A human-health risk assessment of dietary methylmercury exposure in Fort Albany First Nation
Bibliographic record
Abstract
In Northern First Nations communities, traditional diets are a primary pathway for essential nutrients and exposures to environmental contaminants. Due to long-range transport and industry pollution, Fort Albany First Nation is a community at risk of methylmercury exposures through fish. It’s ability to bioaccumulate, and its neurotoxic and developmental impacts, make its presence a concern. This study assessed five fish species for methylmercury from the Albany River. All species, except for Pike, demonstrated a positive relationship with mercury concentrations increasing with length. A human health risk assessment was conducted and demonstrated twice the risk of exceeding the reference dose for children ages 3 to 6 for all species, and 6 to 11 for all species, excluding Whitefish. It is recommended that vulnerable populations consuming certain species of fish reduce their intakes or encourage community trading. Furthermore, there is a need for more thorough testing for mercury along the river basin

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.
