Elevated tungsten

[Guest guest]

We just got back a toxic metals test (urine) that showed very

elevated tungsten being excreted. What are the implications for

tungsten and is it one of the later metals to come out before hitting

mercury? Thanks for any feedback.

If this is chelated it doesn't mean anything unless it is several times

the " red limit. "

If unchelated it might mean something. Tungsten interferes with

molybdenum, so it owuld mean use 2-3 mg (2000-3000 mcg) of Mo daily,

plus avoid xanthines, purines and sulfites.

HTH...

Because of its ability to produce hardness at high temperatures and

its high melting point (the second highest of any known element),

tungsten is used in many high-temperature applications.[11] These

include light bulb, cathode-ray tube, and vacuum tube filaments, as

well as heating elements and nozzles on rocket engines.[2] The high

melting point also makes tungsten suitable for aerospace and high

temperature uses which include electrical, heating, and welding

applications, notably in the gas tungsten arc welding process (also

called TIG welding). It is also used in electrodes, and in the emitter

tips of field emission electron-beam intruments, such as focused ion

beam (FIB) and electron microscopes. The metal is also used in X-ray

targets.

Tungsten chemical compounds are used in catalysts, inorganic pigments,

and tungsten disulfide high-temperature lubricants which are stable to

500 °C (930 °F). Tungsten carbide (W2C or WC), produced by heating

powdered tungsten with carbon, is one of the hardest carbides, with a

melting point of 2770 °C for WC and 2780 degrees C for W2C. WC is an

efficient electrical conductor, but W2C is not as efficient. Tungsten

carbide behaves in a manner very similar to that of unalloyed tungsten

and is resistant to chemical attack, although it reacts strongly with

chlorine to form tungsten hexachloride (WCl6).[1] Tungsten carbide is

used to make wear-resistant abrasives and cutters and knives for

drills, circular saws, milling and turning tools used by the

metalworking, woodworking, mining, petroleum and construction

industries. In these applications, tungsten carbide may be combined

with cobalt, coated with titanium nitride or coated with titanium

carbide.[1]

The hardness and density of tungsten find uses in heavy metal alloys

that are used in armament, heat sinks, and high density applications,

such as weights, counterweights, ballast keels for yachts and tail

ballast for commercial aircraftand as ballast in high level race cars

in series such as NASCAR and Formula 1. In armaments, tungsten,

usually alloyed with nickel and iron or cobalt to form heavy alloys,

is used in kinetic energy penetrators as an alternative to depleted

uranium. Tungsten may be used in cannon shells, grenades and missiles

to create super-sonic shrapnel. Darts may contain a high proportion of

tungsten, allowing their diameter to be smaller than those made of

other metals, and permitting tighter groupings. Fishing lures like the

Mormyshka and many fishing flies use tungsten bead heads to sink the

fly rapidly. Some types of strings for musical instruments are wound

with tungsten wire. Tungsten, which has a similar density to gold, is

sometimes used in jewelry (such as wedding bands) as an alternative to

gold or platinum.[2] Its hardness makes it ideal for rings that will

resist scratching, are hypoallergenic and will not need polishing.

This property is especially useful in designs with a brushed finish.[12]

In metal alloys, High speed steel contains tungsten; some tungsten

steels contain as much as 18% tungsten. Superalloys containing

tungsten are used in turbine blades and wear resistant parts and

coatings. Examples are Hastelloy and Stellite.

Tungsten powder is used as a filler material in plastic composites,

which are used as a nontoxic substitute for lead in bullets, shot, and

radiation shields.

Since this element's thermal expansion is similar to borosilicate

glass, it is used for making glass-to-metal seals.[6]

In electronics, tungsten is used as an interconnect material in

integrated circuits. Contact holes are etched in silicon dioxide

dielectric material, filled with tungsten and polished to form

connections to transistors. Typical contact holes can be as small as

65 nm.

In the radiopharmaceutical industry, tungsten is used extensively for

shielding. It is often employed when transporting individual FDG doses

(called 'pigs') - the high energy of fluorine-18 makes lead much less

effective.

The oxides are used in ceramic glazes and calcium/magnesium tungstates

are used widely in fluorescent lighting. Crystal tungstates are used

as scintillation detectors in nuclear physics and nuclear medicine.

Other salts that contain tungsten are used in the chemical and tanning

industries.[6] Tungsten 'bronzes' (so-called due to the colour of the

tungsten oxides) along with other compounds are used in paints.

- besides light bulbs, I don't know where to look for exposure.

This is what Andy has to say about dealing with the problem:

" Administering high amounts of molybdenum both helps accelerate clearance of

tungsten and also opposes its toxic effect (which is to interfere with the

body's use of molybdenum).

" Supportive therapy is to avoid high purine foods, sulfites and alcohol, and to

limit the intake of foods containing thiols and their precursors.

" Tungsten is believed to clear on its won without retention in any specific

organ, so chelation is seldom appropriate. " (HTI p.250)

Of course, he also says that finding the exposure is critical.

reference range on fecal metals is .09. my 4yo is 3.114. chronic

exposure or a lymes abberation? looks like he's moving all the evil

metals too (yeah) we may have a " tungsten " kitchen...but looking at

his thermos lunch containers...they go everywhere...ughh!

anyone have any ideas? cookware is all stainless...and we use plastic

because...break! and paper....squish!

thanks,

lisa

thank you!? wondering if the dishwasher is a culprit as well as his thermos jars

we use to pack all meals not at home and new?air system.? live a city block and

a half under a huge reservation so that's one expsosure that might be difficult

to limit.

down to?few foods and keeping my fingers crossed on navy beans...think that adds

some molydebun (sp) and ammonia poops are much better.? found an article on

tungsten/molydebun and colostria (which confirmed it was about the human body

for me!)...so we'll have to clean up and retest...also need to see what's

pulling the mercury...that was great to see!

thanks!!
