Observational Study on Atmospheric Particles Mass Concentration in Fushun in China

Abstract:

The variations of the atmospheric particles mass concentration, their pollution condition, and their relationships to visibility and wind speed have been studied by using the continuous concentration data of monitoring instrument GRIMM180 from Fushun air component monitoring station in 2009. The results show that the mean mass concentrations about PM10 and PM2.5 are respectively 0.073 ㎎/m3 and 0.048 ㎎/m3, and their daily average concentration has a large variation range. The ratio above air quality standard about PM10 daily average concentration is 5.9%, and the atmospheric particles exist mainly in the form of fine particles. The atmospheric particles mass concentration and the visibility show negative correlation, and the finer the particles are, the more they affect visibility. In general, the atmospheric particles mass concentration will gradually decrease with the rising of the wind speed. When the wind speed is more than 1.0 m/s, there is an obvious dilution effect on particles mass concentration, and when larger than 4.5 m/s, the relevance is not highly apparent.
