Carbon recycling, energy flux, and mercury dynamics along a river affected by multiple disturbances

Limnology and Oceanography, Volume 71, Issue 11, November 2026.
Abstract Small hydroelectric power plants, such as run‐of‐river dams (RORs), are increasingly promoted as low‐impact renewable energy sources, yet their disturbance on mercury (Hg) cycling remains poorly evaluated in impact assessments. Recent work suggests that ROR impacts may be underestimated, as transient Hg increases were observed in fish ...

Illegal Gold Mining in the Brazilian Amazon: Environmental Degradation in Yanomami Indigenous Lands, and Regulatory Failures

Sustainable Development, Volume 34, Issue 7, Page 9232-9246, November 2026.
ABSTRACT Illegal gold mining has emerged as a major sustainability threat in the Amazon, eroding Indigenous rights, forest integrity, and climate mitigation efforts. This study examines how international market incentives relate to the expansion of illegal mining and associated deforestation within the Yanomami Indigenous Territory (YIT) from 2008 to ...

Protective Effects of Vitamin E and Selenium Nanoparticles Against Mercury Induced Growth, Blood and Histopathological Changes in Tilapia, Oreochromis niloticus

Veterinary Medicine and Science, Volume 12, Issue 6, November 2026.
• Mercury caused significant loss in growth and feed conversion efficiency, altered blood profiles and increased gill and intestinal pathologies of tilapia. • Vitamin E and Selenium nanoparticles supplementations significantly improved growth and feed conversion efficiency, blood profiles and gill and intestinal pathologies of tilapia.

Eutectic Gallium‐Indium as a Potential Non‐Toxic Replacement in Mercury Intrusion Porosimetry

Advanced Materials Technologies, Volume 11, Issue 20, 21 October 2026.
A practical alternative to mercury intrusion porosimetry is presented using non‐oxidized eutectic gallium‐indium. An eGaIn Filling Station enables oxygen‐free preparation of standard penetrometers, and the resulting measurements faithfully reproduce pore‐size distributions and intrusion volumes measured with mercury across several standard reference ...

Consensus document on the prevention of methylmercury exposure in Spain

, 2015
The beneficial effects of fish consumption in both children and adults are well known. However, the intake of methylmercury, mainly from contaminated fish and shellfish, can have adverse health effects.

Potentially Toxic Elements and Male Reproductive Toxicity: Mechanisms, Implications, and Protective Strategies: A Narrative Review

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 10, October 2026.
Potentially toxic elements impair male reproductive function through oxidative stress, DNA damage, mitochondrial dysfunction, inflammation, endocrine disruption and epigenetic alterations. Antioxidants, phytochemicals, chelating agents and healthy lifestyle interventions may help mitigate testicular toxicity and preserve fertility.

Organic and Inorganic Pollutants, Oxidative Stress Biomarkers, and Electrophoretic Protein Profiles in an Endangered Thresher Shark (Alopias vulpinus) From Southeastern Brazil: A Case Study

Environmental Toxicology, Volume 41, Issue 10, Page 833-848, October 2026.
ABSTRACT A comprehensive screening of different environmental contaminants (total metals, thermostable metal fractions associated with detoxification, and persistent organic pollutants) was conducted in an endangered common thresher shark (Alopias vulpinus ) individual incidentally captured in southeastern Brazil.

Disease burden of methylmercury in the German birth cohort 2014.

PLoS ONE, 2018
This study aimed to estimate the disease burden of methylmercury for children born in Germany in the year 2014. Humans are mainly exposed to methylmercury when they eat fish or seafood. Prenatal methylmercury exposure is associated with IQ loss.

Patterns and Drivers of Mercury Accumulation in Croplands, a Meta‐Analysis

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.
Abstract Mercury (Hg) is a potent neurotoxin that poses risks to human and environmental health, particularly in regions influenced by anthropogenic Hg emissions. Although Hg emissions have declined across North America and Europe following regulatory controls and phase‐outs, emissions remain elevated in some regions due to activities such as artisanal
