Analysis of the change of the primary pollutants in urban air<br>Li Lixia 1, Wang Liang 1, Chen Furong 2, Jia Jing 1<br>(1. Jiyuan environmental monitoring station, Henan Jiyuan 459000; 2. Jiyuan environmental monitoring detachment, Henan Jiyuan 459000)<br>Abstract: Based on the monitoring data of the main pollutants in the ambient air of a city in Henan Province from 2015 to 2018, this paper analyzes the daily average compliance rate, annual average concentration and the proportion of the main pollutants in the total pollution days, and uses the Spearman rank correlation coefficient trend test to analyze the trend of various pollutants. The results show that from 2015 to 2018, the pollution degree of inhalable particles and fine particles in a city of Henan Province shows a certain trend of improvement, and the pollution degree of ozone factor shows an aggravating trend. Ozone has become the main pollutant affecting the air quality of the city. Finally, the corresponding control measures are put forward.<br>Key words: ambient air quality; primary pollutant; Spearman rank correlation<br>
