Abstract
Arsenic in the sediments of Lake Usori (Usori-ko or Osoresan-ko) and L ake Mashu (Mashu-ko) has been characterized by X-ray photoelectron spe ctroscopy (XPS) and X-ray induced Auger electron spectroscopy and show n to exist as sulfide and arsenite, respectively. In the Lake Mashu se diment, surface concentration of As determined by XPS was significantl y higher than the average concentration.
