Organic compounds of mercury tend to be much more toxic than either the elemental form or the salts. These compounds have been implicated in causing brain and liver damage. The most dangerous mercury compound, dimethylmercury, is so toxic that even a few microliters spilled on the skin, or even on a latex glove, can cause death. [36] [37]
While all mercury compounds are toxic, organomercury compounds are especially dangerous because they are more mobile. Methyl mercury and related compounds are thought to bind to the sulfur of cysteinyl residues in proteins. [28] A 92-year-old Caucasian man (right) with pigmentary changes had used nose drops containing silver for many years.
Certain ethnic groups, as well as young children, are more likely to suffer the effects of methyl mercury poisoning. In the United States, Wallace gathered data that indicated 16.9% of women who self-identify as Native American , Asian , Pacific Islander , or multiracial exceed the recommended reference dose of mercury.

It is also used to calibrate NMR instruments for detection of mercury (δ 0 ppm for 199 Hg NMR), although diethylmercury and less toxic mercury salts are now preferred. [ 8 ] [ 9 ] [ 10 ] Around 1960, Phil Pomerantz, a man working at the Bureau of Naval Weapons , suggested that dimethylmercury be used as a fuel mix with red fuming nitric acid ...
Mercury can enter seas and the open ocean as a result of the down stream movement and re-deposition of contaminated sediments from urban estuaries. [12] For example, high total Hg content up to 5 mg/kg and averaging about 2 mg/kg occur in the surface sediments and sediment cores of the tidal River Mersey, UK, due to discharge from historical industries located along the banks of the tidal ...
Mercury in Pisces is the poet of Mercury transits — it feels everything but struggles to articulate it, leaving us lost in the sensation without the right words. So, if conversations feel deeper ...
The toxic effects of arsenic, mercury and lead were known to the ancients but methodical studies of the overall toxicity of heavy metals appear to date from only 1868. In that year, Wanklyn and Chapman speculated on the adverse effects of the heavy metals "arsenic, lead, copper, zinc, iron and manganese" in drinking water. They noted an ...
Mercury is the fastest-moving planet in the solar system – and it goes retrograde more often than any other planet. You’ll start to feel the energy take effect during the pre-shadow period ...
