Mercury speciation and stable isotopic composition in marine vertebrates: new insights and perspectives
Mercury (Hg) is a persistent toxic compound whose amount in the global biosphere has at least tripled since industrialization. Recently, the study of the seven Hg stable isotopes has emerged as a new promising technique affording to explore the Hg cycle both in situ and in laboratory. Mercury stable...

Mercury (Hg) is a persistent toxic compound whose amount in the global biosphere has at least tripled since industrialization.
