Atomic absorption spectrophotometer technique was employed to measure the contents of the heavy metals in the effluents directly released from tannery industries. These effluent samples were first subjected through wet acid digestion process for decomposition of organic substances and concentration of the metals being measured in the samples. The measured concentration of the heavy transition metals by AAS technique was analyzed and it was concluded that this spectrophotometer method can analyze a remarkable concentration of the effluents metals. Therefore, the quantitative measurement of most of the metals in tannery waste is preferable by AAS method. These results overall give a picture that the environments are greatly being contaminated due to high Cr, Fe, Pb concentrations as well as other toxic chemicals found in the discharged effluents from tanneries
