“…However, a potential cause of low Pb trophic transfer efficiency has not been well understood. Rainbow et al (2006a) have experimentally demonstrated that benthic invertebrate predators (Nereis virens and Palaemonetes varians) accumulated a considerably low amount of Pb from a deposit-feeding polychaete (Nereis diversicolor) col- lected from highly metal-polluted creeks in southwest England. The authors suggested that this low Pb trophic transfer efficiency may have been the result of its high affinity to insoluble granules (not part of TAM) in prey (Rainbow et al, 2006a).…”

Intracellular partitioning of trace metals is critical to metal tolerance in aquatic organisms and may also influence metal trophic transfer in ecosystems. In this study, we tested the relevance of metal (Cd, Cu, Pb, and Zn) intracellular partitioning in prey as an indicator of metal trophic availability to benthic forage fish, mummichogs (Fundulus heteroclitus), in chronically metal-polluted salt marshes in New York, USA. Two common prey of mummichogs in the study area, Palaemonetes pugio and Nereis acuminata, generally stored increasingly higher proportions of non-essential metals (particularly Pb) in insoluble (less trophically available) cellular components, as the whole body burdens increased. In contrast, intracellular partitioning of essential metals (Cu and Zn) in invertebrate prey varied relatively little among sites. Differential Cd and Pb intracellular partitioning patterns within P. pugio among sites were significantly associated with Cd and Pb whole body burdens in mummichogs, respectively (i.e., prey-driven bioreduction of metals), while bioaccumulation of Cu and Zn in mummichogs was similar among populations. The findings in this study suggest that metal intracellular partitioning within prey may be partially responsible for metal trophic availability to a predator in metal-polluted habitats, while there was also evidence that some predator-dependent processes may offset differential trophic availabilities from prey.

Biodynamic modelling has been used to predict bioaccumulated concentrations of Ag, Cd and Zn in the deposit-feeding polychaete Nereis diversicolor from 5 metal-contaminated estuaries in SW England and a relatively non-contaminated estuary in SE England. The modelling employed previously measured physiological parameters of bioaccumulation -uptake rate constant, assimilation efficiency (AE) and efflux rate constants after uptake from water and sediment ingestion -and measured sediment metal concentrations specific for each population. AEs were considered to relate to metals in the organic component of the ingested sediment and ingestion rates were therefore expressed in these terms, with the further assumption that the total sediment metal concentration is a proxy for the metal concentration in the sediment organic component. A range of growth rate constants was extracted from the literature, as were concentration ranges of dissolved Ag, Cd and Zn in contaminated coastal waters. The model showed that > 99% Cd and > 98% Zn accumulated by N. diversicolor is derived from sediment ingestion; more bioaccumulated Ag is derived from solution, the percentage contribution of the dissolved source increasing from 46 to 80% with an increase in Ag dissolved concentration from low to high values for coastal waters. Bioaccumulated metal concentrations predicted from the model generally showed excellent agreement with independently measured concentrations in field-collected worms, supporting the assumptions made in the model.

Fewer studies have addressed population differences and their implications for bioaccumulation, partly because such specific studies probably require determination of population-specific physiological parameters (e.g. Rainbow et al. 2009).Here we apply biodynamic modelling to compare bioaccumulation and the relative importance of water and sediment as sources of the trace metals Ag, Cd and Zn among 6 populations of the widespread infaunal estuarine polychaete Nereis diversicolor.

“…It is now appreciated that the uptake of trace metals from the diet is a significant route for their entry into marine animals (Wang 2002), with the further potential for the metals to be transferred along food chains (Wang 2002, 2006b. It is therefore relevant to identify general principles that govern the trophic bioavailability of trace metals (Wang & Fisher 1999).…”

The uptake of trace metals from the diet is a significant route for their entry into marine animals, and the chemical form of trace metals accumulated by food organisms is one potential factor controlling their assimilation from the diet. Therefore, we investigated relationships between the assimilation efficiencies (AE) of the trace metals Cd, Ag and Zn in the neogastropod mollusc Nassarius festivus and their subcellular compartmentalized fractionation in selected tissues of 4 species of bivalve prey, seeking to identify the relative trophic availabilities of such different fractions. We also sought parallels between the AE of N. festivus and 2 in vitro models of digestion, a generalised invertebrate model and a human digestion model. The bivalves were the scallop Chlamys nobilis, the clam Marcia hiantina, the green mussel Perna viridis and the oyster Saccostrea cucullata, as these show a range of accumulated trace metal concentrations and detoxificatory binding to subcellular compartments. Measured assimilation efficiencies of N. festivus for Cd, Ag and Zn from invertebrate prey tissues are very high in comparison to other marine animals, assimilation occurs from accumulated metal in prey bound in subcellular fractions across the insoluble and soluble spectrum, and assimilation is best modelled in vitro by a human digestion model with low pH (1.3) rather than an invertebrate model (pH 5.6). It is concluded that what is trophically available to one predator (feeding on one prey type) is not necessarily trophically available to another (taxonomically separated) predator even if feeding on the same prey, given the variability between invertebrate digestive systems. Variation in the subcellular distribution of accumulated trace metals within different prey will also add variation in trophic availability even for the same metal.
