Global Hg and US Exposures

Global Mercury Emissions and U.S. Population Exposures

 

PI: Elsie M. Sunderland

PEOPLE: Bess Corbitt, Asif Qureshi

SUPPORT: U.S. EPA

 

Greater than 90% of population wide exposure to mercury in the U.S. is from estuarine and marine fish and over 75% of these fish are harvested in open ocean regions. This project is combing our research modeling various elements of the global biogeochemical mercury cycle to estimate potential changes in US population exposures with changes in global anthropogenic emissions, which will help inform the 2013 Global Mercury Treaty Process being negotiated by UNEP.
