Sub-lethal effects of oil sands process-affected water (OSPW) in two aquatic organisms : Daphnia magna and rainbow trout
My thesis contributes to a better understanding of the impacts of OSPW on aquatic organisms by investigating its sub-lethal effects on an invertebrate (Daphnia magna) and a vertebrate (rainbow trout) model species. Studies conducted on D. magna demonstrated that OSPW impairs feeding, reduces hemoglo...
