Short summary
This paper quantifies the emissions of mercury from biomass burning in Canada. Using an emissions inventory of mercury in the GEM-MACH-Hg model, surface observations of mercury concentration, and a top-down inversion method, we generate optimized emissions of mercury. We find that biomass burning is an important source of mercury emissions and deposition in Canada. Significant uncertainty remains, due to uncertainty in the speciation of emitted mercury.
