Definitions for "Total Kjeldahl Nitrogen"
There is no MCl for total kjeldahl nitrogen. This parameter is used to measure the total amount of organic nitrogen and is typically used for surface water and groundwater investigations associated with domestic or agricultural contamination.
The sum of organic nitrogen and ammonia in a water body. Measured in milligrams per liter (mg/L). High measurements of TKN typically results from sewage and manure discharges to water bodies.
Nitrogen in the form of organic proteins or their decomposition product ammonia, as measured by the Kjeldahl Method. The Total Kjeldahl Nitrogen (TKN) method involves digestion and distillation to determine both organically bound nitrogen and ammonia (NH3); an indicator of the nutrient enrichment of surface waters. Measured in mg/L or ppm.
