Air pollution is one of the serious environmental issues that increase day by day due to anthropogenic activities. The demand for urbanization has made it even worse these days. Tiruchirappalli city is the 4th largest and one of the oldest cities in Tamilnadu. To keep the city’s development environment-friendly, it is necessary to keep an eye on the air pollution indices of the city. This can help the city planners to create a pollution-free and sustainable city. Planting the right trees in the city can help in reducing the effects of air pollution. This study depicts the effects of air pollution indices concerning various local plant species in Tiruchirappalli city. The methodology of the study involves the collection of 30 leaf samples from local plant species in two types of locations- one in a residential area (Edamalaipattipudur) and another in a transport line (Tiruchirappalli – Karur National Highway), both within the city limit. 15 samples from each site were collected and tested in the biological laboratory for the Air Pollution Tolerance Index (APTI) and Anticipated Performance Index (API). Land Surface Temperature (LST) and Normalized Difference Vegetation Index (NDVI) maps of the study area were created using MODIS data. The Air Quality Index was calculated for the major pollutants like So2, No2, PM 10, and PM 2.5 from five air quality monitoring stations in the city. Geographic Information System (GIS) and biological assessments conjointly aid in monitoring the air quality and its effects on plants and humans in the study area.
