Selenium in Ecosystems: Ecosystem-Scale Model Methodology
Detailed Description
Ecosystem-scale selenium modeling conceptualizes processes and parameters important for quantifying and understanding the effects of selenium in the environment. The model can be applied to forecast exposure and to evaluate the implications of management or regulatory choices. Kd = empirically determined environmental partitioning factor between water and particulate material; TTF = biodynamic food-web transfer factor between an animal and its food.

Linking Selenium Sources to Ecosystems: Local and Global Perspectives
The sources, biogeochemistry, and ecotoxicology of selenium (Se) combine to produce a widespread potential for ecological risk such as deformities in birds and fish. Linking the understanding of source characteristics to a mechanistic, biodynamic dietary model of Se exposure on an ecosystem-scale improves the prediction of Se effects and its potential remediation.
Linking Selenium Sources to Ecosystems: Modeling
Selenium (Se) as a contaminant of ecosystems is bioaccumulative and causes reproductive effects in fish and wildlife. Ecosystem-scale Se modeling predicts Se bioaccumulation based on dietary biodynamics within site-specific food webs. The model can be used to forecast Se toxicity under different management or regulatory proposals or to translate a tissue guideline to a dissolved guideline.
