Abstract
Nowadays, air pollution is a very vital environmental issue. During rapid industrialization, anthropogenic activities result in a wide array of pollutants which are released to atmosphere and absorbed by the leaves of plants. Atmospheric pollutants have negative effects on woody plants. Airborne pollutants like oxides of sulphur (SOx), oxides of nitrogen (NOx), Ozone (O₃), particulate matter (PM), volatile organic compound (VOC), lead (Pb) can change the morphological, physiological and biochemical characteristics which can be deleterious in nature. Air pollution can dis-balance various enzymatic activities which can reduce various types of physiological processes such as, photosynthesis, respiration, transpiration but plants can scavenge and detoxify significant amounts of air pollutants which are effective in cleaning air. In the present paper, effects of different airborne pollutants on plants have been reviewed.
