摘要：
Roadside Plants (Eucalyptus and Guaiacum officinale) from controlled and polluted areas of Karachi city were analyzed for heavy metals. Leaves of these plants were taken for the study. Atomic Absorption technique was employed for the analysis. Levels of Pb and Cu were found to be elevated in leaves of industrial and high traffic density areas. Rain was found to influence the metal concentration. Ph and Co levels increased while Cu, Ni and Cd levels got decreased following rain. The collected data manifests that automobile exhaust and industrial wastes in urban areas of Karachi are causing pollution.
