Historically, glaciers have been seen as pristine environments. However, recent research has shown that can accumulate and store contaminants over long timescales, through processes such atmospheric deposition, sedimentation, glacial hydrology mass movements. Studies identified numerous anthropogenically derived within the global cryosphere, including six we focus on here: fallout radionuclides; microplastics; persistent organic pollutants; potentially toxic elements; black carbon...
The accumulation of fallout radionuclides (FRNs) from nuclear weapons testing and accidents has been evaluated for over half a century in natural environments; however, until recently their distribution abundance within glaciers have poorly understood. Following series individual studies FRNs, specifically 137Cs, 241Am 210Pb, deposited on the surface glaciers, we now understand that cryoconite, material commonly found supraglacial environment, is highly efficient accumulator both artificial...
Abstract Mountain glaciers are crucial sources of fresh water, contributing directly and indirectly to energy food supplies for hundreds millions people. Assessing the impact diminishing glacial meltwater contributions security this resource is critical as we seek manage adapt changing freshwater dynamics in a warming world. Both water quantity quality influence (in)security, so understanding fluxes sediment contaminants through proglacial systems required holistic assessment contribution...
Under climatic warming, glaciers are becoming a secondary source of atmospheric contaminants originally released into the environment decades ago. This phenomenon has been well-documented for near emission sources. However, less is known about polar ice sheets and caps. Radionuclides one that can be remobilised through melting accumulate in cryoconite material on surface glaciers. To understand cycling radionuclides glacial contexts, we evaluate radioactivity samples from Flade Isblink, High...
Anthropogenic contamination has been detected in glacial and proglacial environments around the globe. Through mechanisms of secondary release, these contaminants are finding their way into hydrological systems downstream environments, with potential to impact hundreds millions people who rely on meltwater for water, food energy security worldwide. The first part our progress report outlined sources accumulation (Part I: Inputs accumulation). Here we assess processes contaminant pathways...
Mercury (Hg) is a chemical element recognized as one of the most toxic among all naturally occurring elements, with health risks depending on its form, concentration, route and time exposure. appears in environment result human activities, which include burning coal or lignite, improper waste disposal, oil refining, use mercury-containing pesticides fertilizers, industrial development such mining, chemical, pharmaceutical paper industries. The also consequence natural phenomena, are volcanic...
Under climatic warming and increased melting, glaciers ice caps are becoming secondary sources of contaminants deposited decades ago. Cryoconite, an organic-rich material found on the surface many glaciers, is particularly efficient at accumulating airborne due to biogeochemical exchanges with organic matter within cryoconite. Atmospherically derived radioactive isotopes, commonly referred as fallout radionuclides, have now been accumulate in cryoconite globally. However, data from polar...
<p>Glaciers are temporary repositories for radionuclides and other airborne contaminants (eg. heavy metals). Retreat of glaciers results in the release these to downstream ecosystems where they can be accumulated by biota, with further consequences along trophic chain. Fallout radionuclides, especially Pu released from nuclear weapons testing accidents, concentrates on glacier surfaces cryoconite granules. These aggregates mineral organic components associated biological...
<p>Historically, glaciers have been seen as pristine environments. However, research has shown that can accumulate and store contaminants through processes such atmospheric deposition, mass movements, anthropogenic activities. Numerous anthropogenically naturally-derived found within glacial sediments, including fallout radionuclides, potentially toxic elements, heavy metals. The introduction of these often come from human activities the use agricultural fertilisers, carbon...
