Abstract
Lead concentrations were determined for particulates which were deposited during one year on the leaves of roadside plants in Karachi. The particulates were collected from the leaves at a height of one metre. The lead accumulated by the leaves of different species was also measured. A statistically significant correlation was found between the number of passing petrol driven vehicles and the lead concentration in the deposits at different designated sites. However, no significant correlation was found between the concentration in the deposits and the lead accumulated by the leaves. A lead concentration of 30.00±6.6 ppm was recorded as the highest concentration in the particulate deposits, while maximum lead accumulated by the leaves was noted as 3.12±1.09 ppm.
