Dispersion analysis of Particulate Matter for Sustainable campus

Atmospheric pollution has increased in higher concentration in day-to-day life. Many sources of pollution cause heavy damage to human beings, monuments, and other living and non-living organisms. The pollutant dispersion varies as spatial, temporal, and spatiotemporal variation. The study was done in Kumaraguru College of Technology (11.079458oN & 76.989494oE), as it is known as a sustainable campus in Coimbatore city. The campus is covered with 4200 trees with an average of 10,000 students, working and non-working staff. Four locations (Main gate, Security office, Bus parking, Girl’s hostel) were spotted, for analyzing PM10 on the campus using a respirable dust sampler. Collection of data and tabulating data from different locations on campus, a map to understand the dispersion of PM10 was created. Spatio-temporal interpolation using QGIS open software and the IDW (Inverse Distance Weighted) method was used. The study concluded that there is some variation in dispersion levels inside the sustainable campus. Comparison of results with TNPCB air quality standards. The contours for dispersion analysis done after interpolation mapping. This variation is noted by interpolation and contour mapping study using QGIS.
