The particulate matter(PM)pollution has been significantly improved by carrying out various valid emission control strategies since 2013 in China.Meanwhile the variation trend of nitrous acid(HONO)is worthy to investigate due to its vital role in the atmospheric oxidation process.In this study,field observation in the winter is conducted to investigate the concentration of HONO in an urban area of Beijing.In the winter of 2019,the mean HONO concentration is 1.38 ppbV during the whole winter.Photo-enhanced NO_(2)heterogeneous reactions on the ground and aerosol surfaces were found as the possible daytime sources of HONO.Compared to O_(3),photolysis of HONO dominates the primary OH sources during the winter time.To understand the HONO pollution patterns by years variation,multi-year data is summarized and finds that primary pollutants including CO and NO decreased,but secondary pollutants i.e.,HONO(mostly generated via secondary process)increased.Our study highlights the requirement to mitigate secondary pollution by control HONO concentration.
