Study on Concentration Characteristics of TSP, PM₁₀ and PM_2.5 in Harbin

Abstract:

In order to investigate the concentration characteristic of atmospheric particles, TSP, PM₁₀ and PM_2.5 were collected in July 2008 to June 2010. This study investigates the mass concentration of atmospheric particles in each month. The results show the three particle concentrations reached the lowest value in July, while the peak in January. Compared with the national secondary standard, TSP and PM₁₀ were exceeded in January, February, March, April, November, and December and PM_2.5 concentrations is above 2 to 8 times of the EU standard (15 μg/m³). Fine particles (PM_2.5) and coarse particles (PM_{2. 5-10}) are major component of atmospheric particles. The mass concentration of atmospheric particles on day is higher than at night in major months and lower in May and June. However, it is not obvious in July, August and September.
