[Characteristics of Water-soluble Inorganic Ions in PM2.5 and PM2.5-10 in Mountain Background Region of East China in Spring].

PM2.5 and PM2.5-10 samples were collected during March to May of 2014 at the National atmospheric background monitoring station (Wuyishan station) in Fujian Province.

[Influence of atmospheric transport on air pollutant levels at a mountain background site of East China].

Transport characteristics of air pollutants transported to the background atmosphere of East China were investigated using HYSPLIT (Hybrid Single Particle Lagrangian Integrated Trajectory) 4.8 model driven by NCEP reanalysis data during June 2011 to May 2012. Based on the air pollutants monitoring data collected at the National atmospheric background monitoring station (Wuyishan station) in Fujian Province, characteristics of different clustered air masses as well as the origins of highly polluted air masses were further examined.
