The effect of industrial effluent contaminated sewage water on the content of micro and potentially toxic elements in soils and potato plants was studied. The elemental composition of the sewage water changed due to the contamination from the tannery effluents. The increase in Cr was so dramatic. It increased from 2.7 mg/kg in the control soils to 14 mg/kg in soils irrigated with the contaminated water. The soils of the study area were generally light textured and there was a build up to 30 cm or lower depth. The release of wastewater into the environment polluted not only the irrigated soils but also plants growing in these irrigated soils such as potatoes and onion. Due to disposal of industrial effluents, the waste waters have higher contents of Cu by 42 times, Fe by 155, Mn by 98, Zn by 31, Al by 50, As by 4, Cr by1400 and Ni by 52 times over the tube well water We observed that the concentrations of the contaminating elements were higher in potato and onion the buildup of Cu and Zn was higher in soils than in the vegetables grown in the contaminated soils suggesting a decreased absorption by the plants. Contrary to Cu and Zn, the absorption of Cr and Ni by potato plants and its distribution in inedible non-edible parts was proportional to its build up in soil.
