1
Freshwater data from Trussel (1972).
2
Seawater values from Bower and Bidwell (1978). Salinity for Seawater values = 34 ppt at
an ionic strength of 0.701 m.
FOR EXAMPLE:
A fresh water sample at 20°C has a pH of 8.5 and the test result is 1.0 ppm
as total Ammonia-Nitrogen.
1. The percentage from the table is 11.18% (or 0.1118).
2. 1 ppm total Ammonia-Nitrogen x 0.1118 = 0.1118 ppm Unionized
Ammonia-Nitrogen
3. Total Ammonia-Nitrogen
1.0000 ppm
Unionized Ammonia-Nitrogen
– 0.1118 ppm
Ionized Ammonia-Nitrogen
= 0.8882 ppm
