Abstract
Levels of some heavy metals in soil and vegetation along a major highway in Libya were detent by Atomic Absorption Spectrophotometry. The concentrations of Pb, Cd, Ni, Zn, Cu, Cr and soil and vegetation all decreased with distance from the road, indicating their relation to traffic, concentrations of the metals also decreased with depth in the soil profile indicating that the s of the metals was aerial deposition from motor vehicles. Inter-relationships between metals in soil were highly significant (p < 0.05) suggesting a common source for these metals. Pb and Zn were found to be deposited more than the other metals. Average values for citrus lemon leaves generally 30 - 65 % of those for Olea europaea leaves. In most cases, between 20-40% of the metals was removable by simple washing with water, indicating that a significant, but not predominant fraction of the metals is in the form of easily-removed particulate matter. Discussion of the results study is based on statistical treatment of the data. |
