Effect of Roadside Soil and Vegetation with Lead and Zinc by Motor Vehicles

Abstract
|
|
|
This report deals with lead and zinc contamination of roadside soil and plants caused by motor vehicles as a function of distance from the road edge. The concentrations of Pb and Zn in roadside soil and plant samples from several locations decrease regularly with increasing distance from traffic.
Soil samples up to 24m distance from the road edge are contaminated with more than 12.99 ppm lead, and 13.40 ppm zinc. The decrease in Pb and Zn contamination with increasing distance from the road is characteristically curvilinear; the relative coefficiency of Pb and Zn with distance is -0.69, -0.48, respectively. The average contents of Pb and Zn in plants are 21.5 ppm and 30.00 ppm.
It is suggested that the contamination is related to the composition of gasoline, motor oil and to roadside of the residues of this metals.
