英文摘要 | Hydroxyl (OH) radicals, nitrate (NO3) radicals and ozone (O-3) play central roles in the troposphere because they control the lifetimes of many trace gases that result from anthropogenic and biogenic origins. To estimate the air chemistry, the atmospheric reactivity and oxidation capacity were comprehensively analyzed based on a parameterization method at a suburban site in Xianghe in the North China Plain from 6 July 2018 to 6 August 2018. The total OH, NO3 and O-3 reactivities at the site varied from 9.2 to 69.6, 0.7 to 27.5 and 3.3 x 10(-4 )to 1.8 x 10(-2) s(-1) with campaign-averaged values of 27.5 +/- 9.7, 2.2 +/- 2.6 and 1.2 +/- 1.7 x 10(-3) s(-1) (+/- standard deviation), respectively. NOx (NO + NO2) was by far the main contributor to the reactivities of the three oxidants, with average values of 43 %-99 %. Alkenes dominated the OH, NO3 and O-3 reactivities towards total nonmethane volatile organic compounds (NMVOCs), accounting for 42.9 %, 77.8 % and 94.0 %, respectively. The total OH, NO3 and O-3 reactivi- ties displayed similar diurnal variations with the lowest values during the afternoon but the highest values during rush hours, and the diurnal profile of NOx appears to be the major driver for the diurnal profiles of the reactivities of the three oxidants. A box model (a model to Simulate the concentrations of Organic vapors, Sulfuric Acid and Aerosols; SOSAA) derived from a column chemical transport model was used to simulate OH and NO3 concentrations during the observation period. The calculated atmospheric oxidation capacity (AOC) reached 4.5 x 10(8) molecules cm(-3) s(-1), with a campaign-averaged value of 7.8 x 10 7 molecules cm(-3) s(-1) dominated by OH (7.7 x 10(7) molecules cm(-3) s(-1), 98.2 %), 0 3 (1.2 x 10(6) molecules cm(-3) s(-1), 1.5 %) and NO3 (1.8 x 10(5) molecules cm(-3) s(-1), 0.3 %). Overall, the integration of OH, NO3 and O-3 reactivities analysis could provide useful insights for NMVOC pollution control in the North China Plain. We suggest that further studies, especially direct observations of OH and NO3 radical concentrations and their reactivities, are required to better understand trace gas reactivity and AOC. |
