About Leo Yeung

Leo Yeung is an associate professor (docent) since June 2018. He joined the MTM Research Centre as a senior lecturer in 2016. He obtained B.Sc. (Environmental Life Science - 2003) at the University of Hong Kong, MPhil (Environmental Science - 2006) and PhD (Environmental Chemistry - 2009) at City University of Hong Kong; received post-doctoral training at City University of Hong Kong, National Institute of Advanced Industrial Science and Technology (Japan), and University of Toronto (Canada, 2010-2014). After that, he worked as a senior research associate at University of Toronto. 

 

Research

Leo Yeung’s research focuses on per- and polyfluoroalkyl substances (PFAS) and other persistent and mobile organic pollutants, with particular emphasis on total organofluorine and comprehensive analytical strategies for assessing known and unknown fluorinated contaminants. A central component of his work is the development of innovative mass-balance and approaches that move beyond traditional targeted analysis. By combining high-resolution mass spectrometry with total organic fluorine methodologies, his research enables identification of previously overlooked substances and improves understanding of environmental and human exposure.

  • His research includes:
  • Development of targeted and non-targeted PFAS methods
  • Mass-balance assessment of total fluorinated substances
  • Environmental occurrence and global transport of PFAS Human exposure and internal organofluorine burdens
  • Evaluation and verification of remediation and destruction technologies
  • Safe and sustainable chemical circulation

Beyond monitoring and identification, his work has a strong solutions-oriented focus. In collaboration with authorities, industry and international partners, he develops analytical frameworks to assess treatment efficiency, transformation pathways and fluorine mass balance.

Leo contributes to international standardisation and regulatory science, including ISO 21675 for PFAS in water, and serves as Co-Chair of the AOAC International Working Group on Total Organic Fluorine. He is also active in international PFAS and waste-management initiatives. His research is supported by competitive national and international funding and conducted together with doctoral and postdoctoral researchers.
