BOULANGER, B. AND K. HORNBUCKLE. FLUORINATED SURFACTANTS IN THE GREAT LAKES - YESTERDAY, TODAY, AND TOMORROW. Presented at International Joint Commission - New Chemicals Workshop, Kingston, ON, CANADA, June 09, 2005.
Impact/Purpose:
The presentation will focus on the work performed by the University of Iowa on the Great Lakes in 2004. The discussion will be on the annual lake-wide mass budget data of eight perfluorooctane surfactants for Lake Ontario.
Description:
Perfluorooctane surfactants have been reported in biota, water, and air samples worldwide. Despite these reports, the main environmental sources of these compounds remain undefined. As a presentation to the emerging chemicals workshop of the International Joint Commission on Great Lakes research, this talk is focused on work performed by the University of Iowa on the Great Lakes in 2004. An annual lake-wide mass budget of eight perfluorooctane surfactants for Lake Ontario is discussed. The mass budget finds inflow from Lake Erie and wastewater discharge to the lake to be the major sources, while outflow through the St. Lawrence River is the dominant loss mechanism. Atmospheric contributions and losses from the lake are negligible. Using the mass budget data and data from other researchers, a temporal evaluation of fluorinated surfactants in the lake is presented.
