Fast sulfate formation from oxidation of SO2 by NO2 and HONO observed in Beijing haze

Fast sulfate formation from oxidation of SO2 by NO2 and HONO observed in Beijing haze

How sulfur dioxide emitted through coal combustion is oxidized to sulfate particles during winter haze pollution events has been the subject of debate. Here, the authors show that rapid oxidation takes place by nitrogen dioxide and nitrous acid, producing nitrous oxide together with sulfate.
