Arsenic hyperaccumulation by different fern species
Open accessAbstract
Summary: Pteris vittata was the first identified arsenic (As) hyperaccumulator. Our aim was to test whether As hyperaccumulation occurs in other fern species, and whether P. vittata collected from both contaminated and uncontaminated environments accumulates As similarly. Three accessions of P. vittata , two cultivars of Pteris cretica , Pteris longifolia and Pteris umbrosa were grown with 0–500 mg As kg −1 added to the substrate. A second experiment compared As uptake by five common ferns obtained from commercial suppliers. The results show that, in addition to P. vittata , P. cretica , P. longifolia and P. umbrosa also hyperaccumulate As to a similar extent. There was little difference between different Pteris species, or between different accessions of P. vittata . By contrast, Asplenium nidus , Davallia canarensis , Polypodium aureum , Polystichum tsus‐simense do not hyperaccumulate As. This study identified three new species of As hyperaccumulators in the Pteris genus and suggests that As hyperaccumulation is a constitutive property in P. vittata .

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.
