Impact of steel industry waste on physico-chemical property of soil

Abstract

Industrialization, urbanization and modern civilization have lead to fast degradation of our natural resources like water, soil and air mainly. Soil resource is the important natural resource. Without it survival of life is not possible because it completes our daily indeed and supports our life. But after industrialization soil nutrient quality has been affected. There are so major and minor industries in our country that causing pollution and deteriorating our life. Steel plant is also included in the list of major industry and our paper entitle on study of effect of steel industry waste on physic chemical property of soil. Steel production at an integrated steel plant involves three basic steps. In first step, the heat source used to melt iron and ore is produced. Next the iron ore is melted in a furnace and finally, the molten iron is processed to produce steel. The iron and steel industry involves a myriad of operations which generate vast volumes of air emissions, liquid effluents and solid wastes. This article presents an overview of impact of steel industry on soil nutrient quality. 20 Samples were collected from different places of JSL(Jindal Strips Limited) steel plant of Hisar district(Haryana). The quality analysis has been made through physical parameter (WHC, Bulk density, Colour, pH) and chemical parameter (Sulphates, Phosphate, Na+, K+, Org.C, Chloride ion, Ca +2, Mg +2). A systematic calculation of the correlation coefficient has also been carried out between different analyzed parameters. Comparative studies of samples were conducted and it was found that soil is not acidic in nature, it is alkaline soil which have pH in range of 8.1 to 11.6. Value of calcium and magnesium is very high of sample no.11 & 17-20(wall of industry & slag dumping side) and these are the major nutrient for plant growth. © 2010.
