WebReactive mercury is more likely to be absorbed and methylated by bacteria than Hg 0, so reactive mercury poses the most direct health concern. Hg 0 may, however, be oxidized and converted to reactive mercury, so the two types are linked and must be considered together. WebMercury (Hg) exists in the atmosphere as three forms: gaseous elemental (GEM), gaseous oxidized (GOM), and particulate-bound (PBM). Often, GOM and PBM concentrations are combined and collectively described as reactive Hg (RM).
