Certain trees and crops that are native to India have been found to be effective in combatting air pollution, according to a new study.


The level of Ascorbic acid in plants determines their tolerance against the adverse effect of oxidising pollutants (the higher the ascorbic acid, the higher the tolerance)


Trees with high Air Pollution Tolerance Index (APTI) (a tool used to assess the tolerance capacity of tree and crop species against air pollution) value are pipal, neem, mango and crops like maise, pigeon pea and safflower.


Ascorbic acid (vitamin C) is involved in regulating photosynthesis, hormone biosynthesis, and regenerating other antioxidants.


Usage: The example of these native trees can be cited for greening Urban airspace to curb air pollution.
