Biodynamic Modeling The simplified differential equation and its solution in closed form of the biodynamic model are described by dCorg dt
= k s ⋅ Cs + k w ⋅ Cw − ke ⋅ Corg (t )
(Eq. 1)
(k s ⋅ Cs + k w ⋅ Cw ) ⋅ (1 − e − ke ⋅t ) ke
(Eq. 2)
Corg (t ) =
The change of chemical tissue concentration in the organism is described by the sum of uptake from solids and water minus elimination processes. Contaminant uptake from water is described by an aqueous uptake rate constant, kw (L g-1 d-1), and the water contaminant concentration, Cw (μg/L). For filter feeders, Cw refers to the surficial water concentration and kw is further defined as the product of filtration rate (FR, L g-1 d-1), and aqueous assimilation efficiency (AEaq). The assimilation efficiency describes the fraction of contaminant that is assimilated into the organism (e.g., through the skin or gut wall) relative to the contaminant concentration to which the organism was exposed. For deposit feeders that do not filter water, the aqueous uptake rate, kw, describes the passive assimilation of contaminants through the water by dermal exposure and Cw can either be the surficial water, the pore water or a combination (e.g. when worms pump water through subsurface borrows for oxygenation). The contaminant uptake from sediment, ks, is described by the product of the organism’s ingestion rate or particle uptake rate (IR, g g-1 d-1), the contaminant sediment concentration Cs (μg g-1 dw), and the organism’s contaminant assimilation efficiency from ingested solids (AEs). The assimilation efficiency can vary greatly among organisms because it is dependent upon the digestive chemistry in the gut (e.g. (Ahrens, Hertz et al. 2001; Arnot and Gobas 2004) and references herein). Assimilation of pollutants through the aqueous phase is often dominated by the uptake of particulates with the water (Burton and Johnston 2010). Activated carbon amendments reduce (a) the aqueous concentration (Cw), and (b) reduce the assimilation efficiency from the solids (AEs) because the availability is much lower from AC than from native sediment. The value of AEs has to be modified for amended sediment accordingly:
S2
AEs
amended
= Fsed ⋅ AEssed + (1 − Fsed ) ⋅ AEsAC
(Eq. 3)
with AEsamended being the assimilation efficiency from the AC amended sediment, Fsed being the fraction of chemicals that remains on the sediment, AEssed being the assimilation efficiency from untreated sediment and AEsAC being the assimilation efficiency from AC. The value for Fsed can be estimated from the ratio of water concentration from well mixed slurries at quasi steady state with and without AC present. Fsed
CwAC = noAC Cw
(Eq. 4)
with CwAC and CwnoAC being the water concentrations before and after AC addition, assuming linear partitioning at low aqueous concentrations. Pathways that account for loss of contaminants from the organism’s tissue have to be subtracted from those uptake terms (Eq. 1 and 2). Loss can occur by elimination, described by the exponential rate constant ke (g g-1 d-1), when pollutants un-assimilated in the gut or gills are excreted. Exponential growth rates can be added to the loss term accounting for growth dilution (pseudo elimination). Similarly, other loss mechanisms can be included, e.g., biotransformation, however, in the case of polychlorinated biphenyls and the species employed for the modeling below, transformation can be neglected.
