|Title:||CARACTERISATION OF CEMENT’S DUST AND TOTAL HEAVY METALS CONTENT IN SOIL OF SELECTED LOCATIONS AT THE CEMENT PLANT - MEFTAH-BLIDA|
|Abstract:||As the population of the world increases, the need of housing rises as well. The cement industry grows too. This industry has a major role in the instability of the environment and produces many air pollution hazards . Cement is produced from geological materials that contain CaO, SiO2, Al2O3 and FeO in certain proportions to define the main properties of cement . One of the most critical impacts of cement manufacturing is the dust generated during transport, storage, milling, packing, etc . Atmospheric dust is an important source of air pollution particularly in dry climates, hence air pollution has potentially harmful or nuisance effects on human beings, animals, plants, their biological communities and habitats and on the soil . It has been reported that 1 kg of cement manufactured in Egypt, generates about 0.07 kg of dust in the atmosphere . Previous studies have determined that cement dust falls are enriched in toxic heavy metals such as As, Pb, Ni, Cr, Cu, Zn,Mn, and Cd, , which can spread throughout a large area by wind, rain, etc. and accumulate on plants, animals and soil, t h u s ultimately affecting human health . Heavy metals can cause damage to brain and nervous system, increased blood pressure, affect on gastrointestinal functions and reproduction .When considering different kinds of soil pollutants; heavy metals are especially dangerous because of their persistence and toxicity . Al-Khashman and Shawabkeh  studied the metal distribution in soils around a cement factory in southern Jordan and found that all of the metals were concentrated on the surface of the soil, and highest metal concentrations were found close to the cement factory. Therefore, it is of major interest to improve the knowledge on heavy metal sources and their concentrations in topsoil’s, as these factors might influence the human population and the ecosystem compartments. Due to the availability of rawmaterials necessary for themanufacturing of cement andmeasures taken by the government of Algeria to encourage and facilitate investments in the country, a cement factory had established in Meftah municipality since 1976 as well to meet the increasing demand for cement. The objective of this paper is to identify and evaluate the levels and sources of dust and heavy metal in agricultural and residential topsoil’s in the Meftah vicinity|
