Abstract

Environmental pollution by metals became extensive as mining and industrial activities increased in the late 19th and early 20th century the current world wide mine production of Cu, Cd, Pb and Hg is considerable. They present a risk for primary and secondary consumers and ultimately humans. This study was carried out to investigate the effect of explosive industry effluents on soil characteristics. Field experiment was conducted in and around Rajasthan explosive and chemical limited in Dholpur in Rajasthan. Waste water and soil samples were collected to determine pH, Ec, TDS, Organic carbon, Cu, Pb. Effluent from explosive industry show differences in levels of pH 7.9 to 8.5, electrical conductivity 0.65 to0.95s, TDS 1825 to 2500mg/l, and heavy metals like Cu 2.40 to 3.70 mg/l and Pb 0.32 to 0.48 mg/l maximum than permissible limit. Soil analysis show differences in levels of pH 8.0 to 8.7, electrical conductivity 0.25 to 0.40s, organic carbon 0.22% to 0.68% and heavy metals like Cu 150 to 225mg/kg, Pb 550 to 725 mg/kg were higher than permissible limit.
