Study maps pollution’s pathway to the Arctic, sets path for future research

Thursday, September 13th, 2012

It’s been more than a decade since global leaders met in Stockholm, Sweden, to sign a treaty with the goal of eliminating persistent organic pollutants making their way into our food chain — such as harmful pesticides like DDT that nearly wiped out the American Bald Eagle. While leaders have come a long way in restricting these types of pollutants, contamination of the Arctic remains a problem. Researchers at MIT are working to help inform policies that more effectively address contamination problems with their latest research and the help of a new grant from the National Science Foundation.

“Persistent organic pollutants are chemicals of substantial international concern,” Noelle Selin, the project’s lead researcher and assistant professor in MIT’s Engineering Systems Division and Department of Earth, Atmospheric and Planetary Sciences, says. “For emerging contaminants in the Arctic, we need to know more about their sources, environmental behavior, and transport pathways in order to regulate them more effectively.”

Selin and Carey Friedman, a postdoctoral associate at the MIT Joint Program on the Science and Policy of Global Change, had their latest results published last week in the journal Environmental Science & Technology. The study, Long-Range Atmospheric Transport of Polycyclic Aromatic Hydrocarbons: A Global 3-D Model Analysis Including Evaluation of Arctic Sources, describes the researchers’ development of a detailed 3-D atmospheric model used to track the day-to-day transport of chemicals. Specifically, they tracked PAHs — toxic byproducts of burning wood, coal, oil and other forms of energy that remain in the atmosphere for less time than other persistent organic pollutants regulated by global standards.

The Changing Climate, Changing Health, Changing Stories – Riolet NL Canada

Friday, September 7th, 2012

The Changing Climate, Changing Health, Changing Stories project was a multi-year community-based capacity-building project situated in Rigolet, Nunatsiavut, Labrador. It was funded by Health Canada’s First Nations and Inuit Health Branch (FNIHB), with complementary funding from the Nasivvik Centre for Inuit Health and Changing Environments, from November 2009 – March 2011. The goal of our project was to study the impacts of climate change on human health and well-being in Inuit communities. It is now funded by the Rigolet Inuit Community Government. Specifically, this project utilized participatory community-based digital media, combined with qualitative methods such as interviews, focus groups and surveys, to gather data about climate-health relationships, while simultaneously creating accessible and transferable educational health media in the form of digital stories.

The overall goal of this project was to further develop individual and collective capacities in Rigolet to understand, identify, adapt to and manage health issues experienced in the community due to changes in climate using digital storytelling methodologies.

The Rigolet digital stories have been made available to the Arctic Health Website, both through the Rigolet site and via digital media that is not available on the site and which we plan to stream, allowing peoples throughout the arctic to have access.
