A review on Air Pollution Tolerance Index (APTI) and Anticipated Performance Index (API)

Abstract

Now a day’s air pollution is one of the serious problems around the world. Plants can filter the air via-aerial elements particularly through twigs, stems, leaves, etc. Afforestation program is the best way to control the air pollution. Air pollution tolerance index (APTI) is an intrinsic quality of trees to control pollution problems, which is currently of major concern of urban localities. The trees having higher tolerance index rate are tolerant towards air pollution and can be used as a source to control air pollution, where as the trees having less tolerance index can be used as an indicator to know the rate of air pollution. By combining biochemical and aggregate factors the Anticipated Performance Index is prepared, which is also helpful in green belt development. The present review is based on the assessment of APTI and API potential of different plants for mitigating air pollution
