Selenium in Ecosystems: Bay-Delta Ecosystem Scale Selenium Model
Detailed Description
The Bay-Delta Ecosystem-Scale Selenium Model illustrates five interconnected modules that depict essential aspects of the Bay-Delta's hydrology, biochemistry, and ecology and of the exposure and ecotoxicology of predators at risk from Se. These modules, and the detailed sub-models that also were developed, conceptualize and quantify (1) how Se is processed from water through diet to predators and (2) its effects on ecosystems. The outcomes of modeled scenarios also are given.

The San Francisco Bay-Delta receives selenium (Se) internally from oil refineries and externally through riverine agricultural discharges. Predator species considered at risk from Se consume the estuary’s dominant bivalve, C. amurensis, an efficient bioaccumulator of Se. Modeling predicts site-specific ecological risk and derives a range of protective Se concentrations for use by decision-makers.
