Mercury (Hg) emissions from domestic biomass combustion for space heating

► Three species mercury (Hg) were measured in lab, pilot plant, and field. ► GEM was the major Hg emitted from low temperature combustion. ► GOM was the major species released from a high temperature boiler stack. ► In the field, most GOM emitted from wood combustion was converted to PBM in winter. ► In the field, PBM was correlated with Delta-C implying wood combustion is a source in winter.
