TL;DR: In this paper, a spatiotemporal variation of PM1 (mass concentrations of particles with aerodynamic diameter 0.9) was observed in North Eastern China, North China Plain, coastal areas of Eastern China and Sichuan Basin while lower ratios (<0.7) were present in remote areas in North-Western and Northern China (e.g., Xinjiang, Tibet and Inner Mongolia).

TL;DR: In this article, the authors investigated indoor particle number and PM2.5 concentrations in a radio station surrounded by busy roads and found that the indoor particle numbers were governed by outdoor air, and significantly affected by the location of air intake and design of HVAC system.

TL;DR: This study proved that this novel method can indeed be applied easily and quickly to a large group of people, and quantified the RTD of children, thus providing an important input to the risk assessment for exposure to UFP.

TL;DR: In this paper, the authors investigated the impact of the HVAC filtration system and indoor particle sources on the relationship between indoor and outdoor airborne particle size and concentrations in an operating environment.

TL;DR: Particle number, particle mass and CO2 concentrations were measured on the kerb of a busy urban busway used entirely by a mix of diesel and CNG operated buses, and the results showed that the median particle mass emission from CNG buses was less than 9% of that from diesel buses as mentioned in this paper.
