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 …

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 …

Human exposure to monomethylmercury (CH3Hg), a potent neurotoxin, is principally
through the consumption of seafood. The formation of CH3Hg and its bioaccumulation in …

Methylation of inorganic mercury in the aquatic environment has been considered to be
largely the result of biological processes, primarily involving sulfate-reducing bacteria …

With increasing input of neurotoxic mercury to environments as a result of anthropogenic
activity, it has become imperative to examine how mercury may enter biotic systems through …

Monomethylmercury (CH3Hg) is the only form of mercury (Hg) known to biomagnify in food
webs. Here we investigate factors driving methylated mercury [MeHg= CH3Hg+(CH3) 2Hg)] …

A method was developed to measure mercury methylation and demethylation rate constants
simultaneously in aquatic samples. Solutions containing stable isotope tracers of 199Hg2+ …

The curious phenomenon of similar levels of methylmercury (MeHg) accumulation in fish
from contaminated and pristine environments may be explained by the observation that the …

Methylmercury (MeHg) is the only species of mercury (Hg) to biomagnify in aquatic food-
webs to levels that are a widespread concern for human and ecological health. Here we …

Environmental mercury methylation appears modulated by sulfide concentrations, possibly
via changes in mercury availability to sulfate reducing bacteria, the major agents of this …
