One of the prominent and unavoidable cases in environmental sciences is the contamination problem. The present project is a part of a research proposal which was fundamentally defined for evaluation the type and quantity of the main pollutants present in the waste water of electroplating industries located in the vicinity of dye, drug, repairing plants in the eastern regions of Tehran. After sampling and pretreatment step, the samples were analyzed by flame atomic absorption spectrometry (FAAS) and inductively coupled plasma atomic emission spectrometry (ICP-AES) using external calibration graphs. The experimental results revealed that the main constituent component of the wastes involves chromium. Furthermore the other trace metals are Pb, Cd, Fe, Cu and Mn.
