Short-term exposure to wildfire-related PM2.5 increases mortality risks and burdens in Brazil

Nature Communications, 2022
To assess mortality risks and burdens associated with short-term exposure to wildfire-related PM2.5, the authors collect daily mortality data from 2000 to 2016 for 510 immediate regions in Brazil, the most wildfire-prone area.

Contributions of natural and anthropogenic sources to ambient ammonia in the Athabasca Oil Sands and north-western Canada [PDF]

Atmospheric Chemistry and Physics, 2018
Atmospheric ammonia (NH3) is a short-lived pollutant that plays an important role in aerosol chemistry and nitrogen deposition. Dominant NH3 emissions are from agriculture and forest fires, both of which are increasing globally.

Inverse modelling of carbonyl sulfide: implementation, evaluation and implications for the global budget [PDF]

Atmospheric Chemistry and Physics, 2021
Carbonyl sulfide (COS) has the potential to be used as a climate diagnostic due to its close coupling to the biospheric uptake of CO2 and its role in the formation of stratospheric aerosol.

Use of Association Algorithms in Air Quality Monitoring

, 2023
Over the years, there has been a gradual increase in the emission of pollutants, and it is imperative to establish mechanisms to monitor air quality. In addition to carbon dioxide (CO2), particulate matter (PM) is considered one of the main types of air ...

Wildfire-related PM2.5 and health economic loss of mortality in Brazil

Environment International, 2023
Background: Wildfire imposes a high mortality burden on Brazil. However, there is a limited assessment of the health economic losses attributable to wildfire-related fine particulate matter (PM2.5).

Constraints and biases in a tropospheric two-box model of OH [PDF]

Atmospheric Chemistry and Physics, 2019
The hydroxyl radical (OH) is the main atmospheric oxidant and the primary sink of the greenhouse gas CH4. In an attempt to constrain atmospheric levels of OH, two recent studies combined a tropospheric two-box model with hemispheric-mean observations of ...
