Abstract:-
Air pollution, caused by vehicular emissions, industrialization, and population growth, increases harmful gases like Sulphur dioxide, carbon dioxide, and carbon monoxide, harming vegetation, animals, and humans. Plants can effectively monitor air pollution as their leaves act as absorbent and provide large surface area for the absorption of particulate matter. A study in Kurukshetra, Haryana, analysed leaf dust accumulation in various plant species to map particulate matter pollution. Results showed that Dalbergia sisso, Ficus benghalensis, Ficus religiosa, and Azadirachta indica leaves had higher dust accumulation in polluted sites compared to control sites.
