| Definition | Concentration of total nitrogen as determined using the Kjeldahl method for the determination of nitrogen in organic substances plus the nitrogen in inorganic ammonia and ammonium (NH3/NH4+) dissolved in a unit volume of water. The method of separation between dissolved and particulate material is either not known or is documented elsewhere. | ||
