“…6. It is evident that acetaldehyde is the dominant source for PA formation with the contribution of 59.7% among the six carbonyls in Beijing, which was in agreement with the conclusion that acetaldehyde is often the dominant PA radical source over urban areas (Kondo et al, 2008;Roberts et al, 2001). The photolysis of acetone is the second largest contribution to the total PA radical with the production rate of ca.…”

a b s t r a c tPeroxyacetyl nitrate (PAN), a major secondary pollutant in the atmosphere, has received much concern for its particular importance in atmospheric chemistry and adverse effects on human and plants. Atmospheric PAN and PPN were measured by using a gas chromatograph equipped with electron capture detector (GC-ECD) from June to September 2010, and the source and major sink for PAN were firstly studied in Beijing. The distinct diurnal variations of PAN and PPN with maximum in the afternoon were observed, and the mean and maximum values were 2.61 ± 2.57 ppbv (N ¼ 839) and 12.5 ppbv for PAN and 0.52 ± 0.38 ppbv (N ¼ 152) and 2.16 ppbv for PPN during the measuring period, respectively. Good correlation (R ¼ 0.85) between PAN and PPN with a slope (DPPN/DPAN) of 0.134 indicated that anthropogenic volatile organic compounds (AVOCs) dominated the photochemical formation of PANs in Beijing. Further, we found acetaldehyde was the predominant carbonyl precursor of PAN with the contribution of 59.7% to the total peroxyacetyl (PA) radical. Methyl glyoxal, methacrolein, acetone, methyl vinyl ketone, and biacetyl contributed 7.1%, 8.8%, 19.7%, 3.4%, and 1.3% to total PA radical, respectively. Anti-correlation between PAN concentrations and the NO/NO 2 ratios was found during the whole investigating period. In addition, the amount of PAN lost by thermal decomposition (TPAN) accounted for remarkable fractions of PAN observed under high temperature during both daytime and nighttime.

“…The purpose of the simulation in and around Tokyo is to validate the VBS scheme over the region where meteorological fields, emissions, and the concentrations of precursor gaseous species are relatively well known (compared with over the Asian region). We used observed data during the Integrated Measurement Program for Aerosol and oxidant Chemistry in Tokyo (IMPACT) campaign (Takegawa et al, 2006a, b;Kondo et al, 2006Kondo et al, , 2007Kondo et al, , 2008Kondo et al, , 2010.

Volatility basis-set approach simulation of organic aerosol formation in East Asia: implications for anthropogenic–biogenic interaction and controllable amounts

Abstract. Organic aerosol (OA) simulations using the volatility basis-set approach were made for East Asia and its outflow region. Model simulations were evaluated through comparisons with OA measured by aerosol mass spectrometers in and around Tokyo (at Komaba and Kisai in summer 2003 and and over the outflow region in East Asia (at Fukue and Hedo in spring 2009). The simulations with aging processes of organic vapors reproduced the mass concentrations, temporal variations, and formation efficiencies of observed OA at all of the sites reasonably well. As OA mass was severely underestimated in the simulations without the aging processes, the oxidations of organic vapors are essential for reasonable OA simulations over East Asia. By considering the aging processes, simulated OA concentrations increased from 0.24 to 1.28 µg m −3 in the boundary layer over the whole of East Asia. OA formed from the interaction of anthropogenic and biogenic sources was also enhanced by the aging processes. The fraction of controllable OA was estimated to be 87 % of total OA over the whole of East Asia, which indicated that most of the OA in our simulations were formed anthropogenically (from controllable combustion sources). A large portion of biogenic secondary OA (78 % of biogenic secondary OA) was formed through the influence of anthropogenic sources. These fractions were higher than the fraction of anthropogenic emissions. An important reason for these higher controllable fractions was higher oxidant concentrations and the resulting faster oxidation rates of OA precursors by considering anthropogenic sources. Both the amounts (from 0.18 to 1.12 µg m −3 ) and the fraction (from 75 to 87 %) of controllable OA were increased by aging processes of organic vapors over East Asia.

This study applies the chemistry version of the Weather Research and Forecasting model (WRF-Chem) to examine impacts of three additional HONO sources, i.e., the reaction of photoexcited NO 2 (NO 2 * ) with water vapor (NO 2 * chemistry), the NO 2 heterogeneous reaction on aerosol surfaces and HONO emissions, on concentrations and deposition of individual NO y species over the Beijing-Tianjin-Hebei region (BTH) in summer and winter periods of 2007. The results show that the three additional HONO sources produce a 20%~40% (> 100%) increase in monthly-mean OH concentrations in many urban areas in August (February), leading to a 10%~40% (10%~100%) variation in monthly-mean concentrations of NO x , NO 3 − and PAN, a 5%~10% (10%~40%) increase in the total dry deposition of NO y , and an enhancement of 1.4 Gg N (1.5 Gg N) in the total of dry and wet deposition of NO y over this region in August (February). These results suggest that the additional HONO sources aggravate regional-scale acid deposition, emphasizing the importance of the additional HONO sources in the NO y budget.(Citation: Li, Y., J. An, M. Kajino, J. Li, and Y. Qu, 2015: Impacts of additional HONO sources on concentrations and deposition of NO y in the Beijing-Tianjin-Hebei region of China. SOLA, 11, 36−42,
