ASSESSMENT OF HEAVY METALS CONCENTRATION IN ROADSIDE SOILS NEAR AN ALGERIAN NATIONAL ROAD ......

The contamination of soils along a road in western Algeria by heavy metals is assessed and quantified in this study (RN35, Tlemcen). Standard techniques and atomic absorption spectrometry were used to determine the physicochemical properties of soils and total heavy metal contents, respectively. Most of the soils were contaminated with cadmium, lead, and zinc, with concentrations ranging from 1.47 to 3.00 mg/kg for Cd, 8.00 to 39.75 mg/kg for Cu, 16.75 to 301.25 mg/kg for Pb, and 68.00 to 1952.50 mg/kg for Zn. Seven soil samples have a pollution index greater than one, indicating significant polymetallic pollution. In order to reduce concentrations of these pollutants and avoid their introduction into the environment and contamination of groundwater, wildlife, and local flora, monitoring measures and reductions in lead content in gasoline should be considered.
