Abstract
This study describes the determination of lead and pH in Setif soils. Soil samples from the town of Setif were taken from a total of 100 subsurface soils, systematically sampled (regular 1 × 1 km grid). The lead concentration was determined by atomic absorption and the average lead concentrations ranged from 24 to 384 mg kg−1. The distribution of the different concentrations of lead and iso-concentration was distributed on the map of the exchange site with Arc GIS software. Compared with their local soil background values, higher concentrations of Pb were observed to different extents. The distribution of Pb concentrations has been explained by urban traffic.
