Abstract

fetched live from OpenAlex

An investigation of 16 classrooms in 4 randomly selected schools (children age 6—12) and 7 different places at the University of Waterloo, Waterloo, ON, Canada and 4 locations at Sir Wilfred Grenfell College, MUN, Corner Brook, NL, Canada were conducted to quantify emitted methyl benzoate concentrations. Methyl benzoate — as a metabolic biomarker of mold growth — has potential as an indicator for other volatile organic compound emissions outgassed by bacteria and molds. A variety of solid and indoor air grab samples were taken from the selected locations and were immediately analyzed by solid phase microextraction and gas chromatography/mass spectrometry. By this rapid method, methyl benzoate concentrations in solid samples were found to range: 5—69 and 6—22 ppb for schoolrooms and university rooms, respectively. For air samples, methyl benzoate (quantitation limit 2 ppb) was not detected in the schools, however at the universities; concentrations were as high as 25 ppb. This study supports that methyl benzoate may have use, as an indicator of mold growth, in indoor air research.

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.
