Environmental and Human Health Risk Assessment for Essential Trace Elements: Considering the Role for Geoscience
Bibliographic record
Abstract
In environmental and human health protection, the role for geoscience may be expressed by how it enhances certainty in the hazard potential models that support risk assessment. For geochemical hazards, certainty reflects how well geoscience simplifies variability in the element concentrations and in the environmental conditions associated with exposure pathways. Through mineralogy, geoscience establishes natural geochemical background variability in terms of provenance, process, and past, and it links hazard potential to the physical and chemical transformation due to weathering and soil formation. The interpretation of hazard potential may be expressed by how analytical protocol, expressed by grain size and strength of acid decomposition, combines with geological factors, expressed by (1) mineralogy and mineral partitioning and (2) environmental cofactors, including moisture, pH, buffering capacity, and porosity. With this type of knowledge, geoscience enhances the potential to identify covariant relations between hazard indicators and disease, and to resolve potential causal factors.

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.
