Spatial and temporal distribution of microplastics in the Ottawa River, Canada.
My proposed PhD research will sample the water and sediment at numerous selected locations throughout the Ottawa River watershed. Important point sources of microplastics to river ecosystems will be established, such as wastewater treatment plants, stormwater outfalls and where tributaries enter the Ottawa River. Once important point sources are established, sampling will be conducted through each season to determine any temporal variation in microplastic concentration in the river. Moreover, a currently established citizen science collaboration will enhance the spatial coverage of the research whereby volunteers will sample for microplastics over a 600 kilometer stretch of the Ottawa Valley and submit results for the current research.
