Priority Substances List Assessment Report, Ammonia in the Aquatic Environment (Environment Canada & Health Canada, February 2001)
This Priority Substances List Assessment Report evaluates whether ammonia in the aquatic environment meets the definition of 'toxic' under the Canadian Environmental Protection Act, 1999. The report concludes that ammonia is entering the aquatic environment in quantities and concentrations that have or may have harmful effects on aquatic ecosystems, particularly through chronic toxicity to sensitive fish species and benthic invertebrates from municipal wastewater discharges.
