The fate of mercury species in a sub-arctic snowpack during snowmelt
received 12 MArch 2003;revised 1 may 2003; accepted 15 May 2003 An extensive mercury study was conducted in April 2002 prior to and during the annual melting of a snowpack in a sub-arctic site along the Hudson Bay (Canada). Gas-phase measurements show that the snowmelt coincides with an elemental me...
