“…An example of species-specific biokinetics is provided by a recent comparative study between co-occurring great tits (Parus major) and blue tits (Cyanistes caeruleus) across a gradient of exposure, showing that even closely related species can differ in how they sequester long carbonchain versus short carbon-chain perfluoroalkyl carboxylic acids (PFCAs) (Lasters et al, 2021). At higher-level taxonomic scales, terrestrial plants and herbivorous invertebrates tended to sequester more short-chain PFCAs, whereas vertebrate animals and higher trophic level invertebrates tended to sequester more long-chain PFCAs (Groffen et al, 2022).…”

Per- and polyfluoroalkyl substances (PFAS) threaten human and wildlife health, but their movement through food webs remains poorly understood. Contamination of the physical environment is widespread, but particularly concentrated at military installations. Here we measured 17 PFAS in wild, free-living mammals and migratory birds at Holloman Air Force Base (AFB), New Mexico, USA, where wastewater catchment lakes form biodiverse oases. PFAS concentrations were among the highest ever reported in animal tissues, and high levels have persisted for at least three decades. The hazardous long carbon-chain form, perfluorooctanosulfonic acid (PFOS), was most abundant, with liver concentrations averaging tens of thousands of ng/g wet weight (ww), reaching as high 97,000 ng/g (ww) in a 1994 specimen of white-footed mouse (Peromyscus leucopus) and 38,000 ng/g ww in a duck, the American wigeon (Mareca americana). Perfluorohexanesulfonic acid (PFHxS) averaged thousands of ng/g ww in the livers of birds and house mice, but one order of magnitude lower in the livers of upland desert rodent species. PFAS levels were strikingly lower at control sites, even for highly mobile migratory species. Tissue concentrations were correlated within individuals, and consistently higher in liver than in muscle or blood. Twenty of 23 vertebrate species sampled at Holloman AFB were heavily contaminated, representing multiple trophic levels and microhabitats, and implicating a range of pathways for PFAS spread: ingestion of surface water, sediments, and dust; foraging on aquatic invertebrates and plants by secondary consumers; and preying upon small vertebrates by higher level consumers, including consumption of game species by hunters. Unlike in other aquatic systems, piscivory was not an important pathway of PFAS uptake. In sum, legacy PFAS at a desert wetland have permeated the local food web across a period of decades, severely contaminating resident and migrant animals, and likely exposing humans via game meat consumption and outdoor recreation.

“…Decades-long disposal resulted in contamination of the environment [2,3]. PFASs tend to accumulate in the tissues of humans, wildlife, and plants [4,5], where they may cause severe toxic effects [5,6]. Despite several regulations for some longchained PFASs, environmental concentrations are often still high [4,7].…”

“…PFASs tend to accumulate in the tissues of humans, wildlife, and plants [4,5], where they may cause severe toxic effects [5,6]. Despite several regulations for some longchained PFASs, environmental concentrations are often still high [4,7]. Furthermore, the alternatives used, particularly short-chained PFASs, have higher mobility in the environment due to their higher water solubility and lower sorption of solids [8].…”

In this study, we grew radish (Raphanus raphanistrum subsp. sativus L.) and broad beans (Vicia faba L.) in a greenhouse on soils spiked with a mixture of 15 per- and polyfluoroalkyl substances (PFASs) and investigated the association between accumulated ∑PFAS concentrations, growth, and hormone levels. Short-chained PFASs dominated aboveground tissues, whereas long-chained PFASs were most abundant in the plant roots. Our results showed that the presence or absence of exodermal Casparian strips, as well as the hydrophobicity and anion exchange capacities of PFASs, could explain the translocation of PFASs within plants. Significant associations found between accumulated PFAS concentrations and levels of gibberellins (GA1 and GA15), methionine, and indole-3-acetic acid (IAA) imply potential effects of PFASs on plant development and growth. This study provides the first evidence of associations between PFAS accumulation in plants and growth hormone levels, possibly leading to growth reduction of the apical dome and effects on the cell cycle in pericycle cells and methionine metabolism in plants.
