“…This, in turn, projected a lower time to steady state. The rates of elimination and time to steady state of PCBs in M. nasuta derived for the Arthur Kill sediment exposure more closely agree with those previously reported by Boese et al (1995Boese et al ( , 1997.…”

“…An additional study by Drouillard et al (2008) For N. virens, the 28-d and steady-state BSAFs were similar among congeners and between the Arthur Kill and Newark Bay sediment exposures ( Figure 16). The BSAFs obtained in this study were lower overall compared to previously reported values (0.19-1.41) (Pruell et al 1993 Ferraro et al 1990Ferraro et al , 1991Brannon et al 1993;Pruell et al 1993;Boese et al 1995Boese et al , 1996. Overall, the BSAFs obtained in this study for M. nasuta were lower compared to previously reported values.…”

“…A kinetic calculation was employed by inputting the TSS into Equation 1 as "t." In addition, an operational approach for estimating steady state was used; this method defines steady state as the mean tissue concentration between three consecutive and statistically indistinguishable time points (Boese et al 1995;ASTM 2000); this method can be used to estimate steady-state tissue residues in the absence of kinetic information. All statistical comparisons used the SigmaStat ® software package (SPSS, Chicago, IL).…”

“…For 2,3,7,8-TCDD, a factor of four has been suggested to adjust 28-d N. virens tissue residues to the steady-state concentration used in risk estimations while a factor of one (i.e., no correction) is used for the clam M. nasuta based on data from Pruell et al (1990). More recent work (e.g., Boese et al 1995Boese et al , 1996Boese et al , 1997 reports a longer time period required for M. nasuta to reach steady state, implying that a correction factor greater than 1 is warranted. This report presents evidence that these correction factors are not necessarily applicable.…”

“…Organisms were then thoroughly rinsed with DI water, blotted dry, weighed, and frozen at -80 C. Organism tissue from each replicate was composited and homogenized by pulverization using a mortar and pestle over liquid nitrogen until ground into a powder (Boese et al 1995). Pulverized tissue from each replicate was then weighed into separate scintillation vials for each chemical class and submitted for chemical analysis.…”

Determining Steady-state Tissue Residues for Invertebrates in Contaminated Sediment

Risk assessment of contaminated sediments often involves quantification of compounds in tissues via laboratory bioaccumulation exposures of benthic invertebrates. However, the standard 28-day exposure duration may not be adequately long for some compounds to reach steady state, defined as a stable concentration in exposed organisms. Steady-state tissue residues can be estimated using uptake and elimination rate constants. Experiments were conducted using two marine sediments from New York Harbor to assess bioaccumulation of PAHs, PCBs, chlorinated pesticides, dioxins, and Hg by sampling tissue during seven successive time points over an exposure of 56 days for the polychaete worm Nereis virens and 119 days for the clam Macoma nasuta. Exposure time required to attain steady state was organism and compound specific. Generally, N. virens tissues reached steady state more rapidly and accumulated higher contaminant residues. Nereis virens attained apparent steady state within roughly 28 days for PAHs, Hg, and most PCBs, but longer exposure was needed for some dioxins and pesticides. Steady state in M. nasuta was generally attained after 28 days of exposure for most compounds (some times after 100 days). Thus, some 28-day tissue residues may underestimate bioaccumulation and subsequently risk to benthos and higher trophic level organisms. The results of this study allow development of site-specific correction factors for estimating steady-state residues from 28-day exposures.

Interactions of polychlorinated biphenyls and organochlorine pesticides with sedimentary organic matter of retrogressive thaw slump‐affected lakes in the tundra uplands adjacent to the Mackenzie Delta, NT, Canada

et al. 2016

Using a comparative spatial analysis of sediment cores from eight lakes in tundra uplands adjacent to the Mackenzie Delta, NT, we examined how the presence of retrogressive thaw slumps on lake shores affected persistent organic pollutant (POPs, including polychlorinated biphenyls and organochlorine pesticides) accumulation in lake sediments. Sediments of slump‐affected lakes contained higher total organic carbon (TOC)‐normalized POP concentrations than nearby reference lakes that were unaffected by thaw slumps. Mean focus‐corrected inorganic sedimentation rates were positively related to TOC‐normalized contaminant concentrations, explaining 58–94% of the variation in POP concentrations in sediment, suggesting that reduced organic carbon in slump‐affected lake water results in higher concentrations of POPs on sedimentary organic matter. This explanation was corroborated by an inverse relationship between sedimentary POP concentrations and TOC content of the lake water. Inferred chlorophyll a, S2, and S3 carbon fluxes to sediment were not significantly correlated to POP fluxes. Higher POP concentrations observed in sediment of slump‐affected lakes are best explained by simple solvent switching processes of hydrophobic organic contaminants onto a smaller pool of available organic carbon when compared to neighboring lakes unaffected by thaw slump development.

ABSTRACT1. The purpose of this report is to determine the concentrations of tributyltin in sediments that would be protective against adverse effects on prey species of salmonids listed under the US Endangered Species Act.2. Two approaches for determining adverse sediment concentrations due to tributyltin (TBT) contamination are presented here. The first is the equilibrium partitioning (EqP) approach, which relies on a sediment-water partition coefficient and toxicological data for water exposures. The EqP approach utilizes the large water quality database that has been generated over the last two decades for TBT and provides strong evidence for adverse effects at low exposure concentrations.3. The second approach involves determination of a TBT tissue residue that is considered harmful for most species, which is then used to predict the sediment concentration that would likely produce this adverse tissue concentration.4. Both approaches are presented here because they generally support each other but based on the information presented below, and the inherent difficulty in measuring porewater concentrations, the tissue residue approach is the recommended method for determining adverse sediment concentrations.5. Using this analysis, the protective sediment concentration for TBT proposed here is 6000 ng g À1 organic carbon. Direct effects are not expected on salmonids at this sediment concentration because of their relatively short residence time in the estuary, general lack of interaction with sediment, and relatively high metabolic capacity. This concentration may ensure adequate abundance of salmonid prey species; however, it may not be low enough for the protection of sensitive benthic species.
