Air Pollution and Prevention Measures in Handan

Objective To investigate the current situation of air pollution and the prevention and control of air pollution in Handan. Methods Investigating the industrial structure in recent years,analyzing the main pollutants,such as SO2,NO2 and PM10in the air in 2006—2012. Results The average content of SO2 was 0. 050 mg / m3in2006—2012,which was higher than the national secondary standard in 2006 and 2007. The average content of PM10 was 0. 099 mg / m3 in 2006—2012,which was higher than the national secondary standard in 2006—2009 and catch up to the national secondary standard in 2010—2012. The maximum value of NO2 appeared in 2006( 0. 038 mg / m3),and the minimum( 0. 025 mg / m3) appeared in 2011,the concentration of NO2 were in line with the national standard in 2006—2012. The maximum air pollutants appeared in the winter and the air pollution was more serious in winter than in summer. Conclusions PM10 was the primary air pollutant in Handan,which was mainly originated from industrial waste gas,soot emission,coal combustion,traffic and urbanization. Based on the source of pollutants in Handan,some useful measures for the prevention and control of air pollution were proposed.
