Influence of Catclaw<i>Mimosa Monancistra</i>on the Dissipation of Soil PAHS
Bibliographic record
Abstract
Phytoremediation is a cost-effective biotechnology for decontamination of polycyclic aromatic hydrocarbons (PAHs)-polluted soils. A greenhouse experiment was conducted to determine the growth of Mimosa monancistra, a N2-fixing leguminous plants, and its capacity to remove phenanthrene, anthracene, and benzo(a)pyrene (BaP)from soil. The PAHs decreased shoot and root dry biomass of M. monancistra 2.7- and 3.9-fold, respectively, compared to uncontaminated soil and inhibited nodule formation. The removal of phenanthrene and anthracene was similar in vegetated and unvegetated soil, but the dissipation of BaP was significantly faster in vegetated soil as compared to unvegetated soil after 14, 56, 70, and 90 d. After 90 d, dissipation of BaP was 96% in vegetated soil and 87% in unvegetated soil. Nitrification and ammonification were not affected by the addition of PAHs as concentrations of NH4+, NO2-, and NO3- were similar in contaminated and uncontaminated vegetated soil. Growth of M. monancistra was inhibited by contamination with hydrocarbons, but removal of BaP was accelerated in the rhizosphere.

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.
