The direct mercury analysis of a single human hair strand using an induction heating-electrothermal vaporizer (IH-ETV) by inductively coupled plasma mass spectrometry (ICP-MS), was investigated. It was observed that IH-ETV-ICP-MS could easily determine mercury concentrations in a single hair strand using external standards calibration with powdered hair certified reference material (CRM). The detection limit achieved by this method was 20 pg of Hg for a 12 cm strand of hair which meant that only 0.4 cm of hair is needed to detect a natural mercury level of 1 μg g . The results show that just one hair strand is sufficient to estimate mercury levels in an individual which is much less than 100 strands required for traditional methods.
