The Arctic cryosphere is collapsing, posing overlapping environmental risks. In particular,
thawing permafrost threatens to release biological, chemical and radioactive materials that …

Global environmental changes not only contribute to the modification of global pollution
transport pathways but can also alter contaminant fate within the Arctic. Recent reports …

For more than five decades, research has been conducted at Ny-Ålesund, in Svalbard,
Norway, to understand the structure and functioning of High-Arctic ecosystems and the …

Climate change is transforming Arctic ecosystems in ways that are influencing the transport
and accumulation of contaminants. The spatial and temporal variability of heavy metal …

The bioavailability of essential and non-essential elements in vegetation is expected to
influence the performance of free-ranging terrestrial herbivores. However, attempts to relate …

Passive air samples were deployed in Ny-Ålesund and London Island (Svalbard, High
Arctic) annually for seven years (2011–2018) to investigate concentrations, temporal trends …

The Arctic region is threatened by climate change and pollution caused by human activities
which potentially influence the elemental concentrations available to and from the biota. To …

Persistent organic pollutants (POPs) are xenobiotic chemicals of global concern due to their
long-range transport capabilities, persistence, ability to bioaccumulate, and potential to have …

Considerable amounts of previously deposited persistent organic pollutants (POPs) are
stored in the Arctic cryosphere. Transport of freshwater and terrestrial material to the Arctic …

Climate change driven increases in permafrost thaw and terrestrial runoff are expected to
facilitate the mobilization and transport of mercury (Hg) from catchment soils to coastal areas …
