<p>Secondary aerosols are a major component of PM<span class="inline-formula"><sub>2.5</sub></span>, yet their formation
mechanisms in the ambient atmosphere are still unclear. Based on field
measurements in downtown Beijing, we show that the photolysis of nitrous
acid (HONO) may promote the formation of organic and nitrate aerosols in
winter in Beijing, which is supported by the fact that the mass
concentrations of organic and nitrate aerosols linearly increase as a
function of HONO consumed from early morning to noon. The increased nitrate
content also leads to the formation of ammonium particulate matter through
enhancing the neutralization of nitrate and sulfate by ammonia. We further
illustrate that during pollution events in winter in Beijing, over 50 %
of the ambient HONO may be related to traffic-related emissions, including
direct emissions and formation via the reaction between OH and
vehicle-emitted NO. Overall, our results indicate that traffic-related HONO
may play an important role in the oxidative capacity and in turn contribute
to haze formation in winter in Beijing. The mitigation of HONO and NO<span class="inline-formula"><sub><i>x</i></sub></span>
emissions from vehicles may be an effective way to reduce the formation of
secondary aerosols and severe haze events in winter in Beijing.</p> |
