TLDR
Air mass backward trajectory and potential source contribution function (PSCF) analyses implied that areas of central and northern China contributed significantly to the concentration and chemical compositions of PM2.5 in Shanghai during winter, suggesting the importance of secondary aerosol formation during the three pollution events.About:

Air pollution in China: Status and spatiotemporal variations
Congbo Song,Lin Wu,Yaochen Xie,Jianjun He,Xi Chen,Ting Wang,Yingchao Lin,Taosheng Jin,Anxu Wang,Yan Liu,Qili Dai,Baoshuang Liu,Yanan Wang,Hongjun Mao +13 more
TL;DR: Though the air quality has been improving recent years, PM2.5 pollution in wintertime is worsening, especially in the Northern China, and more scientific air quality index standards are needed.
Journal ArticleDOI
A review of current knowledge concerning PM 2. 5 chemical composition, aerosol optical properties and their relationships across China
TL;DR: In this paper, the authors reviewed and summarized existing field studies conducted after the year 2000 in terms of geographical, interannual and seasonal distributions of PM2.5 chemical composition and its impact on aerosol optical properties across China.
Journal ArticleDOI
Short-term and long-term exposures to fine particulate matter constituents and health: A systematic review and meta-analysis.
TL;DR: Black carbon and organic carbon are important detrimental components of PM2.5, while other constituents are probably hazardous to human health, however, more studies are needed to further confirm the results.
Journal ArticleDOI
The role of seasonality in the spread of COVID-19 pandemic.
TL;DR: In this article, the seasonal signals of the COVID-19 time series are extracted using the EEMD method, and a modified SARS-CoV-2 model incorporated with seasonal factors is introduced to quantify its impact on the current COVID19 pandemic.

Socioeconomic factors of PM2.5 concentrations in 152 Chinese cities: Decomposition analysis using LMDI
TL;DR: Wang et al. as mentioned in this paper identified the key impact factors of PM2.5 concentration in 152 Chinese cities in eastern, central, and western China by using Logarithmic Mean Divisia Index (LMDI) method.

TL;DR: The results suggest that, in addition to mitigating primary particulate emissions, reducing the emissions of secondary aerosol precursors from fossil fuel combustion and biomass burning is likely to be important for controlling China’s PM2.5 levels and for reducing the environmental, economic and health impacts resulting from particulate pollution.

Parameterization of surface resistances to gaseous dry deposition in regional-scale numerical models
TL;DR: In this article, the authors proposed a method for estimating the dry deposition velocities of atmospheric gases in the U.S. and surrounding areas and incorporated it into a revised computer code module for use in numerical models of atmospheric transport and deposition of pollutants over regional scales.
