Abstract : Environmental pollution is currently global problem and its issue is crucial. There are struggles to enhance advancement of science and technology in one hand and to play down its major consequence, environmental pollution, on the other hand. The present study aimed to determine the levels of trace lead and cadmium in the waste effluents of MOENCO Garage, Felege-Hiwot Hospital and Textile Factory in Bahir Dar town, Ethiopia. The analysis for lead was performed using FAAS and UV/Vis after extracting the metal from the given sample solution via complex formation by dithizone complexing agent. Colorimetric prediction also justifies where the concentration of lead lies in reference with the colour of the standards. The concentration of cadmium was determined using FAAS. Method significance for lead analysis was tested by F-test through the analysis of variance and the first separation efficiency was predicted from the recovery test based on the second extraction process. Besides to this pH, Temperature and TDS of each sample were determined. Based on the finding the concentration at the point source of their waste effluent for lead is: 0.45 0.10, 0.12 0.10 & 0.31 0.20 and for cadmium is: 0.021 0.010, 0.004 0.002 & 0.031 0.010 in ppm units respectively. The results show that the discharges at each site do have significant amount of trace Pb and Cd at the point sources. It is expected for the minimization of the trace metal pollutants along the ways through sedimentation and others.
