Acceleration of selenium volatilization in seleniferous agricultural drainage sediments amended with methionine and casein

Bañuelos, G.S., Lin, Z.-Q.·2007·Environmental Pollution

Abstract

Phytoremediation is potentially effective for managing excessive selenium (Se) in drainage sediment residing in the San Luis Drain in central California. This 2-year field study examined the feasibility of amending drainage sediment (containing 4.78microgSeg(-1)) with methionine and casein to enhance volatilization without or with vegetation of Sporobolus airoides. Results show that without organic amendments, rates of Se volatilization were less than 25microgm(-2)d(-1) in all plots. After amending the sediment with 71.4mgmethioninekg(-1) soil, Se volatilization rates were 434+/-107microgm(-2)d(-1) in vegetated plots and 289+/-117microgm(-2)d(-1) in irrigated bare plots. With the amendment of 572mgcaseinkg(-1) soil, rates increased to 346+/-103microgm(-2)d(-1) in irrigated bare plots and to 114+/-55microgm(-2)d(-1) in vegetated plots. Both methionine and casein promoted biological remediation of Se via volatilization most effectively during the warmest months.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Genetic engineering for higher selenium levels in plants has been reviewed and applied to Brassica crops in field conditions.

    “Genetic engineering for the promotion of higher Se levels in plant has been reviewed earlier by others [34,35] and applied to Brassica crops in field conditions [36,37].”
  • The majority of information on the pathways of Se methylation is based on research conducted with (Se-tolerant) plants and has been extensively reviewed.

    “The majority of information on the pathways of Se methylation is based on research conducted with (Se-tolerant) plants [36,37] and has been extensively reviewed [49,55].”
  • The biogenic production of volatile Se compounds and the corresponding Se emissions have been assessed in a variety of environmental compartments including soils and sediments, plant leaves, peat bogs, estuarine waters, lakes, and the marine environment.

    “Although quantitative measurements are relatively scarce, the biogenic production of volatile Se compounds and the corresponding Se emissions have been assessed in a variety of environmental compartments including soils and sediments [37,262,263,264,265,266,267], plant leaves [268], peat bogs [95,261], estuarine waters [268], lakes [269] and in the marine environment [92,96].”

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.
