ARL to Participate in 13th International Conference on Mercury as a Global Pollutant
Symbol for the chemical element mercury.
ARL will be a highly visible and important presence at the 13th
International Conference on Mercury as a Global Pollutant (ICMGP2017) in
Providence, RI July 16-21, 2017. Mercury is a complex and multifaceted
contaminant that is a concern to human health and wildlife. The theme of
the conference is on understanding the multiple factors that accelerate
and attenuate recovery of mercury contamination in response to
environmental inputs on local to global scales. Nearly 1000 abstracts from
scientists in 57 countries have been received. NOAA ARL will be a Gold-
Level sponsor of the conference, alongside the U.S Forest Service, the
National Atmospheric Deposition Program, and the
National Institute for Minimata Disease (Japan).
ARL's Dr. Winston Luke will co-host (along with Dr. Mark Olson from
the National Atmospheric Deposition Program and Dr. Eric Prestbo from the Tekran Corporation)
a one-day workshop on "Best Practices for Measuring Atmospheric Mercury"
the day before the conference begins. The workshop will revisit and
discuss best practices to accurately measure mercury species in the
atmosphere using commonly-deployed monitoring equipment. The workshop will
serve two primary purposes:
The first is to discuss and revisit the Standard Operating
Protocols, promulgated after a 2008 gathering of mercury measurement
experts, for the operation of Tekran mercury speciation equipment
deployed throughout the National Atmospheric Deposition Program's
Atmospheric Mercury Network (AMNet). Discussions will center on lessons
learned and insights gained, with respect to data collection and data
reduction protocols, after nearly eight years of collective experience in deploying and operating network monitoring instrumentation.
The second purpose is to summarize and discuss recently-
documented artifacts in the measurement of Gaseous Elemental Mercury,
Gaseous Oxidized Mercury, and Particulate-Bound Mercury. Group
discussions will focus on identifying ambient conditions and
chemical/physical parameters associated with observed measurement
artifacts; attempts to bound the range of uncertainty in the measurement
of atmospheric mercury species; efforts to mitigate the measurement biases
and artifacts and/or to correct ambient data; and the current development of novel
measurement and calibration methodologies.
In addition to the workshop, Dr. Luke and three other ARL scientists will each present their mercury
research at the Conference.
Dr. Xinrong Ren will discuss measurements at the ARL-Grand
Bay National Estuarine Research Reserve AMNet site in a
presentation entitled "Long-term Monitoring of Mercury
Speciation at a Coastal Site in the Northern Gulf of Mexico."
Dr. Mark Cohen will discuss variations in simulation results
using differing modeling frameworks in his presentation
"Comparison of Lagrangian, Eulerian, and Hybrid
Mr. Paul Kelley will discuss ARL's
latest research to understand and evaluate the often-subtle
sources of measurement accuracy degradation in network
operations in his presentation entitled "Development and Testing
of a GEM Standard Addition System to a Speciated Mercury
Dr. Winston Luke will provide a summary and analysis
of the long-term data record of atmospheric mercury at the Mauna
Loa Observatory in his presentation entitled "Speciated
Atmospheric Mercury Measurements at the Mauna Loa, Hawaii AMNet Site: Patterns, Trends, and Sources."
