The toxicity of mercury arises from the very high affinity of the soft Hg atom for sulfhydryl (—SH) groups in enzymes. Simple mercury-sulfur compounds have been studied as potential analogs of natural systems.

The Hg atoms are most commonly four-coordinated, as in [Hg 2 (SMe) 6] Mercury poisoning was a serious concern even from early days. The urine and faeces are the main excretory pathways of elemental mercury and inorganic mercury compounds in humans, with an absorbed dose half-life of approximately 1–2 months (Clarkson, ).

After a short-term high-level mercury exposure in humans, urinary excretion accounts for. A new page on the road book of inorganic mercury in fish body - tissue distribution and elimination following waterborne exposure and post-exposure periods.

Mercury poisoning affected my ability to focus throughout my school years, so academic potential was never released.

I eventually found dentists who took out the amalgam (during the 80’s and 90’s this was so difficult) but though chelation was never mentioned, I did find immediate benefits.

Mercury vapor emitted into the atmosphere is eventually oxidized into inorganic forms, which are water-soluble. It is then distributed worldwide by rainfall. Most of the inorganic mercury settles in the sediment, where it reacts with sulfate to form insoluble precipitate.

A small percentage is methylated by bacteria and becomes bioavailable. Inorganic mercury is usually white, except for cinnabar, which is red. Inorganic mercury can enter the body through mouth and skin from products such a disinfectants and fungicides.

Inorganic mercury compounds are frequently found in school science labs. RISK: Inorganic mercury is the least toxic of the three forms of mercury. It can damage the. Mercury (Hg) and its derivatives pose a serious threat to the environment and human health because of their durability, easy transference, and high biological accumulation.

Thus, the development of methods for selective and sensitive determination of Hg2+ is very important to understand its distribution and implement more detailed toxicological by: Unlike inorganic mercury, MeHg is well-absorbed (~95%) from the gastrointestinal tract; once absorbed, MeHg distributes extensively to tissues such as kidney, liver, and brain, with a systemic half-life of weeks.

Inorganic mercury is poorly absorbed and is not methylated by human metabolic enzymes, thus MeHg must be consumed to occur in humans. Inorganic Ventures provides an interactive periodic table.
