ChemistryOpen, Volume 15, Issue 8, August 2026.Hg2+ is considered one of the most dangerous heavy metal pollutants. The fumed‐Si‐Pr‐TAP was prepared by functionalizing fumed‐silica with 3‐(chloropropyl)trimethoxysiliane and 2,4,6‐triaminopyrimidine (TAP). Fumed‐Si‐Pr‐TAP can detect Hg2+ ions in aqueous solutions with good sensitivity and selectivity.

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.Abstract Extreme storms and flooding can remobilize legacy contaminants stored in the sediment bed; however, event‐scale models that resolve the transport of these materials remain underdeveloped. This study developed a numerical model of contaminated sediment transport during Hurricane Harvey (August 2017), which struck the upstream reaches of ...

Implications of Maternal Toxicant Effects on Size‐Dependent Fisheries' Management: A Meta‐Analysis
Fish and Fisheries, Volume 27, Issue 4, Page 895-911, July 2026.Larger, older fish transfer higher mercury and PCB concentrations to their eggs, significantly reducing offspring hatching success, survival and growth rates in contaminated aquatic ecosystems. These findings suggest that the reproductive benefits of big old fat fecund female fish may be compromised by maternal toxicant transfer in polluted waters ...

Epigenetic Perspectives on Maternal Gut Microbiota's Impact on Embryonic and Fetal Development
Comprehensive Physiology, Volume 16, Issue 3, June 2026.This review summarizes how maternal health and nutrition shape gut microbiota via epigenetics to regulate embryonic development. It highlights microbiota‐embryo interactions, disruption by prenatal chemical exposures, and personalized nutrition for disease prevention, offering novel insights and therapeutic targets.

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.

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.ABSTRACT Lentic ecosystems are vulnerable to contamination by trace elements, which can accumulate and pose risks to aquatic life and human health. In a large, developing country such as Brazil, marked by vast geographic, environmental, and socioeconomic diversity, it is crucial to understand how these factors shape research on this group of ...

Methylmercury and the skeletal muscle receptor
Journal of Pharmacy and Pharmacology, 1976 AbstractMethylmercury at a bath concentration of 2 × 10−5 m was capable of inhibiting muscular contractions of the isolated rat phrenic-nerve hemidiaphragm preparation. At the height of inhibition, nerve action potential could still be recorded and the muscles continued to respond to direct stimulation. The inhibition was not reversible with l-cysteine

Public Health Challenges, Volume 5, Issue 2, June 2026.Consuming prenatal supplements, farmed chicken/eggs, and vegetables during pregnancy and the first 3 years of life showed protective relation with ASD compared with healthy controls. Consuming farmed fish and fruits during the same period, alongside maternal substance/drug misuse during pregnancy linked to increased ASD odds.

Psychiatric aspects of methylmercury poisoning [PDF]
Journal of Neurology, Neurosurgery & Psychiatry, 1974 Forty-three patients with methylmercury poisoning were studied; 74·4% showed some degree of depression. Their blood levels of mercury were higher than the average values for the whole group, and considerably higher than the blood levels of the non-depressed patients.

Methylmercury-Cholinesterase Interactions in Rats
Environmental Health Perspectives, 1975 The interaction of methylmercury hydroxide (MMH) and cholinesterases was studied in male and female rats. MMH administered subcutaneously in doses of 10 mg/kg for 2 days reduced the level of plasma cholinesterase (ButChE) by 68% in females and 47% in males while brain acetylcholinesterase (AChE) was unaffected.
