Abstract
Polycyclic aromatic hydrocarbons(PAHs) residue in petroleum contaminated soils in Zhongyuan Oilfield was investigated.Results show that residue of PAHs in the soils ranged from 70.8 to 5 013.2 μg·kg-1 and was mainly composed of multi-ring(over 3 rings) PAHs,of which high concentration of benzo(a)pyrene(Bap) was detected in all the soil samples with the highest being 996.9 μg·kg-1,in the surface soils in front of the christmas trees.By referring to the standard Canada uses in controlling PAHs contamination in the soils of its agricultural zones,Nemerow composite index method was applied to the assessment of ecological risk of the contamination.Results show that the ecological risk of the soils around the wells,either in operation or recently closed,was quite high,and closely related to the working state and downtime of the wells and the distance from the christmas trees.The longer the downtime of a well,the lower the ecological risk of the soil around it,and the further to the well,the lower the risk.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
