Population impacts in white sucker ( Catostomus commersonii) exposed to oil sands–derived contaminants in the Athabasca River
Abstract Biological and chemical endpoints were measured in white sucker collected downstream of Athabasca oil sands developments (AB, Canada) and compared with those at Calling Lake (AB, Canada), a reference location upstream of the Athabasca oil sands deposit. Naphthenic acid concentrations were a...
