Environmental exposure and ecological risk of perfluorinated substances (PFASs) in the Shaying River Basin, China
Science
19 Jul 2023 | Chemosphere
PFAS exposure via inhalation of particulate matter was found to be dominated by low levels of PFSAs and PFCAs, but inhalation exposure is still important due to its long-term and cumulative nature.

Concentrations and isomer profiles of perfluoroalkyl carboxylates in house rats (Rattus norvegicus) and human blood: Implication for human exposure sources
Science
11 Apr 2023 | Sci Total Environ
Fluorotelomer alcohol exposure and subsequent biotransformation is an important source of PFCAs in humans and rats that live nearby.

Invited Perspective: PFAS in Breast Milk and Infant Formula—It’s Time to Start Monitoring
Science
2 Mar 2023 | EHP
The author states that health-based guidance values are needed for infant PFAS exposures for the myriad of legacy and emerging PFAS—not just the four drinking water screening values used in the U.S.

Emerging and Legacy Perfluoroalkyl Substances in Breastfed Chinese Infants: Renal Clearance, Body Burden, and Implications
Science
2 Mar 2023 | Environ Health Perspect
Legacy and novel short-chain PFAS were found widespread in human breast milk, with 6:2 Cl-PFESA displaying a median half-life of 49 years in infants.

Associations between per and polyfluoroalkyl ether sulfonic acids and vitamin D biomarker levels in Chinese newborns
Science
5 Jan 2023 | Sci Total Environ
Exposure to legacy PFAS, including PFTrDA, PFHxS, and PFOS, might disturb vitamin D status in newborns.

Occurrence, partitioning and transport of perfluoroalkyl acids in gas and particles from the southeast coastal and mountainous areas of China
Science
5 Dec 2022 | Environ Sci Pollut Res Int.
The longer the fluorinated carbon chain length of the PFAA, the more the PFAA tended to exist in the particulate phase, and PFAS in China can be widely spread through the atmosphere due to winter monsoon winds.

First report on per- and polyfluoroalkyl substances (PFASs) in coral communities from the Northern South China sea: Occurrence, seasonal variation, and interspecies differences
Science
20 Sep 2022 | Environ Pollut
PFHxS accounted for 43% of total PFAS detected in corals with short-chain PFAS concentrations higher than legacy PFAS, though concentrations depended on seasonal factors and coral type.

Suspect screening and nontargeted analysis of per- and polyfluoroalkyl substances in representative fluorocarbon surfactants, aqueous film-forming foams, and impacted water in China
Science
9 Jul 2022 | Environ. Int.
69 PFAS were identified in Chinese fluorosurfactants such as those used in aqueous film-forming foams, and high concentrations of neutral PFAS were found in polymer-based products.
