| Popis: | An improved method is described for the determination of methylmercury (MeHg) in human hair that is based on thin-layer chromatography and thermal decomposition gold amalgamation atomic absorption spectrophotometry. The dithizone extraction and application procedure of this technique were optimized, thus improving its sensitivity and robustness and enabling the use of less toxic solvents than other approaches. The limit of detection was 0.18 ng MeHg (as Hg), corresponding to 0.018 mg MeHg kg |
