Industrial effluents are ranked as the highest pollutants among all industrial wastes. The industry effluent is highly toxic to flora and fauna due to the presence of excess amount of dissolved solids, chlorides, sulphides, chromium with a very high BOD, COD and conductivity in the effluent From the Common effluent treatment plant (CETP), treated effluent was analyzed for physico-chemical characteristics and its effect on seed germination, á-amylase activity and early seedling growth and 100% of the effluent, suggested á-amylase enzyme dependent inhibition of seed germination. In contrast, compared to the control, shoot length, leaf length, á-amylase activity (IU/g) and fresh weight biomass (g/plant) of seedling found to decrease as the effluent concentration increased.
