About William Hartz
Dr. William Hartz is an Environmental Chemist at the Man-Technology-Environment Research Centre (MTM) at Örebro University. He previously completed his PhD at the University of Oxford and University Centre in Svalbard, and also holds an external position at NILU in Norway.
Main research interests:
- Fate of contaminants in glaciers and Arctic environments, including a particular focus on per- and polyfluoroalkyl substances (PFAS)
- Mechanisms for long-range atmospheric transport of contaminants with a particular focus on polar environments
- Observations from snow and ice cores to understand pollution, climate and glacier dynamics
In recent years, his research has focused on the sources and processes of per- and polyfluoroalkyl substances (PFAS) in the snow and ice on Svalbard. This work has led to the discovery of new Arctic contaminants, observation of high seasonality in PFAS deposition in the Arctic and new understandings about the atmospheric sources of PFAS to the Arctic using an ice core as a record of historical atmospheric deposition. Additional work has also investigated the uptake and fate of PFAS in a marine food web influenced by local sources in the Arctic.
William is available for contact to discuss industry solutions and other projects for measuring PFAS/organofluorine contaminants in samples of all types.
