September 2019 – ICMGP Conference
This month my collaborators and I presented our research at the 14th International Conference on Mercury as a Global Pollutant.
Talks include:
- Testing methods for quantification and identification of reactive mercury compounds
- Development of an automated method for measurement of gaseous oxidized mercury
- Measurement and understanding GOM concentrations and chemistry from sites in Utah, Hawaii, Maryland, and Nevada, USA
- An integrated system for accurate, independently verified measurements of oxidized mercury
- Reactive mercury speciation and dry deposition during AMDEs in the Arctic
Posters include:
- Mercury is a global contaminant in commercial cat and dog foods
- Introducing UNRRMAS 2.0: Improvements for quantification and identification of atmospheric reactive mercury
- Ozone may not be an important oxidant of atmospheric mercury
