A number of factors are known to affect the degree of oxidation of elemental mercury. The major ones include halogen content (e.g. Cl, Br), temperature, reductants (e.g. NH3 and SO2), catalyst chemistry and catalyst age, as well as flue gas constituents e.g. Hg, H2O.
Halogen content in the fuel and flue gas is an important driver for achieving mercury oxidation through the SCR catalyst. Chlorine levels in some bituminous coals exceed 500 ppmw, resulting in HCl levels in the flue gas of greater than 35 ppm, so helping to drive greater formation of oxidized mercury via...

If the demonstrations have gained momentum in part due to economic hardship and especially disillusionment with the political elite, they were initially triggered por a highly controversial mining project and the ecological and cultural damage that it might cause.

Though environmental issues have for a long time been seen as marginal in Southeastern European politics, it would not be the first time that environmental protests have snowballed into anti-establishment movements in the region....World Politics Review
