Quantitative assessment of upstream source influences on total gaseous mercury observations in Ontario, Canada
upstream source total gaseous mercury Ontario, Canada
2011/2/25
Hourly total gaseous mercury (TGM) concentrations at three monitoring sites (receptors) in Ontario were predicted for four selected periods at different seasons in 2002 using the Stochastic Time-Inver...
Global atmospheric model for mercury including oxidation by bromine atoms
Global atmospheric model mercury oxidation bromine atoms
2010/12/28
Global models of atmospheric mercury generally assume that gas-phase OH and ozone are the main oxidants converting Hg0 to HgII and thus driving mercury deposition to ecosystems. However, thermodynamic...
