TL;DR: In this paper, the impact of urbanization on air quality in the Yangtze River Delta (YRD) region was investigated and the authors found that urbanization exerted great impacts on the pollutant variations in urban agglomerations despite such large decreases in primary pollution.

TL;DR: In this paper, the formation mechanism and physicochemical characteristics of aerosols in different haze stages have been carried out, and the aerosol size distribution and chemical composition are found to have significant effects on its hygroscopicity, acidity/alkalinity and light extinction.

TL;DR: Based on the data of air pollutants in a typical regional haze pollution episode over North China Plain (NCP) in November 2018, Positive matrix factorization (PMF), potential source contribution function (PSCF) and concentration-weighted trajectory (CWT) models were used to analyze the sources and affecting areas of PM2.5 under different development stages as discussed by the authors.

TL;DR: In this article, the authors used a seven-channel aethalometer (AE-33) at the summit of Mt. Tai from May 11 to June 25, 2017.

TL;DR: In this article, the chemical compositions and mixing state of aerosols and their source apportionments during a regional haze pollution process in the North China Plain (NCP) were comparably discussed for the different haze evolution stages.
