Ambient levels of the peroxyacyl nitrates PAN, PPN, and MPAN in Atlanta, Georgia
- DGA, Inc., Ventura, CA (United States)
Ambient levels of the peroxyacyl nitrates [RC(O)OONO{sub 2}]PAN (R = CH{sub 3}), PPN (R = C{sub 2}H{sub 5}{minus}) and MPAN [R=CH{sub 2}=C(CH{sub 3}){minus}] have been measured in July - August 1992 in downtown Atlanta, Georgia. Ambient levels of PAN reached 2.9 ppb and averaged 0.71 {+-} 0.53 ppb (n = 817). PPN reached 0.37 ppb and averaged 0.14 {+-} 0.14 ppb (n = 119). Diurnal variations of PAN and PPN were similar and included nighttime minima and late afternoon/early evening maxima. MPAN was observed on only 12 occasions at levels averaging 0.32 {+-} 0.07 ppb. A brief descriptive analysis of the data is presented together with a documentation of our measurement and calibration protocols and the results of an interlaboratory comparison involving co-located measurements of ambient PAN. 43 refs., 5 figs., 4 tabs.
