Phoshpine (PH3), a volatile and toxic gas, has been proved to commonly exist in the environment. The determination of gaseous phosphine and its emission fluxes in Ny-Alesund is reported in this paper. Results showed that gaseous phosphine exist in Arctic atmosphere commonly and the concentration of phosphine ranged from 16.3-600.2 ng/m(3), with the maximum concentration of phosphine in tundra areas and the minimum in surface air of ocean. The concentration of phosphine ranged from 65.79-1259 ng/m(3) in colliery atmosphere at different altitudes and the maximum was found in the center of colliery. Emission fluxes of phosphine were different in various Arctic areas. Emission fluxes of phosphine from protected areas, with average concentration of 2.13 +/- 5.353 ng m(-2) h(-1), were higher than from other areas. And the flux of phosphine from ocean was lower.
