The aim of study was to evaluate the suitability of industrial effluent for irrigation purposes and their possible effects (due to heavy and trace metals) on the germination as well as quality of agricultural crops. The effluents (liquid waste) of five industries like textile mill, oil refinery, soap and detergent, hydrogenated oil and rubber industry were used in this study. The study was carried out during 1998-2000. The results show that effluents from all five industries consist of higher concentration of metals (Cr, Mn, Fe, Cu, Co, Ni, As, Cd and Pb). Furthermore the germination of crops was more effected with the effluents of textile mill followed by soap and detergent, oil refinery and hydrogenated oil, where as less effects were observed from effluents of rubber industry. Therefore it was observed that effluent is not only unfit for irrigation but also for domestic uses due to presence of heavy and toxic metals and other harmful pollutants.
