Studying dietary metal transfer kinetics is essential to gain a better understanding in global metal accumulation rates and its impacts in marine fish. While there exists a solid understanding on the influence of various biotic factors on this transfer, metal assimilation in fish might be also affected by abiotic factors, as has been observed in marine invertebrates. The present study therefore aims to understand the potential effects of two climate-related master variables, temperature and pH… 
The role of marine biotoxins on the trophic transfer of Mn and Zn in fish.
Overview of trace element trophic transfer in fish through the concept of assimilation efficiency
The need for further studies is noted, especially the influence of abiotic factors such as temperature, salinity or pH on trace element AE or in the context of the co-occurrence of multiple stressors, to better understand the trophic transfer of trace elements and thus their overall bioaccumulation in fish.
Functional significance and physiological regulation of essential trace metals in fish.
The physiological significance of iron, copper, zinc and manganese is summarized, the current state of knowledge on the mechanisms underlying transepithelial metal ion transport, metal-metal interactions, and cellular and systemic handling of these metals in fish are discussed, and knowledge gaps in the regulation of metal homeostasis are identified.
Application of nuclear techniques to environmental plastics research.


Influence of food on the assimilation of essential elements (Co, Mn, and Zn) by turbot (Scophthalmus maximus)
Results suggest that relationships between metal distribution in the prey and bioavailability to predator fish is not obvious as previously assumed based on marine organisms feeding on unicellular or simple pluricellular organisms.
Trophic transfer of (110m)Ag in the turbot Scophthalmus maximus through natural prey and compounded feed.
Effects of increased pCO2 and temperature on trace element (Ag, Cd and Zn) bioaccumulation in the eggs of the common cuttlefish, Sepia officinalis
The results suggest that pH and temperature affected both the permeability properties of the eggshell and embryonic metabolism, and the need to further evaluate the likely ecotoxicological impact of the global change on the early-life stages of the cuttlefish.
Assimilation and retention of metals in teleost and elasmobranch fishes following dietary exposure
TTF, calculated by dividing the product of metal AE and ingestion rate (IR) by ke, exceeded 1 only for Mn, Zn and Cs, suggesting that these metals will not biomagnify in piscivorous fishes.
Size‐dependence of the potential for metal biomagnification in early life stages of marine fish
Ingestion rate was the most important parameter accounting for the size-dependent bioaccumulation of metals, followed by dietary assimilation, and it was shown that the trophic transfer potentials of Se and Zn were > 1 in smaller fish but then reduced to < 1 in larger ones, suggesting that trophics are highly size dependent in marine fish.
Effects of ocean acidification on trace element accumulation in the early-life stages of squid Loligo vulgaris
The anthropogenic release of carbon dioxide (CO2) into the atmosphere leads to an increase in the CO2 partial pressure (pCO2) in the ocean, which may reach 950 !atm by the end of the 21st century.
