Oxidative potential of fine particle emissions of a residential wood-fired boiler
Biomass types with high combustion-emitted PM emissions did not necessarily exhibit high oxidative potential (OP), highlighting the role of particle chemical compositions in influencing OP and potential impacts.
Paper
SO2 and NOx emissions from ships in North-East Atlantic waters: in situ measurements and comparison with an emission model
Measurements of apparent fuel sulfur content (aFSC) of ship plumes showed a 10-fold decrease between 2019 and 2021, demonstrating the strong impact the International Maritime Organization regulation change in 2020 had on sulfur emissions from ships.
Paper
Variations in oxygenated and nitrogen-containing primary organic compounds based on the fuel type and burning condition in stove emissions
Differences in primary aerosol composition exist between peat, leaves and wood fuels, while the effect of burning conditions is only noticeable due to the changes in AMS f60. CHO compounds are more abundant but show lesser aromaticity than the CHON.
Paper
Evaluating the variability and consistency of NOx emission regulation between sectors
Most UK emissions regulations are sector and appliance specific and reported based on activity data. Here we assess key NOx emitting sectors using a unified metric: grams of NOx per kilowatt hour (g[NOx] kWh−1).
About this collection
This collection brings together recent advances in understanding combustion emissions and their impacts on atmospheric chemistry, air quality, climate, and health. The articles examine emissions of key pollutants (including sulphur and nitrogen oxides, volatile and oxygenated organic compounds, and fine particulate matter) from a range of combustion sources, alongside their atmospheric transformation into secondary species. Contributions highlight implications for particulate matter composition, oxidative potential, and climate forcing, as well as associated health effects. Together, this work provides valuable insights to support more effective mitigation and management of combustion-related pollution in a changing environment.
