Characterization and source apportionment of carbonaceous PM2.5 particles in China - A review
TL;DR: Li et al. as mentioned in this paper summarized recent studies on characteristics and sources of organic aerosols and assessed the current state of understanding of the organic aerosol pollution in China, concluding that OAs constitute ∼20-45% of the PM2.5 with an annual mean value of 5.2-44.5μg/m3 at sites across China.

Characterization and quantification of PM2.5 emissions and PAHs concentration in PM2.5 from the exhausts of diesel vehicles with various accumulated mileages.
TL;DR: Interestingly, with the increased high number of mileages ranged from 30,001 to 50,000 km, CO and NOx emission factor was observed to be declining, respectively, and could be attributed to the technological changes on new diesel vehicle models.
