“…In both studies the relationships are quiet weak and highlight the difficulty in assessing metal exposure routes using small data sets in which a few data points can strongly influence the strength and direction of any relationships. The studies by King et al (2005) observed that zinc bioaccumulation is generally well explained by the dissolved zinc concentrations. For manganese, the bioaccumulation observed in S1 was much greater than the S2 and S3 sediments, and neither the dissolved nor the particulate manganese concentrations provided a useful relationship with the observed manganese bioaccumulation.…”

“…A biokinetic model of copper bioaccumulation exists for the bivalve (King et al, 2005), and for sediment S2 (with the highest AE-copper concentrations) the exposure to particulate copper through ingestion of fine sediments while foraging for food would be predicted to be a major source of accumulated copper. In sediment S3 the AE-copper concentration was very low at the start, but higher and quite variable at the completion of the experiments (Table A5) and may also have contributed to the observed copper accumulation in the bivalves in this sediment ( Figure A6).…”

Environmental Pollution, 208 (Part B), 590-599. See next page for additional authorsThe impact of sediment bioturbation by secondary organisms on metal bioavailability, bioaccumulation and toxicity to target organisms in benthic bioassays: implications for sediment quality assessment AbstractBioturbation alters the properties of sediments and modifies contaminant bioavailability to benthic organisms. These naturally occurring disturbances are seldom considered during the assessment of sediment quality. We investigated how the presence (High bioturbation) and absence (Low bioturbation) of a strongly bioturbating amphipod within three different sediments influenced metal bioavailability, survival and bioaccumulation of metals to the bivalve Tellina deltoidalis. The concentrations of dissolved copper decreased and manganese increased with increased bioturbation. For copper a strong correlation was observed between increased bivalve survival (53-100%) and dissolved concentrations in the overlying water. Increased bioturbation intensity resulted in greater tissue concentrations for chromium and zinc in some test sediments. Overall, the results highlight the strong influence that the natural bioturbation activities from one organism may have on the risk contaminants pose to other organisms within the local environment. The characterisation of field-based exposure conditions concerning the biotic or abiotic resuspension of sediments and the rate of attenuation of released contaminants through dilution or readsorption may enable laboratorybased bioassay designs to be adapted to better match those of the assessed environment.  Strong correlations between bioaccumulated and dissolved Cd, Cr, Pb, Zn, Cu and Ni. Weak correlations between bioaccumulated and particulate metals. 2 Capsule AbstractThis study investigated the impact of sediment bioturbation intensity on metal bioavailability and toxicity to aquatic organisms, and the implications of this to toxicity test design.

. (2015). Metal fluxes from porewaters and labile sediment phases for predicting metal exposure and bioaccumulation in benthic invertebrates. Environmental Science and Technology (Washington), 49 (24), 14204-14212. Metal fluxes from porewaters and labile sediment phases for predicting metal exposure and bioaccumulation in benthic invertebrates AbstractThe use of diffusive gradients in thin films (DGT) for predicting metal bioavailability was investigated by exposing the bivalve Tellina deltoidalis to an identical series of metal-contaminated sediments deployed simultaneously in the field and laboratory. To understand the differences in metal exposure occurring between laboratory and field-based bioassays, changes in metal fluxes to DGT probes in sediments, and metal concentrations and partitioning to porewaters and overlying waters were investigated. DGT-metal fluxes (Cu, Pb and Zn) were lower in the overlying waters of most field-bioassays compared to the laboratory, causing differences in Pb and Zn bioaccumulation between bivalves exposed to laboratory and field conditions. Overall, DGT-metal fluxes provided predictions of metal bioaccumulation similar to those obtained using dilute-acid extractable metal measurements. This study demonstrates that, irrespective of the physicochemical properties of the sediment and type of exposure (laboratory or field), sediments pose a significant risk of bioaccumulation by T. deltoidalis when the Cu, Pb and Zn DGT flux exceeds 3.5, 1.3 and 156 µg/h/m2, respectively. The results presented here support the use of the DGT technique for sediment quality assessment and the hypothesis that DGT-metal fluxes may potentially be useful surrogates for the lability of metals for all exposure routes. * Corresponding author: Dianne JolleySchool of Chemistry, University of Wollongong, NSW 2522, Australia tel.: +61 2 4221 3516 E-mail address: djolley@uow.edu.au Rationale: Many sediment quality assessment frameworks consider the bioavailability of contaminants when evaluating the risk posed by contaminants to benthic communities. For metals, analyses of acidvolatile sulfide (AVS), simultaneously extracted metals (SEM) (dilute-acid extractable metals) and organic carbon (OC) are commonly used to assist in the bioavailability assessment. Although these approaches frequently provide useful information, they may result in inadequate predictions of risk of toxicity as they are based on a single measurement ('snapshots' temporally and spatially) that do not adequately reflect how the broader sediment properties (including particle size, iron and manganese oxyhydroxides etc) influence metal bioavailability. Diffusive gradients in thin films (DGT) is an in-situ technique which provides a timeintegrated measure of metal fluxes from the pore water and labile sediment phases, allowing the quantitative evaluation of the sediment metal 'release potential'. In this study, we assess the performance of the DGT technique to predict metal bioavailability by comparing DGT metal fluxes with metal bioaccumulati...

“…A key characteristic that makes the amphipod M. plumulosa an ideal sentinel species for monitoring and assessing sediment health is that it feeds on detritus by ingesting sediment, and is therefore directly exposed to sediment-bound toxicants and contaminants King et al, 2005;Spadaro et al, 2008). Studies have demonstrated this amphipod to be sensitive to both aqueous and sediment-bound metals and PAHs in both acute and chronic exposures, with juvenile animals displaying greater sensitivity than adult M. plumulosa Hyne et al, 2005;King et al, 2005Spadaro et al, 2008).…”
