| dc.description.abstract | Anthropogenic emissions have led to widespread mercury contamination in aquatic ecosystems globally, surpassing pre-industrial levels. This phenomenon extends to Arctic environments, where numerous seabird colonies reside, facing heightened exposure due to their dietary habits and longevity. Our study focused on five seabird species in northwest Greenland, spanning the years 2010 to 2023. By analyzing blood samples for mercury levels alongside carbon and nitrogen stable isotopes, we assessed temporal trends in contamination. Results revealed moderate to low risks of mercury toxicity across species, with certain individuals exceeding safe thresholds. Variations in mercury concentrations among species and temporal trends underscore the complexity of Arctic mercury dynamics. These findings contribute vital insights into regional mercury patterns and aid ongoing efforts, such as the Minamata Convention, aimed at mitigating mercury's environmental impact. Understanding these trends is crucial for safeguarding Arctic ecosystems and the species reliant upon them. | en_US |
