Temporal analysis of mercury concentrations in five seabird species of northwest Greenland
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 stu...
