Removal of pharmaceuticals from wastewater through constructed wetland-based systems in rural Canada
The main goal of the dissertation was to assess the occurrence and removal of pharmaceuticals in constructed wetlands (CWs) treating wastewaters under Arctic and temperate climates. To this end, we examined the relevance of observations and strength of methods found in the literature for the removal...

The main goal of the dissertation was to assess the occurrence and removal of pharmaceuticals in constructed wetlands (CWs) treating wastewaters under Arctic and temperate climates.
