What indoor household source contributes to PFAS exposure through inhalation or ingestion?

Household dust containing leached chemicals from furniture treatments and electronics

An often unrecognized pathway for human exposure to PFAS involves the indoor environment, specifically through household dust. Since these chemicals are integrated into numerous household items, including specialized electronics and various forms of furniture treatments designed for water or stain resistance, the PFAS compounds can leach out of these products over time. Once released, these persistent chemicals integrate into the general household dust. This contaminated dust then becomes an exposure vector, as it can be inhaled or ingested—a process particularly concerning for small children who spend significant time close to the floor surface where dust settles most heavily.
