curriculum vitae

Christian Bogdal is a senior scientist in environmental chemistry in the Safety and Environmental Technology Group at the Swiss Federal Institute of Technology Zurich (ETH Zurich) and in the Trace Organic Analytical Chemistry Group at the Swiss Federal Research Station Agroscope (Agroscope).

In 2014, he was visiting researcher in the Department of Environmental Science and Analytical Chemistry at Stockholm University (ACES).

He earned his doctoral degree in chemistry from ETH Zurich in 2008. In his doctoral thesis, he combined trace analysis with multimedia modeling to investigate the environmental fate of persistent organic pollutants. He did his thesis at the Swiss Federal Laboratories for Materials Testing and Research (Empa) under supervison of Prof. Konrad Hungerbühler from ETH Zurich.

He received his master degree in environmental sciences from the Swiss Federal Institute of Technology Lausanne (EPFL) in 2005. He did his master thesis at the University of Illinois at Urbana-Champaign (UIUC).

Research Group and Projects

Christian Bogdal is supervising several doctoral students in the field of environmental chemistry. The following projects are carried out in his research group.

- Melting glaciers as a secondary source of persistent organic pollutants (POPs) (GlazioPOP, doctoral theses of Pavlina A. Pavlova and Christine Steinlin).
- Primary emissions and fate of POPs and other persistent chemicals in urban areas (CityPOP, doctoral thesis of Pascal S. Diefenbacher).
- Emissions, fate, and mass balance of POPs in Switzerland (SwissPOP, doctoral thesis of Juliane Glüge)
- Long-range transport and source apportionment of atmospheric mercury (SwissQuick, doctoral thesis of Basil Denzler).
- Environmental fate of brominated flame retardants and other persistent organic pollutants in aqueous ecosystems (BFRs).

Research Interests

- Environmental fate of persistent organic chemicals and mercury, including sources and sinks of chemicals, transport pathways and transformation processes.
- Temporal trends of persistent chemicals and mercury in the environment.
- Identification and quantification of primary and secondary sources of persistent organic pollutants and mercury in the environment.

Investigated compound classes include persistent organic pollutants such as polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), polychlorinated biphenyls (PCBs), as well as organochlorine pesticides. Next to these legacy pollutants, chlorinated paraffins (polychlorinated n-alcanes) are also a main focus of research. Additionally, contemporary compounds, including brominated flame retardants and synthetic musk compounds, are also studied. Recently, a significant part of the research has been dedicated to mercury compounds.

Analytical chemistry tools for the analysis of field samples are combined with multimedia models. The laboratory analysis of organic compounds are based on gas chromatography (GC) coupled to high-resolution mass spectrometry (HRMS). Mercury is analyzed with fluorescence spectroscopy. The developed models are fugacity based multicompartmental fate models.

Several topics for a master thesis are possible and can be discussed. Interested students are invited to contact Christian Bogdal (Master Thesis).
