A Decade of Post‐Fire Succession Amplifies the Effect of Wildfire on the Surface Radiation Balance and Permafrost Thaw in Subarctic Peatlands

Permafrost and Periglacial Processes, Volume 37, Issue 1, Page 124-142, January/March 2026.
ABSTRACT Increasing wildfire activity is driving permafrost thaw in subarctic peatlands across the southern Northwest Territories, but the key mechanisms and progression of thaw following fire remain poorly understood. In response, 10 years (2015–2024) of near‐continuous surface (four‐component radiation, wind, and snow) and subsurface measurements ...

Dissolved and Particulate Methylated Mercury in a Highly Productive Area of the Southern Ocean

Global Biogeochemical Cycles, Volume 40, Issue 1, January 2026.
Abstract Methylated mercury (MeHg), including dimethylmercury and monomethylmercury (MMHg), is a pollutant of concern because it biomagnifies in marine biota. The formation of MeHg in the oceans, specifically at highly productive regions and at high oxygen levels, remains elusive.

Heavy Metal Contamination in Chocolates and Candies: Sources, Health Risks, and Analytical Insights

Journal of Chemistry, Volume 2026, Issue 1, 2026.
The presence of heavy metals in chocolates and candies poses growing public health concerns, particularly for children who are frequent consumers. This review consolidates evidence on the occurrence, sources, toxicological impacts, and analytical monitoring of metals, including Pb, Cd, Hg, As, Cr, Ni, and Al, in confectionery products.

Atmospheric mercury: recent advances in theoretical, computational, experimental, observational, and isotopic understanding to decipher its redox transformations in the upper and lower atmosphere and interactions with Earth surface reservoirs [PDF]

Atmospheric Chemistry and Physics
Mercury is a volatile heavy element with no known biological function. It is present in trace amounts (on average, ∼ 80 ppb) but is not geochemically well blended in the Earth's crust.

Binding of Hg(I) and Hg(II) Ions to Amyloid‐Beta (Aβ) Peptide Variants Affect their Structure and Aggregation

ChemBioChem, Volume 26, Issue 24, December 11, 2025.
Mercury (Hg) is a possible risk factor for Alzheimer's disease, where neuronal death is related to amyloid brain plaques containing aggregated amyloid‐β (Aβ) peptides. We show that equimolar Hg(I) or Hg(II) ions inhibit normal Aβ aggregation. Hg(II) binds Aβ(1–40) with an apparent binding affinity 28 ± 8 μM.

The Aging Gut–Brain Axis: Effects of Dietary Polyphenols and Metal Exposure

Chronic Diseases and Translational Medicine, Volume 11, Issue 4, Page 251-268, December 2025.
The influence of gut microbiota on brain health ABSTRACT Diet provides essential metals, which are required for the growth, development, and well‐functioning of the body. Nonetheless, some natural and human activities add toxic heavy metals to the diet, consequently introducing them to our bodies, resulting in several disorders and death. The intestine,

Assessment of developmental neurotoxicity induced by chemical mixtures using an adverse outcome pathway concept

Environmental Health, 2020
Background In light of the vulnerability of the developing brain, mixture risk assessment (MRA) for the evaluation of developmental neurotoxicity (DNT) should be implemented, since infants and children are co-exposed to more than one chemical at a time ...
