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 …

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

This review summarizes biogeochemical processes that operate on diel, or 24-h, time scales
in streams and the changes in aqueous chemistry that are associated with these processes …

It was discovered in 1995 that, during the spring time, unexpectedly low concentrations of
gaseous elemental mercury (GEM) occurred in the Arctic air. This was surprising for a …

The fate and transport of Hg species in natural aquatic environment are strongly affected by
photochemical transformation of Hg 0, Hg 2+, and MeHg. Migration of Hg is determined by …

This report assesses research on the interactions of UV radiation (280–400 nm) and global
climate change with global biogeochemical cycles at the Earth's surface. The effects of UV-B …

In natural environments, inorganic mercury (Hg 2+) can be converted to the neurotoxin
methylmercury (MeHg) mainly via the microbial Hg methylation process with anaerobic …

Complex and ever changing in its forms and functions, the element mercury follows a
convoluted course through the environment and up the food chain. The process is …

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

Photo-decomposition is among the most important mechanisms responsible for degrading
monomethylmercury (MMHg) in aquatic systems, but this process is not fully understood. We …
