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 behavior of mercury in the environment.

In its first stage, this work was dedicated to the development of the NOAA-HYSPLIT atmospheric deposition model. More recently, the focus 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.
