Role on claims
Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.
This library holds 10 empirical papers on persistent pollutants with measured outcomes rather than reviews.

Indoor medians in one cohort are not global inventories, and detection is not a health effect.

TFA detection in dust?
detected in 84% of the dust samples
Key findings
39 PFAS detected; ultrashort/short-chain acids were 69–100% of PFAAs; dust TFA median 220 ng/g; C2–C3 dominated dust, water, and serum.
Methodology
Targeted 47 PFAS in dust, drinking water, urine, and serum from 81 US participants and their homes.
Limitations
Does not estimate nationwide prevalence or prove health effects of TFA at these levels.
