Abstract
Flaring is an accepted practice in the oil and gas industry to dispose of waste gases in Alberta. However, incomplete combustion of these gases produces a variety of volatile organic compounds (VOCs) and polycyclic aromatic hydrocarbons (PAHs). Public health concerns about gas flaring have existed for a number of years. Several facts are notable in attempting to understand what importance VOCs and PAHs from flare gas emissions have in contributing to adverse health effects in humans. Most flare stacks are located in rural areas. Current time-activity studies of humans are lacking in that they have not emphasized characterization of time-activity behavior of rural populations, who would be most susceptible to exposure from these pollutants. Available time-activity studies of primarily urban populations indicate that people spend a majority of time indoors. Numerous VOCs and PAHs measured in gas flare emissions are already present indoors, originating from indoor sources, and almost always at higher levels than outdoors. As humans inhale a majority of air indoors, inhalation exposure would be influenced to a much greater extent from being indoors than outdoors in these instances. Human health risk assessment of hazardous air pollutants emitted from burning flares must take into account indoor and other background exposures to provide useful information for public health decision-makers.Key words: flaring, air pollutants, exposure, hazardous

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 it
