    Speciation analysis of mercury employing volatile species generation: Approaches to reliable determination in blood and hair

  • Original language description

    A simple and short (7 min) two-stage extraction procedure was proposed for simultaneous determination of Hg2+, MeHg+ and EtHg+ in human blood. Acceptable extraction efficiency of Hg species without their inter-conversions was confirmed by analysis of certified reference materials resulting in recoveries better than 90% (Hg2+, MeHg+) and 80% for EtHg+, respectively. HPLC separation and following post-column volatile species generation (VSG) steps were optimized to achieve the best analytical performance employing ICP-MS detection. VSG step enhances sensitivity 30–40 times and improves limits of detection (LOD) by a factor of five in comparison with the setup without VSG step. Extraction selectivity of MeHg+ from human hair matrix was verified by HPLC-ICP-MS and applied to both certified reference material and real samples.
