Quantification of ground pollution by lead and zinc in relation to the road traffic (cases of the town of Sidi Bel Abbes, Algeria west)

ABSTRACT: Within the framework of an impact study of the road traffic on the degrees of pollution of the grounds by Lead and Zinc, samples of substrate were collected and analyzed along the periphery which buckles the town of Sidi Bel Abbes, in the west of ALGERIA. The contents revealed by proportioning by atomic spectrometry of absorption with flame, along the transect clearly show a considerable accumulation with variable concentrations out of lead and zinc in relation to the road traffic. The estimate of the mobility of the two elements studied compared to the distance from the roadway highlighted a decreasing dynamics of the pollutants proportionally related to the distance of the source of pollution. The Hydrogen potential, cation capacity of exchange, and the fraction clay are physicochemical parameters to take into account to interpret the contents revealed of pollutants.
