Abstract: A rapid analysis of methylmercury (MetHg) in fish samples is reported by using stannous chloride reduction and direct sampling electrothermal vaporization atomic absorption spectrometry (ETV-AAS). After the simple reduction reaction using 10% SnCl2 (w:v), Hg 2+ was changed to volatile Hg 0 and vaporized from the analyte extraction solution. Then, the residual Hg species was determined with the direct sampling Hg analyzer without requiring chromatographic separation. Since the dominating organic Hg in fish tiss…
