Exposure to PFAS is associated with telomere length dynamics and demographic responses of an arctic top predator
International audience Environmental factors that can influence telomeres are diverse, but the association between telomeres and exposure to environmental contaminants is far to be elucidated. To date, prior studies focused on legacy persistent chlorinated pollutants POPs, while the effects of poly-...

International audience Environmental factors that can influence telomeres are diverse, but the association between telomeres and exposure to environmental contaminants is far to be elucidated.

Here, we investigated the associations among PFAS congeners, absolute telomere length (cross-sectional approach), and telomere dynamics (rate of telomere length change over time, longitudinal approach), in one of the most contaminated arctic top predators, the glaucous gull Larus hyperboreus from Svalbard.
