List of rate constants that were used for mass-balance analysis log K OW a Rate constant for Rate constant for chemical uptake via overall chemical the respiratory surface (k 1 ) b elimination (k 2 ) c L kg -1 d -1 d -1 Rate constant for chemical uptake via ingestion of suspended and bottom sediment (k sed ) d Average day 14 day 28 # # # #87/# # # # e.21 # #149/# e.17 #12/# # e.9 # e e e #164/# e.26 d -1 a Hawker and Connell (1988) b The rate constant k 1 was estimated using data from a bioconcentration study of the dioxin-like PCBs (tetra- to hepta-chlorinated, non-ortho-, and mono-ortho-substituted PCB congeners; the congeners had log Kow values of [Hawker and Connell, 1988]) in marbled sole (Fishery Agency, 23). We analyzed the data by using our own analysis of the reported data based on first-order kinetics. We used reliable k 1 values for congeners with K OW values ranging from 6.36 to 7.71; a good linear relationship was observed between k 1 and log K OW (see Fig. S1). c The rate constant k 2 was estimated using the empirical equation based on K OW (Equation 7) proposed by Hawker and Connell (1988). d For each congeners, we used the average, minimum, and maximum k sed values that were obtained at days 14 and 28. e The rate constant k 2 could not be calculated for #13, #149/#139, #128, #138, and #164/#163 because their C F-W values were greater than their C F values.

The reference rate constant k 1 was obtained by our own analysis of the data from a bioconcentration study of the dioxin-like PCBs (tetra- to hepta-chlorinated, non-ortho- and mono-ortho-substituted PCB congeners; the congeners had log Kow values of [Hawker and Connell, 1988]) in marbled sole (Fishery Agency, 23). Based on these reference k 1, we established a regression equation between k 1 and log K OW (k 1 = 418 log K OW ). We calculated the k 1 values that were used in the mass-balance analysis by using this regression equation.
