Study on correlation analysis of TSP, PM10 and PM2.5 in atmosphere

The cross of Jiefang Road and Renmin Street in Changchun is selected as the research site to carry out the sampling and analysis of TSP, PM10 and PM2.5. Then the correlation analysis is made to the monitoring data using the regression analysis method and t-TEST method. The correlation coefficients of elements contents in three pollutants are as follows: 0.9349 for TSP and PM10, 0.8797 for PM2.5 and PM10, 0.7824 for TSP and PM2.5. The statistical values of t-TEST are as follows: 0.90103 for TSP and PM10, 0.04745 for PM2.5 and PM10, 0.047986 for TSP and PM2.5. It is obvious that the correlation for TSP and PM10 is superior; the correlation for PM2.5 and PM10 is followed. The results can provide the scientific basis to the related Environmental Management Activities.
