Description:
The branchial elimination of pentachloroethane and four congeneric polychlorinated bephenyls by rainbow trout was measured using a fish respirometer-metabolism chamber and an adsorption resin column. Branchial elimination was characterized by calculating a set of apparent in vivo blood:water partition coefficients. Linear regression was performed on the logarithms of estimates and the log Kow value for each compared to give the fitted equation: - - - The linear nature of this relationship provides support for existing models of chemical flux at fish gills and suggest that a near equilibrium condition was established between chemical in venous blood entering the gills, including dissolved and found forms, and dissolved chemical in expired branchial water. - - -
