Sorption-Desorption of Pyrene for Colombia and New Mexico Soils
Bibliographic record
Abstract
The adsorption and availability of polycyclic aromatic hydrocarbons (PAHs) in the environment is an important factor to be considered for potential bioremediation processes. If desorption of the organic occurs, it could imply that remediation technologies such as microbial degradation may be feasible for PAH contaminated soils. Conversely no, or partial, desorption would indicate that the components may persist in the environment due to their decreased bioavailability. The sorption-desorption of pyrene in conjunction with two different soils was studied to determine the feasibility of bioremediation as an effective treatment. The measured distribution coefficient (K d ) for the Colombia and New Mexico soils using a 4:40 soil:liquid ratio was 1956 and 526 L/kg, respectively. When the soil:liquid ratio was reduced to 1:40, the K d values were 4294 L/Kg for the Colombia, and 1141 L/Kg for the New Mexico soil.

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.
