Note: Measurements of total ammonia in the aquatic environment are often expressed as mg/L total ammonia-N. The present guideline values (mg/L NH3) can be converted to mg/L total ammonia-N by multiplying the corresponding guideline value by 0.8224. Values falling outside of shaded area should be used with caution. Consult the factsheet for more details. No recommended guideline for marine waters.
