Deposition of trace elements in the Trail region, British Columbia; an assessment of the environmental effect of a base metal smelter on land
Bibliographic record
Abstract
This study was carried out to assess the spatial deposition and accumulation of trace elements on surface soil in the Trail area, British Columbia, site of a base metal smelter. Monitoring of the deposition was performed by strategically placing twenty-two flat moss-bags (moss-monitoring stations), in the study area and allowing them to be exposed to aerial deposition for 3-month periods over the course of the two-year study. The main goal of this research was to determine the cumulative deposition of the "settleable" portion of elements on land, the extent of influence from the point source, and the seasonal variations in the deposition pattern. The results of this study give a better understanding of the net increase of trace elements in surface soil over a given period of time. This is important in terms of the calculation of the element inventory of the soil and for long-term prediction of the future amounts of trace elements.

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.
