abstract = "Mercury stored in forests can be volatilized to the atmosphere
during fires. Many factors influence this process such as mercury
concentration, vegetation loading and the soil temperature reached
during the fire. We quantified mercury emissions from biomass and
soil during a prescribed fire in Brazil using the difference in
mercury burden in vegetation and soil before and after burning,
and data were critically compared with those previously obtained
in a similar experiment in another part of the Amazonia. The
calculated mercury emission factor was 4.1±1.4gHgha-1, with the
main part (78%) originating from litterfall and O-horizon, and
only 14% associated with live biomass. When considering the fuel
burned loading, the emission factor ranged from 40 to 53¼gHgkg-1.
Data were also obtained on soil temperature profile and on Hg
speciation in soil in an effort to relate these parameters to Hg
emissions.",
