Assessment of background concentrations of organometallic compounds (methylmercury, ethyllead and butyl- and phenyltin) in French aquatic environments [PDF]

Water Research, 2016
The aim of this work is to estimate background concentrations of organometallic compounds, such as tributyltin (TBT), dibutyltin (DBT), monobutyltin (MBT), triphenyltin (TPhT), diphenyltin (DPhT), monophenyltin (MPhT), methylmercury (MeHg), inorganic mercury (iHg) and diethyllead (Et2Pb) in the aquatic environment at the French national scale.

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 ...

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.

Impaired cross-talk between the thioredoxin and glutathione systems is related to ASK-1 mediated apoptosis in neuronal cells exposed to mercury

Redox Biology, 2017
Mercury (Hg) compounds target both cysteine (Cys) and selenocysteine (Sec) residues in peptides and proteins. Thus, the components of the two major cellular antioxidant systems – glutathione (GSH) and thioredoxin (Trx) systems – are likely targets for ...

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.

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

Anticoagulant Rodenticides Contribute to a Decline in an Urban Carnivore

Animal Conservation, Volume 29, Issue 5, Page 545-556, October 2026.
Anticoagulant rodenticides (ARs) have been shown to negatively affect carnivores globally and are closely tied to human activity and development. We examined drivers of annual survival in bobcats persisting on a residentially developed barrier island over 16 years.
