Selenium Removal by Constructed Wetlands: Role of Biological Volatilization
Open accessAbstract
Selenium-laden effluents from oil refineries are polluting San Francisco Bay, California. One environmentally friendly way of cleaning up selenium (Se) from effluents is by plant and microbial Se volatilization using constructed wetlands. Using mesocosms, we investigated the role of biological Se volatilization in a 36-ha constructed wetland located adjacent to San Francisco Bay. The constructed wetland was highly effective in removing Se from selenite-contaminated oil refinery wastewater: 89% of the Se was removed. Inflow Se concentrations of 20−30 μg L - 1 decreased to <5 μg L - 1 in the outflow. Most of the Se was removed by immobilization into sediments and plant tissues where Se concentrations reached ∼5 and ∼15 mg kg - 1, respectively. Biological volatilization may have accounted for as much as 10−30% of the Se removed. The highest mean rates of Se volatilization for vegetated sites were 190, 180, and 150 μg of Se m - 2 day - 1 (rabbitfoot grass, cattail, and saltmarsh bulrush, respectively). Rates for the most dominant species, saltmarsh bulrush, varied during the year: the mean rates were 150, 70, and 25 μg of Se m - 2 day - 1 in February, June, and October, respectively. We conclude that biological Se volatilization is a significant pathway of Se removal in wetlands.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
