What comes out from forest fire? An in-depth analysis of gaseous and particulate emissions from biomass burning on “Metaponto Natural Reserve”

Enrica Nestola (IRET-CNR)

Combustion tests have been performed on the biomass sampled in Metaponto National Reserve (Basilicata Region, South of Italy). The aim was the characterization of gaseous and particulate emissions from the combustion of different plant species.

Biomass was burned into a combustion chamber, which continuously quantifies emissions throughout the different phases of a fire. Controlled conditions allowed the characterization of the emission factors for different biomass types and properties. 

As largely known, particulate matter (PM) is highly detrimental to human health, also depending on its chemical composition, and is one of the most significant emissions from forest fire. Furthermore, the finer is the PM the more dangerous is for health.  For these reasons, PM was characterized both for the dimensional (PM1, PM2.5, PM10) and chemical composition, related to different tree species. Through this approach a PM emission profile of important forest species, such as Pinus sp. and Eucalyptus sp., has been created.

Parametrization of the emissions coming from different plant type provides important information relevant to modelers and for the improvement of fire management.
