Abstract
The present study was conducted for identifying the important heavy metals present in the road dust and at the same time biomonitor them using Calotropis procera and Delbergia sissoo leaves. The study clearly indicated that both the plants can be used as biomonitor for As, Pb, Fe, V, Cd, Cr, Zn and Cu. The heavy metals were estimated using AAS-7000 (Shimadzu). Reason for selecting the plants were their abundance in the area and high air pollution indices. Presence of these heavy metals in the road dust can be attributed to the red soil and more importantly thermal power plants operating in the study area. Since plants are able to capture the road dust, they can also prevent the particulate pollution which is having adverse health impacts for humans.

Keywords biomonitor;road dust;speciation;heavy metals.
