Abstract
This research was carried out for the phyto-monitoring of pollution to check the effect of Pb2+ pollution on the spatio-temporal distribution of biochemical attributes resulting along Motorway M-2 and G.T. road Kharian to Taxila. The result showed that maximum decrease of total soluble sugars in Nerium oleander (0.023 mg/g F.wt) along M-2 and Calotropis procera (0.042 mg/g F.wt) along N-5, total free amino acid in Datura alba (0.501 mg/g F.wt) and Cenchrus ciliaris (0.62 mg/g F.wt) and total soluble proteins in Cenchrus ciliaris (3.91 mg/g F.wt) and Ricinus communis (0.73 mg/g F.wt) due to high concentration of Pb2+ (2.05-1.33 mg/kg dry wt.) along roadside. Findings may have their application as bio-indicators to perceive the occurrence of atmospheric pollutants on plants for identification and prediction of environmental hazards.
