Methylmercury Biosorption Activity by Methylmercury-resistant Lactic Acid Bacteria Isolated From West Sekotong, Indonesia [PDF]

, 2017
Methylmercury has been generally known as a toxic heavy metal for both human and environment. Bacterial-based bioremediation of heavy metal is suggested as an ecofriendly and low-cost bioremediation process.

A computational approach to seeking methylmercury(II) thiolate calix[4]arene hosts for both octasulfur and organosulfur compounds as guests

, 2001
Calculations have been carried out on the conformational preferences of calix[4]arene thiols and their methylmercury(II) derivatives. Calculations have also been carried out on host–guest combinations of methylmercury(II) ethanethiolate calix[4]arenes ...

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.

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.
