Air pollution, is now almost inescapable component of urban life effecting both plants and animals equally. The changes in the epidermal configuration reveal marked alteration in number of stomata, epidermal cells and stomatal indices in leaf samples collected from polluted zones that can be used as biomarkers of air
These pollutants not only affect the morphology of plants but also alter the physiology. Reduction in various parameters of the two plant species studied from polluted sites clearly indicate the deleterious effect of air pollution on plant health.
It is evident from the present study that the air pollutants such as SPM, SOx, NOx
and O3 from automobile exhaust and industries along with many other unknown pollutants are responsible for bad air quality and are responsible for altering the epidermal structures in both Tridax and Datura plants growing in polluted zones.
