Selenium in Ecosystems: Modeling Scenario Outcomes

Quantitative outcomes from applying ecosystem-scale selenium modeling to various environmental exposure scenarios. Hydrologic environment types include an estuary, reservoir, mainstream river, backwater, saline lake, and a wetland. Food webs illustrate invertebrates as prey and fish or birds as predators. Additional food-web steps can be added to illustrate more complex food webs (e.g., invertebrate through fish to bird or to include forage fish to predatory fish).
