Journal ArticleDOI
Mineral dust and NOx promote the conversion of SO2 to sulfate in heavy pollution days
Hong He,Yuesi Wang,Qingxin Ma,Jinzhu Ma,Biwu Chu,Dongsheng Ji,Guiqian Tang,Chang Liu,Hongxing Zhang,Jiming Hao +9 more
TL;DR: A new mechanism of haze formation is reported, in which coexistence with NOx can reduce the environmental capacity for SO2, leading to rapid conversion of SO2 to sulfate because NO2 and SO2 have a synergistic effect when they react on the surface of mineral dust.
Journal ArticleDOI
Contrasting trends of PM2.5 and surface-ozone concentrations in China from 2013 to 2017
Yonghong Wang,Yonghong Wang,Wenkang Gao,Shuai Wang,Tao Song,Zhengyu Gong,Dongsheng Ji,Lili Wang,Lili Wang,Zirui Liu,Guiqian Tang,Yanfeng Huo,Shili Tian,Jiayun Li,Mingge Li,Yuan Yang,Biwu Chu,Biwu Chu,Tuukka Petäjä,Veli-Matti Kerminen,Hong He,Jiming Hao,Markku Kulmala,Yuesi Wang,Yuanhang Zhang +24 more
TL;DR: It is demonstrated that the Chinese government was successful in the reduction of particulate matter in urban areas from 2013 to 2017, although the ozone concentration has increased significantly, suggesting a more complex mechanism of improving Chinese air quality in the future.
Journal ArticleDOI

TL;DR: Measurements in the CLOUD chamber at CERN show that the rapid condensation of ammonia and nitric acid vapours could be important for the formation and survival of new particles in wintertime urban conditions, contributing to urban smog.
Journal ArticleDOI
Atmospheric new particle formation in China
Biwu Chu,Veli-Matti Kerminen,F. Bianchi,F. Bianchi,Chao Yan,Tuukka Petäjä,Tuukka Petäjä,Markku Kulmala,Markku Kulmala +8 more
TL;DR: In this paper, the particle formation (NPF) studies in China were summarized comprehensively and compared among the observations carried out at different types of sites in different regions of China in different seasons, with the aim of exploring the nucleation and particle growth mechanisms.
Journal ArticleDOI
Significant concurrent decrease in PM 2.5 and NO 2 concentrations in China during COVID-19 epidemic
TL;DR: Wang et al. as mentioned in this paper analyzed the temporal variation and spatial distribution of air pollutant concentrations in China during COVID-19 epidemic and found that the decreases in PM2.5 and NO2 concentrations showed relatively consistent temporal variation.
