With the rapid development of industry, heavy metal contamination is becoming among the most important environmental problems causing worldwide concern. The purpose of this study was to evaluate the level of soil heavy metal pollution in the semi-arid areas of Northeast Algeria. To evaluate the ecological state of soils, we investigated fifteen sites. The level of heavy metals (HMs) toxicity and soil characteristics likr pH, electrical conductivity, organic matter, calcium carbonate, calcium, sodium, magnesium, phosphorus, nitrogen, and potassium were assessed during this study. The results showed that the mean values of heavy metals were as follows in ppm: Zn (41.197 ± 37.328), Fe (1.281 ± 0.459), Cu (23.407 ± 27.905), Pb (68.567 ± 43.412) and Cd (4.463 ± 1.823). Almost all of the soil was unpolluted by Fe and Zn, and a few were slightly polluted by Pb and Cu. High Cd concentration determined throughout this analysis is alarming. This study offers a thorough examination of soil heavy metal pollution in Northeastern Algeria to obtain soil pollution proportions of great significance for the comprehensive evaluation and control of soil pollution.
