TL;DR: In this article, in situ measurements of ROx radical precursors and products were carried out in four Chinese megacities (Beijing, Shanghai, Guangzhou, and Chongqing) during photochemically polluted seasons.

TL;DR: Wang et al. as discussed by the authors presented 3-year on-line measurements of PM2.5 chemical components from January 2011 to December 2013 at an urban site in Shanghai of YRD region.

TL;DR: PM2.5 constituents from the combustion of fossil fuel (e.g., OC and EC) may have an appreciable influence on the health impact attributable to PM2.

TL;DR: Wang et al. as discussed by the authors measured the seasonal contribution of secondary organic carbon (SOC) in Shanghai, and the results from the different methods were compared and evaluated, and it was found that SOC estimated with the tracer-based method accounted for only a small part of the SOC from the WSOCbased method, especially for the winter and spring sampling periods.

TL;DR: In this article, the authors investigated the factors that influence NAC formation (e.g., NO2, VOC precursors, RH and photolysis) through quantification of eight NACs, along with major components in fine particulate matter, selected volatile organic compounds, and gases.
