Resumo
This research aims to assess air quality in a transitional location between city and forest in the Amazon region.
Located downwind of the Manaus metropolitan region, this study is part of the large-scale experiment
GoAmazon2014/5. Based on their pollutant potential, inhalable particulate matter (PM2.5), nitrogen dioxide
(NO2), sulfur dioxide (SO2), ozone (O3), hydrogen sulfide (H2S), benzene, toluene, ethylbenzene and meta-,
orto-, para-xylene (BTEX) were selected for analysis. Sampling took place during the wet season (March–April
2014) and dry season (August–October 2014). The number of forest fires in the surroundings was higher during
the dry wet season. Results show significant increase during the dry season in mass concentration (wet:
b0.01–10 μg m−3 ; dry: 9.8–69 μg m−3 ), NH4
+ soluble content (wet: 13–125 μg m−3 ; dry: 86–323 μg m−3 )
and K+ soluble content (wet: 11–168 μg m−3 ; dry 60–356 μg m−3 ) of the PM2.5, and O3 levels (wet: 1.4–14
μg m−3 ; dry: 1.0–40 μg m−3 ), indicating influence of biomass burning emissions. BTEX concentrations were lowin both periods, but also increased during the dry season. Aweak correlation in the time series of the organic
and inorganic gaseous pollutants indicates a combination of different sources in both seasons and NO2 results
suggest a spatial heterogeneity in gaseous pollutants levels beyond initial expectations.
