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. 

 

There has been a global interest in evaluating toxicities, human exposure pathways, and mode of global transport of polyfluoroalkyl- and/or perfluoroalkyl substances (PFASs). The widespread environmental distribution of PFASs, especially perfluorooctanesulfonate (PFOS) and perfluorooctanoate (PFOA), makes these chemicals of emerging concern. These concerns over potential effects on the environment and human health of PFASs have led to several global research programmes on the understanding of PFAS’ sources, fate, transport, and toxicity. My research projects focus on these aspects and collaborate with other research groups to fill the knowledge gap for the missing pieces: 1) to understand pharmacokinetics and toxicology on PFASs using animal models; 2) to extend current knowledge of PFASs in developing countries; 3) to develop analytical method on measurement of PFASs and a new concept –mass balance approach- to understand current PFAS contamination in the environment using total organofluorine combustion ion chromatography (TOF-CIC); 4) to identify and measure newly identified PFASs in environmental samples using LC-ToF MS and LC-MS/MS spectrometry techniques; and 5) to study the fate and transport of unidentified PFASs in the environment. My research interests are not limited to PFASs, I also work with other research groups on different persistent organic pollutants (POPs) such as PAHs, PCBs, BFRs, and PCNs, pharmaceuticals as well as algal toxins.

 

 

I am also involved in teaching undergrad and grad courses at our department on analytical and environmental chemistry with focus on environmental forensics.
