Copper and chromium contents in sewage sludge were determined by using atomic absorption spectrometric method. Sludge samples were collected from Misrata , Msallata and Tarhünah municipal wastewater treatment plants during six months. The concentrations of Cu and Cr in all sludge samples varied between 81.0-299.6 and 21.8-232.8 ppm respectively. The concentrations of copper and chromium were below the Permissible limits of sewage sludge usage in agriculture in China and Netherlands guideline value.
