Water Quality Guidelines for the Protection of Aquatic Life
Freshwater
Short Term Concentration (µg/L) No data
Long Term Concentration (µg/L) 19
Ammonia guideline: Expressed as μg un-ionized ammonia/L. This would be equivalent to 16 μg ammonia-N /L (=19*14.0067 / 17.031, rounded to two significant figures). Guideline for total ammonia is temperature and pH dependent, please consult factsheet for more information.
Consult the table on the total ammonia page for more information.
