摘要：

The paper describes briefly the analytical techniques used in measuring delta **1**5N, the main features of the isotopic cycle of nitrogen and the results obtained so far. A simplified model of the nitrogen cycle and its isotopic implications is presented; with this model one can deduce from a number of observed variations the physical or biological mechanism (or mechanisms) involved. Isotopic studies of nitrogen may be a useful additional tool for detecting and interpreting certain forms of pollution.
