The present learn is carried to find out Air pollution tolerance index standards of twenty plant species growing around Panyam cement factory, Bethamcherla mandal of Kurnool district, A.P., India to recognize the plant species that are forbearing to grown up in cement dust polluted areas. The study revealed an increase in their APTI values in eight species and indicated that these 8 species may be more tolerant to the stress caused by cement dust pollution. The highest percentage increase of APTI is recorded in Ficus benghalensis (94.61), followed by F.religiosa (54.78), Terminalia catappa (46.57), Leucania leucocephala (35.45) and Mangifera indica (32.03). They can also capable to raise water table of the soil by plummeting temperatures of the area due to their increase in population and by covering the soil surface with their huge canopy.
