Analysis of Environmental Materials with Correlation between PM2.5 and Other Indexes in AQI of Wuhan

Abstract:

Fine particulate matter PM_2.5 is the main factor of "Haze” weather. The paper chose the content of various indicators in the sets of air quality index AQI detected by a monitoring station in Wuhan city as samples. Based on the methods of Spearman's rank correlation coefficient and Kendall rank correlation coefficient to establish mathematical model, the paper analyzed the correlation between the content of PM_2.5 and other five basic detection indicators and corresponding pollutants, with providing theoretical and experimental evidence for air management work. Two methods of the experiment results showed that PM_2.5 (content) has a strong correlation with sulfur dioxide, nitrogen dioxide, particulate matter, carbon monoxide (content), and had a negative correlation with ozone (content).
