Pollution stay in the atmosphere through chemicals, gases, particulate matter and disturbs all living organisms, environment. Intensity of pollution directly cause injury to plants. Hence, the present study was planned to assess the air pollution tolerance index of the plant at five different places in Salem, Namakkal District. The study results exhibited that all plants were found to be sensitive to pollution and needs to be protected from pollution in order to conserve plants in that locality. Plants selected from all the study areas fall under 1–16 category, which was categorized as sensitive. The maximum level of APTI reached by plants from the selected specific study area are as follows: Very few plants studied at Yercaud bus stand such as Erythrina indica (0.81), Mangifera indica (0.42), Tamarindus indica (0.28) was found to be very sensitive to pollution as they showed air pollution tolerance index value below 1, the remaining plants also showed value of APTI below 4.00. Hi Tech Kovai minerals – Artocarpus heterophyllus 10.17, SSM Processing Mills – Phyllanthus embelica-10.17, SIDCO Women's Park-Xanthium strumarium -10.90, Carica papaya-11.22, Quarry, Edappadi -. Ficusreligiosa-9.55, Eucalyptus grandis-9.37. Among the soil nutrient studied, the boron was found to be deficient in all the selected study area and Iron was low in soil sample studied near Hi Tech Kovai Minerals.
