Sensitive determination of methylmercury δ13C compound specific stable isotopic analysis by purge and trap gas chromatography combustion isotope ratio mass spectrometry

Despite several decades of mercury research, answering fundamental questions on where and how methylmercury (CH3Hg) toxin is naturally produced in aquatic ecosystems, is still highly challenging. Investigating complex and/or coupled processes in the context of global changes requires new high-resolution analytical tools. The purpose of the compound specific carbon stable isotopic analysis (δ13C-CSIA) of the methyl group of methylmercury (CH3Hg),...
