	abstract = {Reclaimed land in the Alberta oil sands mining area contains both reference and oil sands process-affected wetlands constructed using varying sediment compositions. The sediments derived from oil sands process materials (OSPM) may alter the biochemical reactions that take place and affect the sediment oxygen demand (SOD), which is a key factor that contributes to oxygen depletion. This presentation reported on a study in which SOD was measured in a suite of constructed wetlands of different ages, with or without OSPM and topsoil. The purpose of the study was to clarify the role of SOD in wetland function and in the reclamation process. Dissolved oxygen loggers were inserted into dome-shaped chambers on the sediment to measure changes in oxygen demand. Complementary measurements of respiration (CO2 elution) were used to quantify the biological sediment oxygen demand (BSOD) component of SOD. The chemical sediment oxygen demand (CSOD) was then determined by subtraction from SOD. Wetlands reclaimed using OSPM are expected to have a lower BSOD to CSOD ratio than reference wetlands. Residual ammonia in OSPM sediments may react with sulphate and bind phosphorus. This reduces phosphorus bioavailability and may impede submergent macrophyte growth. As such, wetlands affected by CSOD will have fewer submerged macrophytes than BSOD dominant wetlands.},
