Article Synopsis
- Contaminants of emerging concern (CECs) like bisphenols and phthalates are found in aquatic environments and can disrupt wildlife biology, but their presence in seabirds, like common eiders, is not well-studied.
- This research sampled blood from 18 female common eiders in the Baltic Sea during their breeding season to analyze CEC levels and how they change over incubation.
- Findings revealed that while some CECs were present in significant amounts, late-breeding eiders showed higher concentrations than early-breeders at specific times, highlighting the need for ongoing CEC monitoring in eiders and related prey species.
The Baltic Sea is among the most polluted seas worldwide with elevated concentrations of trace elements (TEs). TEs can induce negative effects on organisms and may be transferred to eggs causing endocrine-disrupting effects on embryos. The Baltic Sea population of common eider (Somateria mollissima) has declined over the last thirty years, but the potential contribution of TEs to this decline is understudied.

- Neonicotinoids are a type of insecticide that can harm farmland birds, but there's not much known about their effects on waterbirds.
- In a study in Finland, scientists looked for seven types of neonicotinoids in the blood of female common goldeneyes but couldn’t find any.
- The results suggest that these bird habitats are currently safe from neonicotinoid exposure, but more research is needed to understand the impact on the food chain and other birds.
Arctic wildlife is facing multiple stressors, including increasing plastic pollution. Seabirds are intrinsic to marine ecosystems, but most seabird populations are declining. We lack knowledge on plastic ingestion in many arctic seabird species, and there is an urgent need for more information to enable risk assessment and monitoring.

A subset of such patients develops early coagulation dysfunction characterized as acute traumatic coagulopathy (ATC), with a poor prognosis. The mechanisms contributing to ATC remain incompletely understood.
