Due to its sorption with soil, lead is not readily accessible in biological systems and has limited solubility at normal pH, making it unavailable for plant absorption even by hyperaccumulators.
“Due to its sorption with soil, lead is not readily accessible in biological systems and has a limited solubility at normal pH, making it unavailable for plant absorption even by hyperaccumulators (Chen et al., 2004; Bahraminia et al., 2016).”
From Plant hyperaccumulators: a state-of-the-art review on mechanism of heavy metal transport and sequestration (2025) · cites this paper as Chen et al., 2004
The Introduction describes soil-bound Pb being mobilized by EDTA, and the Discussion describes soil adsorption and low Pb uptake by vetiver shoots under normal soil conditions (pages unavailable). These passages support limited accessibility, but not the claim that Pb is unavailable for absorption even by hyperaccumulators: the Discussion reports measurable uptake by vetiver and other plants. The copy also does not establish a specific solubility limit at normal pH. (LLM, conf=0.86)

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.
