Abstract

fetched live from OpenAlex

In 2003-2004, the Asbestos Victims Association of Quebec undertook an exploratory sampling of the air and soil in the residential community of asbestos mining towns. In the 26 houses in the Thetford Mines area, 28 air samples were collected; one outdoor air sample was collected; 14 soil samples were taken; one dust sample was taken from a windowsill. The AHERA criterion was exceeded in 15 of the 28 air samples collected and the World Trade Center criterion was exceeded in five of 26 cases. The risk of developing asbestos-related cancer following such in-home exposures over 30 years is estimated at 1 in 10,000. Soil from the driveways or backyards of nine homes was covered with residue from a tailing pile. Of 14 samples, seven had chrysotile content in excess of 10%; in three, content exceeded 60%, and one reached 100%. Dust from the windowsill had a chrysotile content of 1.2 million structures of all lengths/sq cm. These results suggest a real public health threat in the Quebec mining areas.

Full frame distilled prediction

Teacher imitation

Not 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.
