Abstract
The analysis of lead, zinc and cadmium in Bahrain refinery sludge collected from various deposition sites at Bahrain petroleum company (BAPCO) are reported. Atomic Absorption spectrophotometric method, both flame and flameless (graphite furnace) techniques, were used for the analysis. The concentrations of lead, zinc and cadmium were found in the range, 66.1 to 14630.9 mg/kg (0.007% to 1.46%), 47.4 to 1791.1 mg/kg (0.005% to 0.17%), 0.24 to 5.40 mg/kg (0.00002% to 0.0005%), respectively. These concentrations are less than 1% as is accepted internationally. Nevertheless, these are hazardous and should be managed properly.
