Fourt een chemical constituents w ere detected among all measured ones. T he enrichment fac t or method w as used to determine the possible origin anthropogenic, curst, oceanic, and mixing origins, of chemical constit utents in snow . T he S/ N a valuas suggest t hat SO4 2- , and NO3- are mainly from ant hro pogenic act ivities. Keywords A rct ic snow , chemical const ituent, enrichment factor , origin of hemical element.
