| Abstract |
Samples of water from the Niagara, Genesee, Oswego and Black Rivers were collected from March to June 1973. The samples were analyzed for nitrogen forms and were incubated in darkness under aerobic conditions to promote mineralization of soluble inorganic nitrogen from the organic nitrogen in the samples. The amounts of ammonia and nitrate were determined as a function of the time of incubation. Generally over 50 percent of total nitrogen present in these river samples was immediately available for algal growth or potentially available after mineralization by bacteria. The results were highly variable from each tributary, and no single value could be selected from the data obtained to describe the availability of total nitrogen in a given river. |
