Mercury from centuries-old pollution still circulating in oceans, study finds

Stable isotopes unveil ocean transport of legacy mercury into Arctic food webs - Nature Communications

Anthropogenic activities have caused large-scale mercury (Hg) pollution in the Arctic reaching toxic levels, but knowledge of sources and pathways is sparse. Here, we present Hg stable isotope data in peat and key aquatic predatory species collected across Greenland. We observe distinct regional differences with significantly lower total Hg and higher δ202Hg in central-western versus northern-eastern Greenland influenced by different ocean curre…

Centuries-old mercury pollution hidden in the ocean threatens arctic wildlife

Despite global reductions in mercury emissions, mercury concentrations in Arctic wildlife continue to rise. A new study published in Nature Communications by researchers from Aarhus University and the University of Copenhagen reveals that ocean currents may be transporting legacy mercury pollution to the Arctic—posing a long-term threat to ecosystems and human health.

Mercury from centuries-old pollution still circulating in oceans, study finds

Toxins released by long-extinguished fossil fuel fires and gold smelters are showing up in the bodies of Arctic wildlife, according to new research pointing to mercury released by pollution hundreds of years ago still circulating in ocean currents. A paper published on Thursday in Nature Communications sought to untangle a paradox: why levels of the potent neurotoxin…

Mercury of centuries ago threatens the Arctic Ocean - Evidence Network

Marine currents transport the residual mercury of industrial processes to the Arctic glacial sea: the pollutant persists in the 300 years. The ocean currents They ...
