Mercury is a potent neurotoxin for humans, particularly if the metal is in the form of
methylmercury. Mercury is widely distributed in aquatic ecosystems as a result of …

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 …

Although water constitutes 71% of the earth's surface, only 0.3% of it is available as fresh
water for human use. Moreover, the quality of fresh water in ground and surface systems is …

Anthropogenic activities have enriched mercury in the biosphere by at least a factor of three,
leading to increases in total mercury (Hg) in the surface ocean. However, the impacts on …

The Hg-methylating ability of dissimilatory iron-reducing bacteria in the genera Geobacter,
Desulfuromonas, and Shewanella was examined. All of the Geobacter and Desulfuromonas …

Fish harvested from the Pacific Ocean are a major contributor to human methylmercury
(MeHg) exposure. Limited oceanic mercury (Hg) data, particularly MeHg, has confounded …

The origin and composition of dissolved organic matter (DOM) in porewater of lake
sediments is intricate and decisive for fate of pollutants including mercury (Hg). While there …

The study evaluated the nutritional quality in muscle tissues of nine commercially important
marine fish species. And the concentrations of trace metals (ie As, Hg, Cu, Pb, Cr, Cd and …

Recent studies have shown that climate change is already having significant impacts on
many aspects of transport pathways, speciation and cycling of mercury within Arctic …

We propose the use of Desulfovibrio desulfuricans ND132 as a model species for
understanding the mechanism of microbial Hg methylation. Strain ND132 is an anaerobic …
