Risk of Heavy Metals Accumulation in Agricultural Lands by Treated Wastewater as Source of Irrigation in the Province of Batna (East Algeria)

Abstract

Volume 6 -Issue 1 and certain chemicals are the main hazards to human health through different pathways [4]. The metals that may be present in wastewater, Cadmium (Cd), Copper (Cu), Molybdenum (Mo), Nickel (Ni) And Zinc (Zn), can constitute a significant health risk for humans and animals and can also affect, in the long term, irrigated crops as a result of accumulation in the soil [5]. Irrigation with heavy metal contaminated water can deteriorate the quality of soil as well as the agricultural produce [6]. The main objectives of this study are primarily to quantify the concentration of these heavy metals (Cr, Cu, Pb and Cd) in irrigation wastewater; to see which lands of Batna and Timgad are far from the risk heavy metals contamination. Materials and Methods Study areaThe current study was carried during autumn 2017 in two regions of the province of Batna.
