| 520 | |a"The role of nutrients in natural waters is very well known (Jenkins,1968). One such nutrient, nitrogen, occurs in natural waters in inorganic as well as organic forms. The differentiation of various forms of nitrogen is of considerable value in the study of some specific biological aspects of pollution (Jenkins, 1968) and, to further our understanding of this phenomenon, the Water Quality Division has undertaken to monitor the total nitrogen content and the concentration of various forms of nitrogen that might be present in natural waters"--p. 1. |
