Particulate mercury emissions in regional wildfire plumes observed at the Mount Bachelor Observatory
Atmospheric mercury is composed primarily of Hg0 (>95%), but Hg+2 and particle bound mercury are also found in some environments. The three forms of mercury were measured at the Mount Bachelor Observatory beginning in 2005. Using data gathered from 2005 to 2007, 15 periods…
