Abstract

In recent years, atmospheric chemists and air pollution researchers have increasingly looked beyond the “criteria” pollutants (i.e., those for which air quality standards have been established) such as ozone (O3), nitrogen dioxide (NO2), sulfur dioxide (SO2) and carbon monoxide (CO). Thus, interest has grown in the unambiguous identification and measurement of such species as nitric (HNO3) and nitrous (HONO) acids, formaldehyde (HCHO), the nitrate radical (NO3), the hydroxyl radical, etc. Of particular concern have been the trace nitrogenous species and the need to assess their roles in the chemical cycles of the clean and polluted troposphere, as well as their impacts on biological systems, including human health and vegetation. Recently, the emerging issue of nitrogenous “acid rain” has accelerated interest in these compounds.
