Abstract Sulphate (SO 4 2-) concentrations in freshwaters have increased globally over the
last decades even though a strong reduction in atmospheric sulphur (S) deposition has …

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

Mercury (Hg) methylation produces the neurotoxic, highly bioaccumulative methylmercury
(MeHg). The highly conserved nature of the recently identified Hg methylation genes hgcAB …

Oceanic environments and biotas were in a state of near-continuous perturbation during the
Early Triassic, the~ 5-million-year interval following the latest Permian mass extinction …

Considerable recent research has focused on methylmercury (MeHg) cycling within
estuarine and coastal marine environments. Because MeHg represents a potent neurotoxin …

The concentration of total dissolved mercury (Hg T) in surface and groundwater resources in
the coastal parts of Urmia aquifer (NW of Iran) was investigated to identify the possible …

Mercury speciation, controls on methylmercury (MeHg) production, and bed sediment− pore
water partitioning of total Hg (THg) and MeHg were examined in bed sediment from eight …

Our review of the literature showed that since the beginning of the socio-economic
transformation in Poland in the 1990s, the downward trend in Hg emissions and its …

In a detailed study of the biogeochemical factors affecting the methylation of mercury in a
Chesapeake Bay salt marsh, we examined relationships between mercury methylation and …

Methylmercury (MeHg) concentration and production rates were studied in bottom
sediments along the mainstem of Chesapeake Bay and on the adjoining continental shelf …
