15 de sept. de 2023 · Highlights • Hg sources and river fluxes were explored in the Barents region. • Local mercury risk exposure is uncertain due to limited data. • Strong seasonality is observed in Barents river Hg transport. • A new ratio of Hg-to water yield is found for the smaller Barents rivers.
Within the Arctic, the Barents region has a high industrial development, including multiple potential Hg release sources. This study presents the first overview of potential Hg release sources on Norwegian and Russian mainland draining to the Barents Sea.
1 de ago. de 2021 · Total mercury concentrations (ng/g dry weight (dw), from muscle tissue), and biological and ecological characteristics of the fishes sampled in the North-East (NE) and North- West (NW) Barents Sea in November and December 2019.
1 de jun. de 2023 · This study presents the first overview of potential Hg release sources on Norwegian and Russian mainland draining to the Barents Sea.
1 de dic. de 2022 · Mercury and trace element geographic patterns are best explained by the origin and transportation of fine grain sediment towards the Eurasian Basin, with scavenging by both particulate organic carbon and metal oxides as significant delivery mechanisms.
Abstract. Although mercury (Hg) in polar ecosystems has been well-studied, there is little information on Hg in the Arctic during low-productivity seasons like the polar night. We quantified Hg concentrations, carbon, and nitrogen stable isotope ratios (δ 13 C and δ 15 N) in the muscle of polar cod (Boreogadus saida), Atlantic cod (Gadus ...
15 de may. de 2020 · Abstract. Temporal trends of total mercury (THg) were examined in female polar bear ( Ursus maritimus) hair ( n = 199) from the Barents Sea in 1995–2016. In addition, hair values of stable isotopes ( n = 190–197) of carbon (δ 13 C), sulfur (δ 34 S), and nitrogen (δ 15 N) and information on breeding status, body condition, and age were ...
