Selenium Tone

This is, what, selenium? tin

Black White with Selenium Tone This effect replicates traditional selenium chemical toning done in the darkroom.

Selenium deficiency in livestock has become an issue in recent years due to the lack of selenium in soil.

Polymetallic sulfide mining

Oxidation of hydrogen sulfide, sulfide, and elemental sulfur (S) to sulfate (SO42 ).

Reminiscent of hydrogen sulfide.

80 parts per million hydrogen sulfide.

Chlorium Oxide 13 Lead sulfide 3

It's filled with this toxic gas, hydrogen sulfide.

Now, hydrogen sulfide is curiously present in us.

I told you hydrogen sulfide is in us.

Hydrogen sulfide is very fatal to we humans.

Yttrium(III) sulfide (Y2S3) is an inorganic chemical compound.

In contrast, over exposure to selenium in the diet leads to a condition known as Selenosis.

Lithium sulfide is the inorganic compound with the formula Li2S.

We can easily go back to the hydrogen sulfide world.

It can also be produced directly using the Girdler sulfide process.

Oxidation of hydrogen sulfide produces elemental sulfur (S8), oxidation state 0.

In purple sulfur bacteria, hydrogen sulfide (H2S) is oxidized to sulfur (S).

We had these hydrogen sulfide oceans for a very great long period.

So if I have, let's say I wanted to take the example of, if this is Sn, this is selenium.

Dissimilative sulfur reduction in which elemental sulfur can be reduced to hydrogen sulfide.

We know hydrogen sulfide is erupting presently a few places on the planet.

Germanium disulfide or Germanium(IV) sulfide is the inorganic compound with the formula GeS2.

Stromeyerite is a sulfide mineral of copper and silver, with the chemical formula AgCuS.

Because there's no oxygen there, it's the largest reservoir of hydrogen sulfide on Earth.

They often use some of several laboratory methods for diagnosis of bad breath Halimeter a portable sulfide monitor used to test for levels of sulfur emissions (to be specific, hydrogen sulfide) in the mouth air.

Yeah, every single cell in us can produce minute quantities of hydrogen sulfide in great crises.

Acid gases carbon dioxide (CO2), hydrogen sulfide (H2S) and mercaptans such as methanethiol (CH3SH) and ethanethiol (C2H5SH).

There are microbes which, through their metabolism, produce hydrogen sulfide, and they do so in large amounts.

Most rare elements on Earth are not needed by life (exceptions being selenium and iodine), while a few common ones (aluminum and titanium) are not used.

Because there's no oxygen there, it's the largest reservoir of hydrogen sulfide on Earth. Shipwrecks are perfectly preserved.

Peter Ward Yeah, every single cell in us can produce minute quantities of hydrogen sulfide in great crises.

Desulfurization in which organic molecules containing sulfur can be desulfurized, producing hydrogen sulfide gas (H2S, oxidation state 2).

And the worst effect of global warming, it turns out hydrogen sulfide being produced out of the oceans.

And I should say that the concentrations of hydrogen sulfide required to get this benefit are low, incredibly low.

Studies focusing on the biological effects of selenium have brought greater attention to Sodium Selenate due to its regulatory role in the function of the PP2A phosphatase protein.

Now, the same mouse is given 80 parts per million hydrogen sulfide in this solid graph, and look what happens to its temperature.

Other compounds detected in volcanic gases are oxygen (meteoric), hydrogen chloride, hydrogen fluoride, hydrogen bromide, nitrogen oxide (NOx), sulfur hexafluoride, carbonyl sulfide, and organic compounds.

We also found out that we could subject animals to otherwise lethal blood loss, and we could save them if we gave them hydrogen sulfide.

And what you're seeing here is a cloud of densely packed, hydrogen sulfide rich water coming out of a volcanic axis on the sea floor.

You've got two choices you're going to die, or you're going to take the hydrogen sulfide and, say, 75 percent of you is saved, mentally.
