Plastic pollution is now pervasive in the Arctic, even in areas with no apparent human
activity, such as the deep seafloor. In this Review, we describe the sources and impacts of …

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

Microplastics (MPs) are ubiquitous, and considerable quantities prevail even in the Arctic;
however, there are large knowledge gaps regarding pathways to the North. To assess …

Dramatic environmental shifts are occuring throughout the Arctic from climate change, with
consequences for the cycling of mercury (Hg). This review summarizes the latest science on …

Mercury (Hg) and especially its methylated species (MeHg) are toxic chemicals that
contaminate humans via the consumption of seafood. The most recent UNEP Global …

Rivers are an important source of mercury (Hg) to marine ecosystems. Based on an analysis
of compiled observations, we estimate global present-day Hg discharges from rivers to …

A major surface circulation feature of the Arctic Ocean is the Transpolar Drift (TPD), a current
that transports river‐influenced shelf water from the Laptev and East Siberian Seas toward …

Volcanism is a potentially important natural source of mercury (Hg) to the environment.
However, its impact on the global Hg cycle remains poorly understood despite advances …

Recent studies have shown that climate change is already having significant impacts on
many aspects of transport pathways, speciation and cycling of mercury within Arctic …

Microplastics are a globally ubiquitous contaminant, invading the most remote regions,
including the Arctic. To date, our understanding of the distribution and sources of …
