*Dr. Elsie Sunderland*, from the  U.S. Environmental Protection Agency 
National Center for Environmental Research, will be giving a seminar on 
Thursday September 14, as a part of the NOAA/ University of Michigan 
Great Lakes and Human Health Seminar Series.

Please find details of her talk listed below.

Title: Progress made in the development of a multi-compartment mercury 
model for the Great Lakes Region

Speaker: *Dr. Elsie Sunderland*, U.S. Environmental Protection Agency 
National Center for Environmental Research

Date: Thursday, September 14

Time: 1030 AM

Location: NOAA/ GLERL
             2205 Commonwealth Blvd., Ann Arbor, MI, 48105

Abstract
Over the past several years, the International Joint Commission, 
working  with the USEPA, NOAA and Environment Canada, and with several 
interested state and provincial parties, in particular the Ontario 
Ministry of the Environment has tracked and supported the development of 
models simulating the behaviour of mercury in the environment. The first 
stage of this work was dedicated to the development and verification of 
the NOAA-HYSPLIT atmospheric deposition model. The results of this work 
can be seen in the International Air Quality Advisory Board segments of 
the 1999/2001 and 2001/2003 Great Lakes Priority Reports available on 
the International Joint Commission website. More recently, the focus of 
this work has moved toward an attempt to develop a linked sequence of 
models to track the fate of mercury from its initial release into the 
larger environment and its substantial distribution into waterbodies, 
sediments, subsequent bioaccumulation and ultimate uptake by humans. 
Results from an initial application using the HYSPLIT atmospheric fate 
and transport model integrated with coupled environmental fate and 
food-web bioaccumulation models for Lake Ontario will be presented. 
Probabilistic human exposure modeling using the MENTOR modeling system 
will also be discussed. This talk will focus on an overview of some of 
the key areas of uncertainty in the relationships between mercury 
emissions, deposition and concentrations in the sediments, water, fish 
and human exposure highlighted by the application of each sub-model to 
Lake Ontario. Finally, information on mercury fate and transport in the 
Great Lakes Regions compiled by the IJC through a series of technical 
meeting will be reviewed and ongoing research, data collection efforts, 
and model improvements will be discussed.
