Atmospheric temperature inversions frequently trap pollutants in the urban atmospheres of Alberta leading to photochemical air pollution. Peroxyacetyl nitrate (PAN) was monitored, for the first time in Alberta, from November 1980 to August 1981 at the University of Calgary using electron capture gas chromatography. Measurements were made at one-half-hour intervals from July, 1981 to February, 1982 at a downtown location. Maximum PAN concentrations were recorded at the University and downtown sites on August 14 at 1400 h, 1981 and the values were 2.4 and 6.6 ppb, respectively. In each case the maximum PAN peak coincided with the afternoon peak in ozone concentrations, 79 ppb at the University and 59 ppb at the downtown site. Surprisingly, a high value of 2.3 ppb PAN was recorded at the University during January of 1981 giving rise to questions regarding the influence of low temperatures and solar radiation on the photochemical formation of PAN. Calculations employing a simple photochemical model for PAN and ozone formation have been carried out and comparisons made between the observed and the computed values.

“…This reactor is similar to the one used for the preparation of PAN which has recently been described. 9 Carbon filtered air containing measured concentration of propene and nitrogen dioxide was fed continuously into one leg of the reactor. With a flow rate of 2.3 liters per minute this gave a residence time of 61 minutes.…”

“…51 Air from a 2-mf stainless-steel sample loop is swept onto a teflon® G.C. column containing 5% Carbowax E400 on 100/120 mesh HMDS-treated Chromosorb W. Other electron capturing constituents of the air are 1 also detected, giving a chromatogram such as that shown in Figure 4 The system is calibrated using a standard atmosphere of PAN, produced in the laboratory by photolysis of ethyl nitrite in pure oxygen.…”
