Application of Physicochemical Estimation Methods to Bioaccumulation from Contaminated Sediments. II. Steady-State from Single Time-Point Observations,
Abstract
In this investigation asiatic clams, Corbicula fluminea, and fathead minnows, Pimephales promelas, were simultaneously exposed to industrially contaminated river sediments. A simple kinetics model and physicochemical estimation methods were applied to bioaccumulation of PCB as total di- and total tri-chlorobiphenyls. Results show that residues measured after a short exposure period together with elimination rate constants (k subscript 2) estimated from octanol/water partition coefficients (K subscript ow) can be used to approximate steady-state nonequilibrium tissue concentrations (C subscripts ss). Furthermore, normalization of residue data on tissue lipid content made comparisons of bioaccumulation between these dissimilar species possible.
