Those PFASs that have the potential to be converted into long-chain perfluoroalkyl carboxylic or sulfonic acids are paid particular attention, which are currently the focus of regulatory action.
Global distribution of perfluorooctane sulfonate in wildlife.
Fish-eating, predatory animals such as mink and bald eagles contained concentrations of PFOS that were greater than the concentrations in their diets, suggesting that PFOS can bioaccumulate to higher trophic levels of the food chain.
Mass loading and fate of perfluoroalkyl surfactants in wastewater treatment plants.
The observed increase in mass flow of several PASs may have resulted from biodegradation of precursor compounds such as fluorotelomer alcohols, which is supported by significant correlations in themass flow of PFOA/PFNA and PFDA/PFUnDA.
Perfluorooctanesulfonate and related fluorochemicals in human blood from several countries.
The results suggested the existence of sources with varying levels and compositions of perfluorochemicals, and differences in exposure patterns to these chemicals, in various countries.
A global survey of perfluorinated acids in oceans.
A survey of perfluorooctane sulfonate and related perfluorinated organic compounds in water, fish, birds, and humans from Japan.

In this study, concentrations and distribution of PFOS, perfluorohexane sulfonate (PFHS), and perfluorobutane sulf onates (PFBS) were determined in samples of surface water, fish and bird blood and livers, and human blood collected in Japan.
Bisphenol S in urine from the United States and seven Asian countries: occurrence and human exposures.
The daily intake of BPS was estimated on the basis of urinary concentrations using a simple pharmacokinetic approach and there were no significant differences in BPS concentrations between genders (male versus female), or among age groups (categorized as ≤ 19, 20-29, 30-39, 40-49, and ≥ 50 years), or races (Caucasian versus Asian).

E eggs of fish contained notable concentrations of PFOS, suggesting oviparous transfer of this compound, and the biomagnification factor (BMF) of perfluorinated compounds in higher trophic-level organisms such as salmonid fishes, mink, and eagles were based on the concentrations in livers or plasma.
An assessment of sources and pathways of human exposure to polybrominated diphenyl ethers in the United States.
