Abstract:
In modern times air pollution has become a menace for the survival of all living beings. The use of plants in cleansing the environment and for abatement of pollution and improvement of environment is an effective way which is well recognized throughout the world. Different plant species respond differently to air pollution with certain species being very sensitive and shows visible and measurable symptoms, while some others may be highly tolerant to air pollution. The morphological damage of plants is generally visible through lesions on the aerial parts, while the biochemical and invisible physiological changes can be measured and quantified. From various researches of different researchers across the globe, Anticipated Performance Index (API) and Air pollution tolerance index (APTI) in combination has proved to be an innovative ecological approach in selecting plant species for reducing air pollution. This review suggests that a combination of APTI and API can be of immense importance for the evaluation of plant responses to a variety of pollutants for green belt purposes. Plants having high APTI and API value can be selected for the green belt improvement and long term air pollution management in city and developed areas.
