Driscoll to Co-Chair International Mercury Conference
Professor Charles Driscoll will co-chair the 13th International Conference on Mercury as a Global Pollutant (ICMGP 2017) in Providence, Rhode Island, with fellow mercury scientist Celia Chen from Dartmouth College. The conference, running July 16-21, aims to share science, reduce exposure and develop measures to decrease atmospheric emissions and discharges of the poisonous metal.
With the theme of integrating mercury research and policy in a changing world, this year’s conference comes one month before entry into force of the Minamata Convention on Mercury. The global treaty requires countries to control new and existing mercury sources and to monitor the effectiveness of those controls.
“Mercury is a widespread global pollutant with impacts on human health largely through fish consumption,” says Chen, mercury project leader of the Dartmouth Toxic Metals Superfund Research Program. “Human activity is an important cause of mercury pollution and human health suffers because of it, so it is important to have scientific study, innovative management strategies and cooperation among all nations to reduce the negative impacts of mercury.”
Mercury is a complex contaminant and a known neurotoxin for humans and wildlife. Methylmercury, the more toxic form of the metal, increases in concentration as it travels up the food chain and is the cause of most mercury-related fish consumption advisories and wildlife impacts.
Mercury transport, transformations, bioaccumulation and exposure are affected by climate change, nutrient loading, land use, food web dynamics, human behavior and decision making. Concentrations of mercury in the environment have increased in the last century largely due to human activities such as coal combustion, chemical manufacturing and mining.
In the U.S., the implementation of the Mercury and Air Toxics Rule limits power plant emissions of mercury and other toxic air pollutants. In many countries, the use of mercury in artisanal gold mining is under investigation as the magnitude of associated mercury releases and effects have been underestimated.
Under the ICMGP 2017 theme, the conference will improve understanding of the complex factors that accelerate and reduce recovery from mercury contamination at local to global scales.
“We have made considerable progress in mercury regulations to control the release of this toxic metal, and efforts are underway at the local level to remediate mercury contaminated sites,” says Driscoll, University Professor of Environmental Systems and Distinguished Professor in the College of Engineering and Computer Science. “At the same time, uncertainty remains over the levels of exposure linked to a range of effects of mercury on wildlife and human health. While these initiatives are important steps to mitigate mercury contamination, the extent and rate of recovery is unclear due to uncertainties in our understanding of mercury transport, cycling and trophic transfer and under changing climate.”
The ICMGP Executive Committee is responsible for the organization of the conference and is comprised of: David Gay, University of Illinois; Betsy Henry, Anchor QEA; Robert Mason, University of Connecticut; Noelle Selin, Massachusetts Institute of Technology; Kimberley Driscoll, Syracuse University; and Marcella Thompson, University of Rhode Island.
