Abstract

fetched live from OpenAlex

Flame retardants and phthalates are commonly used in consumer products and building materials, and as such, are prevalent in indoor air. Polycyclic aromatic hydrocarbons (PAHs) can have both indoor and outdoor sources and can also be found in indoor air. Flame retardants, phthalates, and PAHs were measured in indoor air in 71 units in low-income social housing multi-unit residential buildings (MURBs) using silicone rubber (polydimethylsiloxane or PDMS) passive air samplers deployed for 1 week in Toronto, Canada, in late spring and winter of 2017. Tris(1,3-dichloro-2-propyl) phosphate (TDCiPP), diethyl phthalate (DEP), and phenanthrene were the dominate flame retardant, phthalate, and PAH, with median concentrations of 1640 pg/m3 and 1840 and 79.0 ng/m3, respectively. Flame retardant and phthalate concentrations were 2 to 18 times higher than those in predominantly detached and semi-detached houses in Toronto measured using the same passive samplers. These results indicate higher exposures among residents of low-income social housing (63% with income <$23,400) than those of higher socio-economic status single-family dwellings (67% with income >$100,000).

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.
