“…These states, as well, held the largest number of outbreaks of fire during the study period. Further research [11][12][13][14] found similar occurrences with fire burning in Asia and an association with an increase in hospitalizations for asthma and other respiratory illnesses. Though, higher rates in the period may be explained by the decrease in relative humidity during this season and the consequent increase in the amplitude between maximum and minimum temperatures 27 .…”

“…In 2007, the Amazon reported admissions in the elderly population totaling 157 055 in the SUS, with asthma accounting for 3 554 (2.3%) 8 . Specific studies on forest burning in Asia have shown an increased incidence of asthma and acute respiratory infections (ARI) [11][12][13][14] in those areas. Studies in the Southeast have also shown an increasing trend in hospitalizations for asthma and other respiratory diseases related to biomass burning in urban areas [15][16][17][18] , with a greater frequency of hospitalization for respiratory diseases in the dry season for various age groups [19][20] .…”

Introduction: In Brazil, there are approximately 370,000 asthma-related hospitalizations per year, representing the fourth leading cause of hospitalizations in public health services. In 2007, 157,000 elderly patients were hospitalized, 2.3% of which due to asthma in the Brazilian Amazon. The rate of hospitalizations during the dry season was as much as three times that of the rain and intermediate seasons, with the highest rates in Rondônia (5.8 ‰) and Mato Grosso (3.3 ‰). Conclusion: Asthmarelated hospital admissions in the elderly presented a declining trend and a significant seasonal variation, with the highest rate of hospitalizations observed during the dry season.

“…According to Muraleedharan et al (2000a) many Southeast Asian haze episodes, such as those recorded in 1983, 1990, 1991, 1994, 1997 and 1998, have resulted in negative health effects on a large population. Suspended particles from haze in particular can impact human health in a number of ways, leading to conditions such as upper respiratory tract infection, asthma, and conjunctivitis (Awang et al, 2000). In addition, the release of organic pollutants from biomass burning, such as PAH which is carcinogenic, can lead to a high risk of cancer (Tullin et al, 2001;Silva et al, 2010).…”

While peatland has long been exploited for agricultural activities, these make it vulnerable to fires, which emit pollutants into the atmosphere and adversely affect air quality. The aim of this study was thus to determine the main composition of air pollutants from peat soil combustion. The main parameters of the related gas pollutants, e.g., SO 2 , NO 2 , CO, O 3 and PM 10 , and their components, such as anions, cations, heavy metals and levoglucosan, have been determined. The gas concentration was determined using the colorimetric method after the air had been assimilated into absorbing solutions. The PM 10 concentration was established using a low volume air sampler equipped with weighted filter paper. The anion concentration of PM 10 was analyzed using ion chromatography, while the cation and heavy metal concentrations were ascertained using inductively couple plasma-mass spectroscopy (ICP-MS). Moreover, the concentration of levoglucosan was determined using the Anthrone-Sulfuric Colorimetric method. The results show that the dominant gas from the emission of burning peat soil was CO (13850-20610 μg/
