Summary: This study tested the stability of mercury concentrations and stable isotope ratios in preserved fish under museum preservation practices. Loss of unidentified constituents during preservation led to increased mercury concentrations in fish muscle. Low-mercury fish were susceptible to contamination with inorganic mercury when intentionally spiked or passively leached from contaminated wild fish. However, the conservative nature of methylmercury allowed for quantitative correction of the contamination. The findings suggest the potential use of preserved fish from museums for generating spatiotemporal baselines for the Minamata Convention on Mercury, with precautions recommended for maximizing inference strength.

Summary: Arctic rivers are a significant source of mercury (Hg) to the Arctic Ocean, but there is limited knowledge about the terrestrial release sources and Hg levels in these rivers. This study provides an overview of potential Hg release sources in the Barents region, known for its high industrial development. The results highlight occasional exceedance of pollution control limits in freshwater bodies near these sources, posing a concern for local populations and wildlife. New data on Hg levels in Barents rivers show strong seasonal variations and contribute to international efforts in reducing Hg pollution.

Summary: This study assessed the importance of migrating oceanic salmon, volcanic activity, and atmospheric deposition to fish mercury burden by analyzing lake trout in 13 remote lakes in southwestern Alaska. The results showed that volcanic activity is a significant additional source of mercury in proximate lakes, while migratory salmon contribute little methylmercury directly to lake trout. The study also found niche partitioning and a complex suite of ecological interactions in lake trout populations.

Summary: Volcanism is a potentially important natural source of mercury (Hg) to the environment, but its impact on the global Hg cycle is poorly understood, leading to uncertainty in assessing the relative contributions of natural and anthropogenic Hg sources to the global atmosphere. Research shows that arc volcanoes emit 3-fold higher Hg fluxes on average compared to non-arc volcanoes, despite the latter having significantly higher Hg concentrations in their plumes.

Summary: The increasing mercury isotope ratios in lake sediment cores from pre-industrial to present-day are suggested to be a global phenomenon. It is mainly attributed to the increased contribution of mercury from local to regional anthropogenic sources. The magnitude of mercury isotope changes are more influenced by baseline mercury isotope ratios rather than the level of THg input.

Summary: Research indicates that mercury deposition in lake sediments in Australia's Hunter Valley and Latrobe Valley has significantly increased since the commissioning of coal-fired power plants. The Latrobe Valley has higher mercury emissions due to higher concentrations in lignite coal, lax regulation, and older pollution-control technologies adopted by coal-fired power plants in that region. Australia faces the challenge of ratifying the Minamata Convention and developing better regulation policies to reduce mercury emissions in the future.

Summary: The artisanal and small-scale gold mining sector in Ghana continues to grow, but the impacts caused by mercury use are becoming increasingly severe. Despite previous bans and increased monitoring efforts, the country has not been successful in significantly reducing mercury use and its associated impacts. The lack of mercury alternatives, funding, and education support makes addressing this issue more challenging.

Summary: The accuracy of mercury dendrochemistry is questioned due to knowledge gaps in Hg translocation in tree-ring. Results show that Hg concentrations in tree-ring do not accurately reconstruct the temporal trend of Hg production. The isotopic profiles of Hg in tree-ring exhibit variability and can be used to reconstruct atmospheric Hg pollution levels and emission source shifts.

Summary: This study presents an 8500-year record of high-resolution pollen, non-pollen palynomorph, microscopic charcoal, and selected geochemical data to analyze vegetation changes in the Xistral Mountains, Galicia, North-West Iberia. The results indicate that human disturbance, fire, and climate change are the main factors influencing vegetation development over the past eight millennia. Human impact on vegetation became more significant during the late Holocene, resulting in the permanent decline of deciduous forests and the creation of a cultural landscape.
