Anthropogenic mercury (Hg) emissions have driven marked increases in Arctic Hg levels,
which are now being impacted by regional warming, with uncertain ecological …

CONCENTRATIONS of mercury in the environment are increasing as a result of human
activities, notably fossil-fuel burning and incineration of municipal wastes. Increasing levels …

ANTHROPOGENIC processes, such as coal burning, waste incineration and ore refining,
are believed to contribute to the emission of mercury into the atmosphere1–5. The …

During Arctic springtime, halogen radicals oxidize atmospheric elemental mercury (Hg0),
which deposits to the cryosphere. This is followed by a summertime atmospheric Hg0 peak …

Long-range atmospheric transport and deposition are important sources of mercury (Hg) to
Arctic aquatic and terrestrial ecosystems. We review here recent progress made in the study …

The Arctic region forms a unique environment with specific physical, chemical, and
biological processes affecting mercury (Hg) cycles and limited anthropogenic Hg sources …

The Arctic ecosystem is showing increasing evidence of contamination by persistent, toxic
substances, including metals such as mercury, that accumulate in organisms. In January …
