Scanning proton microprobe analysis of a series of Fe-sulfides (pyrite and marcasite) from the Manchester coal bed, Clay County, eastern Kentucky, demonstrated that Hg could be detected in some grains. The low concentration of Hg in coal, and even in

Scanning proton microprobe (SPM) analysis and imaging was used to map the distribution of zinc in otoliths of anadromous and non-anadromous Arctic char (Salvelinus alpinus) from the Canadian Arctic. Zinc distribution patterns were oscillatory with co

Micro-PIXE analysis of trace elements in otoliths has been used as the basis for several projects on char, a fish that is important for aboriginal subsistence fisheries in Arctic Canada. Life-history patterns were originally inferred from micro-PIXE
