Modeling bioconcentration of nonpolar organic pollutants by fish

Abstract: A model describing thermodynamically driven kinetic exchange of organic chemicals between fish and the aqueous environment is developed. This model considers both the biological attributes of the fish and the physicochemical properties of the chemical that determine diffusive exchange across gill membranes. Important biological characteristics addressed by the model are the fish's gill morphometry, body weight and fractional aqueous, lipid and structural organic composition. Relevant physicochemical properties… Show more

“…Barber et al then assumed that water flow through such lamellar channels could be treated as laminar slit flow [8,31,34]. Because the gill's secondary lamellae form flat channels having very high aspect ratios (i.e., mean lamellar height:interlamellar distance), the first of these assumptions was that water flow between adjacent secondary lamellae could be treated as water flow between parallel plates.…”

“…Extensive research into organic environmental micropollutants has enabled the elucidation of the mechanisms for the uptake and accumulation in biota (Barber et al., 1988, Barber et al., 1991, Mackay and Fraser, 2000). Uptake was mainly considered to occur by passive diffusion across cellular membranes and traditional models relied heavily on physico-chemical properties such as octanol-water partition coefficients (log P ) to describe and predict xenobiotic concentrations in biota (Kanazawa, 1981, Neely et al., 1974, Veith et al., 1979).…”

“…However, with some notable exceptions, the concepts have not been exploited, nor the data interpreted, to any great extent (Spacie & Hamelink, 1982;Mancini, 1983;Chew & Hamilton, 1985;Connolly, 1985;Barber et al, 1988). Bioconcentration bioassays on the other hand are fundamentally deterministic in nature; they focus on the kinetics of toxicant transfer between the environment and the exposed organism.…”
