Bioaccumulation of Cadmium in Siam (Chromolaena odorata) and Node (Synedrella nodiflora) Weeds: Impact of Ethylene Diamine Tetraacetic Acid (EDTA) on Uptake
Bibliographic record
Abstract
The translocation and accumulation of Cd by Synedrella nodiflora and Chromolaena odorata plants growing in artificially Cd-contaminated soils amended with EDTA or without amendment had been studied to assess the phytoremediation potential of both species. Results showed that roots of S. nodiflora had the capacity of taking up a maximum 86.2 mg/kg of Cd from the contaminated soil while concentration in shoots amounts to a maximum 73.8 mg/kg. C. odorata was able to accumulate 42.8 mg/kg and 33.8 mg/kg in its roots and shoots respectively. The mobility of soil cadmium and the concentration of Cd in plants were both increased by EDTA amendment. EDTA application facilitated the translocation of Cd since the concentration in the roots and shoots of S. nodiflora increased to 104.9 mg Cd/kg and 77.0 mg Cd/kg respectively although the amendment effect was more pronounced on C. odorata increasing from 42.8 mg Cd/kg in roots from non-amended soils to 83.7 mg Cd/kg in the roots from amended soils. Despite the improved uptake by C. odorata, S. nodiflora appears to be more suitable for phytoremediation of Cd contaminated soils.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
