Abstract: Concentrations of hydrocarbons, carbon monoxide, carbon dioxide, condensation nuclei and nitric oxide were monitored near Fairbanks, Alaska, at a selected location not under the direct influence of a local pollution source. The measurements were made continuously over a period of weeks during January and February 1973, the period when atmospheric pollution would be expected to be most severe. Accumulation and dissipation of the pollutants was found to be related to atmospheric inversion conditions, wind speed and daily traffic patterns. Maximum hourly average concentrations of hydrocarbons, carbon monoxide, carbon dioxide and condensation nuclei were 9.7 ppm, 22.1 pp, 482 ppm and more than 10^4 N/cm^3 respectively. Comparative background levels are reported to be 1.4 ppm, 0.1 ppm, 320 ppm and 100-400 N/cm^3. Vehicle emissions appeared to be the primary source of the various pollutants.
