Lead in particulate deposits and in leaves of roadside plants

Abstract

Lead concentrations were determined for particulates, which were deposited on the leaves of roadside plants in Bursa city of Turkey. The particulates were collected from the leaves and the lead accumulated by the leaves of different species were also measured. A statistically significant correlation was found between the number of passing petrol-fueled vehicles and lead concentrations in the deposits at different designated sites. However, no significant correlation was found between concentration in the deposits and lead accumulated by the leaves. A lead concentration of 32.00 +/- 6.8 ppm was the highest concentration in the particulate deposits, while maximum lead accumulated by the leaves was noted as 3.15 +/- 1.12 ppm.
