    Abstract:

    Based on the online measurements from December 25,2017 to January 16,2018,we investigated the chemical composition and sources of PM2.5 in Yangjiang,a South China coastal city.PM2.5 in Yangjiang mainly consisted of OM,NO-3,SO2-4,NH+4 and EC,with proportions of 32.75%,25.59%,16.41%,12.37% and 4.82% in mass fraction,respectively.In two pollution events,the mass concentration of NO-3 increased to over 6 times of that during clean period,much higher than the increments of other components.The mass fractions of NO-3 in two polluted events increased to 29.38% and 30.81%,over twice of that in clean period.Source apportionment of PM2.5 were performed by Positive Matrix Factorization,which pointed out that secondary formation was the main source/process (51.41%) for PM2.5 in winter in Yangjiang.The secondary formation from NOx,contributing 27.18% to the total PM2.5 mass concentration,was the dominating secondary source.Vehicle exhausts were the biggest primary source (15.11%).In the pollution events,the contribution of the secondary formation from NOx sharply increased from 11.85% to 33.15% and 36.96%,which should be considered as the dominating source of PM2.5 pollution in winter of Yangjiang.This study revealed that,as a coastal city,Yangjiang exhibited similar characteristics to those big cities and mega-cities in terms of the PM2.5 sources,i.e.,dominated by the secondary formation.It suggested that more effort for pollution control should be put into the reduction of nitrates as well as their precursor NOx,meanwhile a persistent control of vehicles in Yangjiang city is recommended.
