PM2.

Researcher Zhang Lin from the Department of Atmospheric and Oceanic Sciences, School of Physics, Peking University, researcher Gu Baojing from Zhejiang University, and Professor Mark Sutton from the British Eco-Hydrology Center, etc.

The joint research team used multiple global three-dimensional atmospheric chemistry numerical models (EMEP-WRF, TM5-FASST, GEOS-Chem) to quantify the contribution rate of nitrogen emissions from different countries and regions around the world to PM2.

Figure 1 Percentage of contribution of nitrogen emissions to global PM2.

The joint research team used the years of life lost (YLL) indicator to assess the impact of PM2.
