Plants as vehicular pollution indicator

Article Abstract by: RADHEY     

Original Authors: Dr. Shashi; Dr. Anil K Dwivedi; Dr. Kailash Dubey
To study the impact of vehicular pollution on the road-side vegetation, four sites in the eastern Uttar Pradesh of India
with varying vehicular density were selected. Index of dominance of five plant species Ageratum houstonianum Mill., Argemone mexicana Linn., Rumex dentatus Linn., Salvia plebeja R. Br. and Solanum nigrum Linn. were studied at six intervals till 250 m perpendicular to the road at all the four sites. An attempt has been made to correlate the index of dominance of the species with the load of vehicular pollution. Three species, A. houstonianum, S. plebeja and S. nigrum, showed positive correlation with respect to the increasing distance from the road, showing its susceptibility for the pollution whereas A. mexicana and R. dentatus showed positive correlation with the increase in pollution  load. Thus, A. mexicana and R. dentatus were  advocated to be bio-indicators of vehicular pollution.
