                      (LA-ICP-MS) has been developed as reliable analytical
                      technique for the quantitation of metal distributions at
                      micrometre resolution. In this work a novel microanalytical
                      strategy for biomonitoring of arsenic, toxic and essential
                      metals in single hair strands is proposed. Two different
                      calibration strategies in LA-ICP-MS were developed using
                      either certified hair standard reference material (IAEA 086)
                      or prepared matrix-matched laboratory hair standards doped
                      with analytes of interest at defined concentration. Powdered
                      hair standards and human hair strands mounted on a sticky
                      tape in the LA chamber were analyzed under the same
                      experimental conditions by an optimized LA-ICP-MS technique.
                      The use of hair powder standard allows calibration curves to
                      be obtained by plotting the analyte ion (M+) intensity
                      normalized to S-34(+) (the ratio M+/S-34(+)) as a function
                      of the concentration determined by ICP-MS of acidic digests.
                      The linear correlation coefficients (R) of calibration
                      curves for analytes As, Ba, Cd, Ce, Co, Cr, Cu, Fe, Ga, Hg,
                      Mg, Mo, Ni, Pb, Rb, Sr, Ti and U were typically between
                      0.985 and 0.999. The limit of detection (LOD) was 0.6 mu g
                      g(-1) for As and ranged from 0.3 to 7.8 mu g g(-1) for the
                      other analytes. Distinct elemental exposition time profiles
                      were observed in hair samples from five volunteers. (C) 2011
