This paper presents a procedure to determine total toxicity of the selected waste material from scrap mobile phones and their components.The assessment is based on literature data of quantitative analyses of heavy metals (Ag, As, Ba, Cd, Co, Cr, Cu, Hg, Ni, Pb, Se and Zn) in compliance with the TTLC (Total Threshold Limit Concentration) and TCLP (Toxicity Characteristic Leaching Procedure) procedures.Coefficients for toxic criteria equations have been selected on the basis of limiting and standardizing TTLC and TCLP values.The calculated total toxicity value on the basis of the metals content was also verified by comparison with the sum of limited and standard values.The final classification of the waste material total toxicity was found to be a function of determinable concentration levels in the mass of waste material (TTLC criterion) and leachable forms of metals (TCLP criterion).
