Hourly averaged gaseous elemental Hg (GEM) concentrations and hourly integrated reactive gaseous Hg (RGM), and particulate Hg (HgP) concentrations in the ambient air were measured at Huntington Forest in the Adirondacks, New York from June 2006 to May 2007. The average concentrations of GEM, RGM, and HgP were 1.4 ( 0.4 ng m-3, 1.8 ( 2.2 pg m-3, and 3.2 ( 3.7 pg m-3, respectively. RGM represents
