Abstract

Background and Aims: LEAD is an important environmental constituent widely used in industrial processes for production of synthetic materials and therefore can be released in the environment causing public exposure especially around the industrial residence area. For evaluation of human exposure to trace toxic metal of Pb (II), environmental and biological monitoring are essential processes, in which, preparation of such samples is one of the most time-consuming and errorprone aspects prior to analysis. The use of solid-phase extraction (SPE) has grown and is a fertile technique of SAMPLE PREPARATION as it provides better results than those produced by liquid-liquid extraction (LLE). The aim of this study was to investigate factors influencing sample pretreatment for trace analysis of LEAD in biological samples for evaluation of occupational exposure. Method :To evaluate factors influencing quantitative analysis scheme of LEAD, solid phase extraction using mini columns filled with XAD-4 resin was optimized with regard to sample pH, ligand concentration, loading flow rate, elution solvent, sample volume (up to 500 ml), elution volume, amount of resins, and sample matrix interferences. Results: LEAD was retained on solid sorbent and eluted followed by simple determination of analytes by using flame ATOMIC ABSORPTION SPECTROMETERY. Obtained recoveries of the metal ion were more than 92%. The amount of the analyte detected after simultaneous pre-concentration was basically in agreement with the added amounts. The optimized procedure was also validated with three different pools of spiked urine samples and showed a good reproducibility over six consecutive days as well as six within-day experiments. The developed method promised to be applicable for evaluation of other metal ions present in different environmental and occupational samples as suitable results were obtained for relative standard deviation (less than 10%). Conclusion: This optimized method can be considered to be successful in simplifying SAMPLE PREPARATION for trace residue analysis of Pb in different matrices for evaluation of occupational and environmental exposures.
