Survey of receiving‐water environmental impacts associated with discharges from pulp mills: 3. Polychlorinated dioxins and furans in muscle and liver of white sucker (Catostomus commersoni)

Abstract Polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) were measured in white sucker liver samples from seven pulp and paper mill sites, and three reference sites in Ontario. The mills included five bleached-kraft mills, with and without secondary treatment, and two sulfite-mechanical mills. 2,3,7,8-T4CDD and 2,3,7,8-T4CDF were the dominant congeners detected in both liver and fillet samples at all of the pulp and paper …
