NITRIC ACID IN THE ATMOSPHERE OVER BEIJING AREA

Sun Qingrui, Wang Meirong, Shao Kesheng Bai Yuhua, Dong Guoqiang, Huang Teng (Dept. of Technical Physics, Peking University)  
The concentrations of HNO3, NO2, O3, and NH3 in 173 samples collected during 1984, 12-1986,7 were determined and the data were then analyzed using multiple regression method. The results indicated that HNO3 concentration is significantly correlated to O3 concentration. In addition, HNO3 concentration increases with the increases in temperature and O3 concentration and decreases with the increases in relative humidity and NH3 concentration. Under low relative humidity condition, HNO3 (g) and NH3 (g) reach equilibrium with NH4NO3 (s) in the atmosphere.
