An analytical method is described for methylmercury determination in fish and aqueous samples using solid-phase microextraction (SPME) followed by gas chromatography-atomic fluorescence spectrometry (GC-AFS). The procedure involves aqueous-phase derivatization of methylmercury species with sodium te
This paper presents a method capable of quantitatively separating sub-nanogram amounts of monomethylmercury cation (MeHg + ) and dimethylmercury from sediments by vacuum distillation at 40 Β°C and 6 m Hg pressure followed by hydride derivatization and atomic fluorescence spectrometric detection.
