ABSTRACT

 

Trace elemental analysis was carried out in the leaves of Azadirachta indica and Pongamia glabra, collected from different environmental sites of Visakhapatnam, India using particle induced X-ray emission technique. A 2MeV proton beam, collimated from 3MV pelletron accelerator at the Institute of Physics, Bhubaneswar, India was used to excite the samples. The elements K, Ca, Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, Br, Rb, Sr and Pb were identified and their concentrations were determined. High levels of Cr, Mn, Fe, Ni, Cu, Zn and Pb accumulated in the leaves of Azadirachta indica and Pongamia glabra collected from two regions in the vicinity of industrial area compared to control region clearly indicate the source of industrial pollution.
