内容記述 | Surface snow samples were collected in the area near Syowa Station, Antarctica, with contamination-free technique. Snow samples were melted and filtered with a membrane filter (Nucrepore, 0.4μm pore size) in a clean room. The filtrates were analyzed for B, Na, Mg, Al, Si, K, Ca, Ti, V, Mn, Fe, Cu, Zn, Sr, Cd and Pb by inductively coupled plasma emission spectrometry (ICP-AES) and Cl^-, NO_3^- and SO_4^<2-> by ion chromatography (I.C.) after evaporation preconcentration by a rotary evaporator. Particulate matter trapped on the filter was analyzed by ICP-AES after acid digestion with HNO_3+HClO_4+HF (10 : 1 : 1). From the comparison with those results and average chemical composition of seawater and earth crust, the origin of elements in the snow was estimated; B, Na, Mg, K, Ca, Sr, Cl^- and SO_4^<2-> are derived largely from seawater and Al, Si, Ti, Mn and Fe from earth crust. The origin of other elements could not be clearly specified. | |||||||||||
