Paper Title:
Size Distribution and Elemental Characteristics of Atmospheric Particles during Winter in Harbin
  Abstract

In order to investigate the characteristic of atmospheric particles, TSP, PM10 and PM2.5 were collected in winter and non-winter. This study investigates the size distribution and elemental characteristics of atmospheric particles. The results show that PM2.5 makes a great contribution to TSP, which changes with the concentration of TSP. PM2.5/ PM10 specially reaches the highest value, increased from 53.5% to 87.2%. It can indicate that the main pollution sources are fine particles from man-made pollution. Others, PM2.5/TSP and TSP are not strictly proportional relationship. The concentration of the elements in TSP is higher than in PM2.5, which are primarily present in coarse particles. While the contribution of S is the highest among them, in particular the contribution of S in PM2.5 reaches 33.8%. This is mainly due to coal-fired in winter, and fine particulate accounts for large percentage in coal dust.
