Hayley H. N. Hung, Ph.D., P.Eng.

Research Scientist - Trends and sources of organic pollutants in Arctic air

Current research and/or projects

Studies the long-term trends, sources and transport pathways of atmospheric organic contaminants to the Arctic

  • Leading the Northern Contaminants Program (NCP) project of "Northern Contaminants Air Monitoring: Organic Pollutant Measurements" and International Polar Year (IPY) project of "Intercontinental Atmospheric Transport of Anthropogenic Pollutants to the Arctic (INCATPA)"
  • Investigate the impact of climate change and variations on the movement of toxic organic contaminants to the Arctic
  • Study the long-term trends of organic pollutants in Arctic air to assess effectiveness and efficiency of national and international emission/ production/ usage control initiatives
  • Identify sources of organic contaminants to the Arctic and assess intercontinental transport of these pollutants
  • Development of air sampling strategies for organic chemicals in remote locations under extreme weather conditions and for new and emerging chemicals

Professional activities / interests

Member of the Arctic Monitoring and Assessment Programme (AMAP) Persistent Organic Pollutants (POPs) expert group

Collaborate internationally with atmospheric monitoring networks of organic pollutants in Norway, Iceland, Finland, U.S.A., Russia, Japan, China and Vietnam

Work with Professor Frank Wania and Ph.D. student Hang Xiao at the University of Toronto on the development, testing and deployment of a new flowthrough air sampler that does not require power supply or labour intensive maintenance during sampling, suitable for use in remote locations

Collaborate with Professor Brian McCarry and Ph.D. student Uwayemi Sofowote of McMaster University; and Professor Frank Wania and Ph.D. student John N. Westgate on the investigation of organic pollutant transport from the Pacific Rim to the Canadian Arctic
