Use of a new enrichment nanosorbent for speciation of mercury by FI-CV-ICP-MS [PDF]

open access: yes, 2015
Mercury is one of the most toxic environmental pollutants and its effects on human and ecosystem health are well known. All mercury species are toxic, with organic mercury compounds generally being more toxic than inorganic species.

Development of a High‐Sensitivity Electrochemical Biosensor for Domoic Acid and Its Cellular Impact on Human Stem and Neuron‐Like Cells

open access: yesFood Science &Nutrition, Volume 14, Issue 5, May 2026.
Integrated workflow of domoic acid (DA) detection in seafood using a high‐sensitivity electrochemical biosensor and subsequent evaluation of DA‐induced cellular responses. (A) DA monitoring in seafood: Marine samples (European anchovy and mussels from the Marmara and Black Sea) were collected, extracted using a 1:1 methanol/water mixture, and analyzed ...

The Mercury-Tolerant Microbiota of the Zooplankton Daphnia Aids in Host Survival and Maintains Fecundity under Mercury Stress. [PDF]

open access: yes, 2019
Many aquatic organisms can thrive in polluted environments by having the genetic capability to withstand suboptimal conditions. However, the contributions of microbiomes under these stressful environments are poorly understood.

Human embryonic stem cell-derived test systems for developmental neurotoxicity: a transcriptomics approach [PDF]

open access: yes, 2012
Developmental neurotoxicity (DNT) and many forms of reproductive toxicity (RT) often manifest themselves in functional deficits that are not necessarily based on cell death, but rather on minor changes relating to cell differentiation or communication ...

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]

open access: yesAtmospheric 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.

Monitoring mercury across the National Wildlife Refuge System using a biosentinel approach

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 4, May 2026.
We measured mercury concentrations in 1,356 dragonfly larvae collected from 30 National Wildlife Refuges across the United States and found wide variability among refuges, spanning the full range reported for other protected lands. Using a management‐focused mercury impairment index, 80% of refuges contained sites classified as moderate or higher risk.

Effects of Temperature on Mercury Methylation and Demethylation in Boreal Wetland Soils

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Wetlands are critical sites for methylmercury (MeHg) production, a neurotoxin that bioaccumulates in organisms and biomagnifies in aquatic food webs. Net MeHg production in wetland soil depends on the balance between microbially mediated MeHg production and the degradation of MeHg through both microbial and abiotic pathways.
