TL;DR: Confidence is given to the regulatory bodies that even during unfavourable meteorology, a significant improvement in air quality could be expected if strict execution of air quality control plans is implemented.

TL;DR: In this article, the authors used the Community Multi-Scale Air Quality (CMAQ) model to estimate the changes of key air pollutants and found that during lockdown periods, significant reductions of PM 2.5 concentration and its major components were predicted, especially for secondary inorganic aerosols that are up to 92, 57, and 79% for nitrate (NO 3 - ), sulfate (SO 4 2 - ), and ammonium(NH 4 + ), respectively.

TL;DR: A review of the published literature on airborne microplastics can be found in this article , which gives an overview of the advantages and disadvantages of current airborne MPs collection techniques, extraction methods and identification (i.e., passive sampling, density separation and visual identification).

TL;DR: In this paper , current understandings on the physical and chemical characteristics, mixing state and heterogeneous chemical reactions of individual aerosol particles, mainly obtained with electron microscopes, are reviewed.

TL;DR: How the uncertainties in open burning emissions will influence PM2.5 simulation, on not only primary components but also secondary species is illustrated.
