A Review on the Effects of Environmental Factors on Plants Tolerance to Air Pollution

Abstract

Due to unsustainable, unplanned, and rapid development, air pollution has become a universal problem. Physical and chemical methods have come up with a tremendous solution but they have been proven insufficient to address this problem on a large scale. The better and natural way to overcome this problem is by plantation. Plants can adsorb, absorb and impinge pollutants on their leaf surfaces but all plants do not show the same response to a particular type of pollutants under the same geographical conditions. There are certain biochemical parameters (such as chlorophyll content, pH, ascorbic acid content, and relative water content) on which plants are selected for plantation so far in polluted areas. These parameters are not only sufficient to evaluate the tolerance of plants towards pollutants. Biochemical parameters depend upon environmental conditions and the concentration of air pollutants. The present review was an effort to investigate the various environmental factors which play a pivotal role in modifying the biochemical parameters and how it eventually affects the plants' tolerance to air pollutants.
