of toxic heavy metals are present in high concentrations in the environment, such as Pb, Cd, Cr, Zn, Cu, Co, Fe, Ni, and As, contaminate the water, soil, fauna, and flora (Borgheipour et al, 2020). Plankton, situated at the base of food chains, can assimilate heavy metals and organic contaminants, which subsequently undergo biomagnification, resulting in substantial concentrations at higher trophic levels (Chevrollier et al, 2022). Heavy metals have the potential to be introduced into an organism's body either by direct exposure to the abiotic environment through absorption and inhalation from water, sediments, and soil or by consumption of contaminated food or prey, which accumulate in their tissues as a result (Liu et al, 2020).…”

Bioaccumulation and biomagnification of heavy metals occur constantly in the aquatic environment. Therefore, this study aimed to simulate the environment in the laboratory conditions and study the amount of lead (Pb) and cadmium (Cd) accumulation in two types of algae microalgae Dunaliella salina and Tetraselmis suecica. These algae were exposed to metals for a short duration of 21 days. After this period, they used these algae as food for Artemia salina (brine shrimp). The results showed that Pb was bio-accumulated in D. salina, between 12.65 and 1262 ppm, respectively, when exposed to a concentration of 50 and 1500 ppm., while the T. suecica was bio-accumulated Pb at a concentration of 20 and 1363 ppm when exposed to the same concentrations respectively. Also, Cd bio-accumulated in D. salina between 9.99 and 1148 ppm, while bioaccumulated Cd in T. suecica at a concentration of 10.71 and 1110.8 ppm, respectively, while when Artemia feed on algae (D. salina and T. suecica), that accumulated Pb and Cd after 21 days. The high biomagnification of Artemia for Pb (688.56 ppm) and the high bio-magnification of Artemia for Cd (700.99 ppm) when using D. salina as food. There are many environmental studies on the transfer of pollutants, especially heavy metals, in the food chain, but this study is one of the few studies that simulate the aquatic environment under controlled laboratory conditions for the accumulation of heavy metals in the food chain while minimizing the influence of interactions from other influences.
