The release of wastewater contaminants in the Arctic: A case study from Cambridge Bay, Nunavut, Canada
Artículo The treatment of municipal wastewater in the Arctic is challenging due to a variety of financial, operational, climatic and technical issues. To better understand the efficacy of current wastewater treatment in this region and the hazard posed to receiving waters, we assessed the occurrence...
