Atmospheric Chemistry of Iron-Containing Aerosols

Fecha: 26/01/2024.
Hora: 13:00h.
Lugar: Sala de conferencias del IISTA. Online desde Google Meet.

Ponente: Professor Al-Abadleh is based in the Department of Chemistry and Biochemistry at Wilfrid Laurier University in Waterloo, Ontario, Canada. She is a Fellow of the Royal Society of Chemistry (UK) and at the Balsillie School of International Affairs in Waterloo. She is currently the Chair of the Atmosphere-Related Research in Canadian Universities (a special interests group with the Canadian Meteorological and Oceanographic Society). Professor Al-Abadleh was the 2019 Fulbright Canada Visiting Research Chair in Atmospheric Chemistry, Air Quality, and Climate Change at the University of California Irvine. Professor Al-Abadleh completed her PhD degree at the University of Iowa, USA (2003) followed by postdoctoral training at Northwestern University, USA (2005).

Resumen: During this seminar, Prof. Al-Abadleh will talk about the relevance of iron-containing aerosols in the atmosphere. Atmospheric aerosol effects on ecological and human health remain uncertain due to their highly complex and evolving nature while suspended in air. Atmospheric chemistry, global climate/oceanic and health exposure models need to incorporate more realistic representations of aerosol particles, especially their bulk and surface chemistry, to account for the evolution in aerosol physicochemical properties with time. (Photo)chemistry driven by iron (Fe) in atmospheric aerosol particles from natural and anthropogenic sources remains limited in these models, particularly under aerosol liquid water conditions. In this talk, results will be presented on (a) atmospheric aging of iron-containing dust and combustion fly ash due to reactions with phenolic compounds, (b) ice and cloud nucleation efficiency of fresh versus reacted dust particles and insoluble secondary organic aerosol from iron chemistry, (c) simulated human exposure experiments on the dissolution of Fe and other trace elements in dust. The significance of these results will be presented in relation to aerosol-radiation, aerosol-cloud interactions, and biogeochemical processes at the sea/ocean surface microlayer upon dust deposition.
