EVALUACIÓN DE HIDROCARBUROS AROMÁTICOS POLICÍCLICOS EN SEDIMENTOS SUPERFICIALES DE LOS ESTEROS EL PAJAL Y CÁNDAMO DE LA BAHÍA DE TUMACO
Bibliographic record
Abstract
In the present study, the levels of sixteen polycyclic aromatic hydrocarbons (PAH) were determined in superficial sediments collected during three sampling campaigns carried out on May 2005, 14 months after oil spill, on December 2005 and on April 2006, in six stations at the tidelands. The Pajal and Candamo from Tumaco’s Bay, impacted by an oil spill occurred in March 2004. During the period of study the mean values of total PAH showed a decreasing trend, from 190ng/g obtained for the first campaign to 76ng/g for the last, letting to infer a temporal contamination and the area was in auto depuration state by product of petrogenic contamination processes. Finally, the concentrations for each of the PAH were found below the levels of risk established by the Canadian Environmental Quality Standards.

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.
