Short summary
As a result of strict emission control, nitrate-dominated PM2.5 in pollution episodes was observed in urban Beijing during the winter of 2017–2018. With the help of sufficient ammonia, particle pH could increase to near neutral (5.4) as particulate nitrate fraction increases. Further tests imply that airborne particle hygroscopicity would be enhanced at moderate RH in nitrate-dominated particles, and pH elevation will be accelerated when ammonia and particulate nitrate both increase.
As a result of strict emission control, nitrate-dominated PM2.5 in pollution episodes was...
