Per- and Polyfluoroalkyl substances (PFAS) are increasingly detected in wildlife and present concerning and unknown health risks. While there is a growing body of literature describing PFAS in seabird species, knowledge from temperate Southern Hemisphere regions is lacking. Little penguins (Eudyptula minor) can nest and forage within heavily urbanised coastal environments and hence may be at risk of exposure to pollutants. We analysed scat contaminated nesting soils (n = 50) from 17 colonies in lutruwita/Tasmania for 16 PFAS, plasma samples (n = 45) from nine colonies, and three eggs for 49 PFAS. We detected 14 PFAS across the sample types, with perfluorooctanesulfonic acid (PFOS) and perfluorohexanesulfonic acid (PFHxS) most commonly detected. Mean concentration of PFOS in plasma was 2.56 ± 4.3 ng/mL (

Marine ecosystems are increasingly threatened by anthropogenic pollutants, including plastics, persistent organic pollutants, heavy metals, oil, and emerging contaminants. This meta-analysis examined the accumulation patterns of five major contaminants-mercury (Hg), polychlorinated biphenyls (PCBs), microplastics, per- and polyfluoroalkyl substances (PFAS), and polycyclic aromatic hydrocarbons (PAHs)-in relation to trophic level and lifespan across marine species. Data synthesis revealed distinct differences in bioaccumulation and biomagnification between legacy and emerging contaminants.

Per- and polyfluoroalkyl substances (PFASs) have gained attention due to their chemical stability, bioaccumulation potential, and toxicity. The ocean serves as the ultimate sink for these compounds in the global environment. With the rapid development of the Hainan Free Trade Port, environmental pollution on Hainan Island has consequently become more pronounced.

Background: Although per- and polyfluoroalkyl substances (PFAS) have been linked to chronic liver diseases, the specific cellular and molecular mechanisms by which different PFAS contribute to human liver dysfunction remain unclear. This study aims to elucidate those mechanisms.
Methods: We exposed a multi-donor human liver spheroid model composed of multiple cell types to 20 µM of PFHxS, PFOA, PFOS, or PFNA for seven days, followed by single-cell RNA sequencing and lipid staining.

Background: Prenatal exposure to per- and polyfluoroalkyl substances (PFAS) may adversely impact child neurodevelopment; however, epidemiologic findings remain inconclusive because of small sample sizes, limited exposure variability, and differing neurodevelopmental measures. We aimed to investigate the relationship between prenatal PFAS exposure and child behavior.
Methods: We pooled data from nine study sites in the nationwide Environmental influences on Child Health Outcomes (ECHO) Cohort.
