Second‐round interlaboratory comparison of hepatic ethoxyresorufin‐O‐deethylase activity in white sucker (Catostomus commersoni) exposed to bleached‐kraft pulp mill effluent

Abstract Livers were collected from six male and six female white sucker (Catostomus commersoni) at both a bleached-kraft pulp mill effluent (BKME)-exposed site and a reference site during the 1992 spring spawning migration. A semistandardized methodology for 7-ethoxyresorufin-O-deethylase (EROD) analysis was proposed that featured similar physical and chemical conditions yet allowed for different instrumentation and techniques. …
