TLDR
Analysis of the trophic transfer potentials of trace elements for which data are available in zooplankton, bivalves, and fish, suggests that slight variations in assimilation efficiency or elimination rate constant may determine whether or not some trace elements are biomagnified.About:

Why Is Metal Bioaccumulation So Variable? Biodynamics as a Unifying Concept
TL;DR: It is suggested that a biologically based conceptualization, the biodynamic model, provides the necessary unification for a key aspect in risk: metal bioaccumulation (internal exposure).

TL;DR: The findings suggest that: (1) the passive uptake of meHg does not control bioaccumulation at the base of aquatic food webs in nature (i.e. phyto- and bacterioplankton); (2) correlation with pH and DOC largely reflect the supply and bioavailability of me Hg to lower trophic levels; and (3) meHG concentrations at higher trophIC levels reflect uptake at low trophics and other factors, such

Framework for metals risk assessment.
TL;DR: The Framework for Metals Risk Assessment is a science-based document that describes basic principles that address the special attributes and behaviors of metals and metal compounds to be considered when assessing their human health and ecological risks.

Interactions of trace metals and different marine food chains
TL;DR: In this paper, food chain transfer in different marine food chains (plank- tonic and benthic) is reviewed, and any potential biomagnification of metals is predicted using the simple kinetic equation.

Biomagnification in marine systems: the perspective of an ecologist
TL;DR: Suggestions are made as to how data can be collected to better interpret the process of biomagnification in marine food webs.

Metal speciation and bioavailability in aquatic systems

TL;DR: In this paper, the Free-Ion Activity Model (FIAM) was used to model the relationship between trace metals and aquatic organisms, and the results showed that metal toxicity in aquatic organisms can be predicted from bioassays.

TL;DR: In the last decade, a new pattern of Hg pollution has been discerned, mostly in Scandinavia and North America, mostly due to more widespread air pollution and long-range transport of pollutants.

Metallothioneins in metal regulation and toxicity in aquatic animals
TL;DR: MT induction or increased levels of MT-bound metals in individuals in metal-contaminated environments can be used to justify continued development and testing of diagnostics markers of metal exposure based on MT function.
