摘要
通过对秦皇岛市2012—2013年的空气质量对比分析,得出2013年空气质量优良率明显下降,由2012年的96.5%下降到59.4%,其中,1月份空气污染最为严重,其次是8月份。秦皇岛市出现频率较高的前三个首要污染物分别为PM10、PM2.5、O3。提高秦皇岛市的空气质量应着重控制颗粒物和臭氧的排放及形成,更需注重1月份和8月份的空气质量状况。建议通过对重污染企业限排、机动车限行以及增加道路洒水次数等方法提高秦皇岛市的空气质量。
Through the analysis on the air quality in Qinhuangdao from 2012 to 2013, it was concluded that the rate of good air quality in 2013 decreased to 59.4% compared to 96.5% in 2012.The air pollution in January was the worst, followed by August. The most frequent primary pollutants were PM10, PM2.5and O3 respectively. The emission and formation of particular matter and ozone should be controlled to improve the air quality, especially the air quality of January and August should be paid more attention. Necessary measures should be taken to improve the air quality in Qinhuangdao, such as the limitation of pollution emission, the traffic controls and the increase of the road sprinkler.
