Article Synopsis
- PFAS (per- and polyfluorinated alkyl substances) are man-made chemicals that don’t break down easily and accumulate in the environment, which was analyzed in various mammal and bird species across Germany and Denmark.
- The study measured PFAS concentrations in 12 mammal species and 2 bird species while considering their diet (herbivores, omnivores, carnivores), habitat (land vs. water), and tissue type (liver vs. muscle).
- Results showed that carnivores had the highest PFAS levels, with significant variation in specific compounds depending on their trophic class and habitat, revealing more complex contamination patterns than previously understood.
Article Synopsis
- Researchers analyzed wild boar liver samples from three different areas to assess their ability to indicate PFAS contamination in the environment, focusing on areas with varying levels of pollution.
- A total of 31 PFAS compounds were identified, with significantly higher concentrations found in contaminated sites compared to background levels, particularly with legacy compounds like PFOS and PFOA.
- The study concluded that wild boar livers effectively reflect the local soil contamination, making them useful bioindicators for monitoring PFAS levels in terrestrial ecosystems.
Apex predators are good indicators of environmental pollution since they are relatively long-lived and their high trophic position and spatiotemporal exposure to chemicals provides insights into the persistent, bioaccumulative and toxic (PBT) properties of chemicals. Although monitoring data from apex predators can considerably support chemicals' management, there is a lack of pan-European studies, and longer-term monitoring of chemicals in organisms from higher trophic levels. The present study investigated the occurrence of contaminants of emerging concern (CECs) in 67 freshwater, marine and terrestrial apex predators and in freshwater and marine prey, gathered from four European countries.

The current imaging modality to screen CKCS for CM/SM is MRI of the brain and cervical spine. Magnetic resonance imaging provides good soft tissue detail and contrast of the cerebellum and cervical spinal cord.
