Mercury (Hg) is ubiquitary, naturally enriched in volcanic regions, and has wide applications
in science, industry, and agriculture. Recently, the increasing awareness of Hg toxicity has …

The environmental cycling of mercury (Hg) can be affected by natural and anthropogenic
perturbations. Of particular concern is how these disruptions increase mobilization of Hg …

Microbial mercury (Hg) methylation transforms a toxic trace metal into the highly
bioaccumulated neurotoxin methylmercury (MeHg). The lack of a genetic marker for …

Methylmercury is a potent neurotoxin produced in natural environments from inorganic
mercury by anaerobic bacteria. However, until now the genes and proteins involved have …

Mercury is one of the most hazardous contaminants that may be present in the aquatic
environment, but its ecological and toxicological effects are strongly dependent on the …

Bacterial resistance to inorganic and organic mercury compounds (HgR) is one of the most
widely observed phenotypes in eubacteria. Loci conferring HgR in Gram-positive or Gram …

In Walden, Thoreau1 noted that “the largest pond is as sensitive to atmospheric changes as
the globule of mercury in its tube”. Here, we consider the modern understanding of the …

Mercury (Hg) is a natural and widespread trace metal, but is considered a priority pollutant,
particularly its organic form methylmercury (MMHg), because of human's exposure to MMHg …

Although mercury (Hg) is toxic at all valence states, organic Hg, especially
monomethylmercury (MeHg, CH3Hg+, methylmercury), is more toxic than inorganic Hg (Hg …
