Changing Aviation Fuel Chemistry: Implications for Occupational Exposure to Engine Emissions

About the webinar:

This presentation introduces emerging industrial hygiene questions related to the transition from conventional jet fuel to sustainable aviation fuels. It discusses how changes in fuel chemistry may alter aircraft engine emission profiles and potential worker exposures to particulate matter and organic pollutants. Learners will explore motivation, experimental approaches, and planned research to assess exposure implications for aviation workers.

Learning Objectives

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 EZEIFEKA, 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.

ACCREDITATION

The Center for Occupational and Environmental Health designates this activity for a maximum of 1.0 Contact Hour. Participants should claim only the credit commensurate with the extent of their participation.
