Analysis of Polychlorinated Dibenzo-P-Dioxins and Dibenzofurans in Pentachlorophenol Treated Poles
Bibliographic record
Abstract
Abstract The analysis of polychlorodibenzo-p-dioxins (PCDDs) and polychlorodibenzofurans (PCDFs) from pentachlorophenol (PCP) treated jack pine poles is described. The concentration of PCDD and PCDF was found to change dramatically with the age of poles. The older jack pine pole produced in 1956 was found to have a total PCDD/PCDF content of 15 μg/g in the 0–20 mm assay zone of its' ground-line, while a corresponding jack pine pole treated in 1979 contained up to 239 μg/g PCDD/PCDF in the same assay zone.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
