Chemical characterisation of biomass burning smoke particles using Electrospray-Orbitrap mass spectrometry

Australian bushfires and prescribed biomass burning (BB) have a significant impact on both human health as well as global and regional climate.While emissions from traditional sources, such as vehicles and power plants are expected to decline due to more stringent regulations, air pollution from BB smoke is expected to continue growing.The impact of BB smoke particulate matter on human health will depend on their chemical and physical properties. However, that information for smoke from Australian ecosystems is very limited.The aim …

Precursors of atmospheric aerosols in the Southern Ocean and Antarctica

Atmospheric aerosols are tiny liquid or solid particles suspended in air. They have a significant role in the radiative balance through their direct interaction with incoming solar radiation (scattering and absorption), and indirectly through their interactions with cloud (they act as seeds on which water can condense to form clouds).Indirect effect is a much more complex problem, and involves the role of aerosols in the cloud formation and the modification of their properties such as changes to cloud reflectivity, cloud …

Laboratory simulation of Secondary Organic Aerosol (SOA) formation

This project aims to investigate the interaction of anthropogenic (human-made) emissions and biogenic emissions from plants and trees and subsequent secondary organic aerosol (SOA) production in urban environments. This is relevant as SOA is part of particulate matter (PM), which is associated with smog events in cities, affects the climate and has negative impacts on human health.SOA is formed in the atmosphere by complex reactions of volatile organic compounds (VOCs) of anthropogenic or biogenic origin with atmospheric oxidants (OH radicals, …
