abstract = "The rate of deforestation in Brazil increased by 29% between 2015
and 2016, resulting in an increase of greenhouse gas emissions
(GHG) of 9%. Deforestation fires in the Amazonia are the main
source of GHG in Brazil. In this work, amounts of CO 2 , CO, main
hydrocarbon gases and PM 2.5 emitted during deforestation fires,
under real conditions directly in Brazilian Amazonia, were
determined. A brief discussion of the relationship between the
annual emission of CO 2 equivalent (CO 2,eq ) and Paris Agreement
was conducted. Experimental fires were carried out in Western
Amazonia (Candeias do Jamari, Rio Branco and Cruzeiro do Sul) and
results were compared with a previous fire carried out in Eastern
Amazonia (Alta Floresta). The average total fresh biomass on the
ground before burning and the total biomass consumption were
estimated to be 591 ton ha \−1 and 33%, respectively. CO 2
, CO, CH 4 , and nonmethane hydrocarbon (NMHC) average emission
factors, for the four sites, were 1568, 140, 8, and 3 g kg
\−1 of burned dry biomass, respectively. PM 2.5 showed
large variation among the sites (0.916 g kg \−1 ).
Emissions per hectare of forest were estimated as 216,696 kg of CO
2 , 18,979 kg of CO, 1,058 kg of CH 4 , and 496 kg of NMHC. The
average annual emission of equivalent CO 2 was estimated as 301 ±
53 Mt year \−1 for the Brazilian Amazonia forest. From
2013, the estimated CO 2,eq showed a trend to increase in Amazon
region. The present study is an alert and provides important
information that can be used in the development of the public
policies to control emissions and deforestation in the Brazilian
Amazonia.",
