Typically reads between 2 to 3 micrograms/m^3
Typical concentrations are between 2-3 micrograms per cubic meter. I have seen several sites that burn the same PRB coal that often have double these concentrations.
This is unit 2 Hg readings with a normalized load plot in Megawatts. Note the correlation to load vs. MW.
