Hg ∕ SO2
, Hg ∕ CO, and NOx
emission ratios (ERs) in the plume of the coal-fired power plant (CFPP), Lippendorf, near Leipzig in Germany, were determined in August 2013. GOM fraction of mercury emissions was also assessed. Measured Hg ∕ SO2
and Hg ∕ CO ERs were consistent with the ratios calculated from annual emissions in 2013 reported by the CFPP operator. The NOx
ER was somewhat lower. GOM fractions of ~ 40 % of CFPP mercury emissions in current emission inventories are overestimated.
