Indoor and outdoor SO<sub>2</sub> in a community near oil sand extraction and production facilities in northern Alberta
Bibliographic record
Abstract
A baseline study measuring indoor and outdoor sulfur dioxide (SO 2 ) levels was undertaken in a small native community (Fort McKay) in northern Alberta. The objective was to assess whether proximity of numerous oil sand operations affected air quality in the community. A passive sampling device was deployed for 96 h durations at 30 randomly selected homes over a 6 week period such that 75% of homes were sampled during weekdays and 25% during weekends. The common living area of each home (kitchen or family room) was sampled indoors. Outdoor passive samplers were attached to a sampling stand under a shelter in the yard. Indoor SO 2 levels were all less than a method detection limit of 1.3 µg/m 3 (n = 30). The median outdoor level was 1.7 µg/m 3 (n = 28, range 1.3 to 3.7 µg/m 3 , 70% > method detection level). Results of testing to determine accuracy and precision of the monitors showed both measures to be within 35% based on a 96 h average measurement. Overall, these levels are considered very low and consistent with levels observed elsewhere in Alberta. Key words: sulfur dioxide, passive sampling, indoor and outdoor air.

How this classification was reachedexpand
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.
