At the completion of this activity, the learner will be able to:

• Explain how the transition from conventional jet fuel to sustainable aviation fuels may change aircraft engine emission composition.

• Identify potential occupational exposure pathways to particulate matter and organic pollutants generated during aircraft engine operation.

• Describe the experimental approach used to evaluate emission characteristics and potential exposure implications for aviation workers.

Speaker: Onyinye Ezeifek, MSC

Onyinye Ezeifeka is a PhD Candidate in Environmental & Industrial Hygiene at the University of Cincinnati under the mentorship of Prof. Yevgen Nazarenko, where her research focuses on air quality assessment and occupational exposure to emissions from aviation turbine engines. Her work examines how the transition to sustainable aviation fuels may influence emission profiles and potential health risks for aviation workers. She conducts laboratory-based combustion experiments to characterize particle emissions and organic pollutants generated during aviation fuel combustion. Onyinye’s broader research interests include environmental pollutant control, exposure assessment, and indoor air quality management.
