In order to study the lead levels in air, soil and water in the vicinity of various Lakes and Dams within the Pakistan, Samples were collected periodically from the selected sites for the three media, and were analyzed by AAS. This investigation on Lakes and relevant air / soil / water showed that maximum concentration of Pb were 717.5 μg/M3, 44.9 mg/ kg and 217 μg/L in air, soil and water respectively. Analysis based on statistical parameters evidenced a positive correlation between air- soil, air- water and soil- water systems. The values of X and G.M, emphasized a randomize distribution of Pb contents in the three media. Elevated Pb levels were determined at Khan Pur Dam in case of air and water system, while at Rawal lake in case of soil samples. Quaid-i-Azam University Lake was found free from Pb because Pb levels were below detection limits i.e. not detectable in case of water.
