Direct determination of mercury at the sub-picogram per gram level in polar snow and ice by ICP-SFMS
An analytical method for the direct determination of mercury (Hg) in polar snow and ice cores and surface snow based on inductively coupled plasma sector field mass spectrometry (ICP-SFMS) has been developed. Various Hg isotopes, such as Hg-199, Hg-200, Hg-201 and Hg-202, appear to be free of polyat...
