Dear Khushhal,
EU standards are more recent (1998), more comprehensive and stricter than WHO (1993).

Dear Khushhal,
Ammoniacal nitrogen (NH3-N), is a measure for the amount of ammonia.
Permissible limit for drinking uses
WHO: No guideline value (already mentioned by Prof. Achour)
BIS (IS 10500 : 2012): 0.5 mg/L (max.) No relaxation.
Best wishes
As mentioned by other experts there are no WHO guideline line values for ammonia. In the 1993 Guidelines, no health-based guideline value was recommended,
but the Guidelines stated that ammonia could cause taste and odour
problems at concentrations above 35 and 1.5 mg/litre, respectively. pls see attached doc pg. 303.
Best regards,
Dr.Hina,
"Guidelines stated that ammonia could cause taste and odour problems at concentrations above 35 and 1.5 mg/litre, respectively". Yes it is correct; though there is no guideline value but an indication has been provided regarding taste and order problems at the said concentration levels.
Read the latest WHO Standard (2011), p.223.
"The threshold odour concentration of ammonia at alkaline pH is approximately 1.5 mg/l, and a taste threshold of 35 mg/l has been proposed for the ammonium cation.Ammonia is not of direct relevance to health at these levels, and no health-based guideline value has been proposed".
Regards
Dr. Asit iff you have soft copy of this recomendtion plz mail me at [email protected]. because am unable to find stnd . values of ammonical nitrogen.
Thank you
