Lithium sulfide is the inorganic compound with the formula Li2S.

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).

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

China dominates the global market simply because it has fairly abundant rare earth ores close to the surface.

Faced with severe supply constraints, Asian economies are increasingly tapping other continents fossil fuels, mineral ores, and timber.

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.

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.

He described many minerals and ores both from local mines such as those at Laurium near Athens, and further afield.

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

Smuggling of the conflict minerals, coltan and cassiterite (ores of tantalum and tin, respectively), has helped fuel the war in the Eastern Congo.

Like other rare earths, this element is never found as a free element in nature but is found bound in monazite sand ores.

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).

OXFORD In the coming decade, extraction of oil, gas, and mineral ores will constitute by far the most important economic opportunity in Africa s history.

Rare earth ores in southern China all except for those in Inner Mongolia contain radioactive substances that pose significant threats to human health and the environment.

Indeed, rare earth elements are rare only in the sense that they are distributed in small quantities and must be extracted from ores, a time consuming process.

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.

NEW DELHI Competition for strategic natural resources including water, mineral ores, and fossil fuels has always played a significant role in shaping the terms of the international economic and political order.

Five years from now, this is what I hope happens to me I'm taken back to the boat, I'm given a gas mask 80 parts per million hydrogen sulfide.

You're in an accident. 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.

So, it was interesting for us when we applied hydrogen sulfide to a mouse when it was also cold because what happened is the core temperature of the mouse got cold.

Similarly, countries can import fossil fuels, mineral ores, and resources from the biosphere like fish and timber but they cannot import water, which is essentially local, on a large scale and on a prolonged much less permanent basis.

And so, we wanted to find out might we be able to use hydrogen sulfide in the presence of cold, and we wanted to see whether we could reproduce this skier in a mammal.

Air samples taken from inside an unopened sarcophagus through a drilled hole showed high levels of ammonia, formaldehyde and hydrogen sulfide these gases are all toxic, but are easily detected by their strong odours.

Sulfur water is a condition where the running water contains a high amount of hydrogen sulfide gas that escapes into the air when the plumbing line is opened, giving a distinct rotten egg smell.

We draw from stocks of non renewable natural resources (for example, oil and metal ores), and we deteriorate or modify the quality of other resources (for example, water and arable land) by imposing on them a rhythm of exploitation superior to their capacity for regeneration.

So, these are the thought leaders in trauma medicine all over the world saying this is true, so it seems that exposure to hydrogen sulfide decreases damage that you receive from being exposed to otherwise lethal low oxygen.

Asteroid strikes get all the coverage, but Medea Hypothesis author Peter Ward argues that most of Earth's mass extinctions were caused by lowly bacteria. The culprit, a poison called hydrogen sulfide, may have an interesting application in medicine.

There is tremendous amounts of hydrogen sulfide coming into this cave from volcanic sources and from the breakdown of evaporite minerals below the carbonates in which this cave is formed and it is a completely hostile environment for us.

It turns purple from the presence of numerous microbes which have to have sunlight and have to have hydrogen sulfide, and we can detect their presence today we can see them but we can also detect their presence in the past.

Am I understanding you right, that what you're saying here is that we have in our own bodies a biochemical response to hydrogen sulfide that in your mind proves that there have been past mass extinctions due to climate change?

And so we thought, like in a game of musical chairs, might we be able to give a person some hydrogen sulfide, and might it be able to occupy that place like in a game of musical chairs where oxygen might bind?

In one model of heart attack, animals given hydrogen sulfide showed a 70 percent reduction in heart damage compared to those who got the standard of care that you and I would receive if we were to have a heart attack here today.

In fact, in chemical accidents, hydrogen sulfide is known to if you breathe too much of it, you collapse to the ground, you appear dead, but if you were brought out into room air, you can be reanimated without harm, if they do that quickly.

If you give mice hydrogen sulfide, you can lower their demand for oxygen, and you can put them into oxygen concentrations that are as low as 5,000 feet above the top of Mt. Everest, and they can sit there for hours, and there's no problem.

And in an enormous 40 page paper in German he says, at one point my wife is German and she translated it for me and at one point he says, ganz widerlich Geruch, an absolutely repulsive smell, which is good. Reminiscent of hydrogen sulfide.

And this company, the first thing it did was make a liquid formulation of hydrogen sulfide an injectable form that we could put in and send it out to physician scientists all over the world who work on models of critical care medicine, and the results are incredibly positive.

This led Lee Kump, and others from Penn State and my group, to propose what I call the Kump Hypothesis many of the mass extinctions were caused by lowering oxygen, by high CO2. And the worst effect of global warming, it turns out hydrogen sulfide being produced out of the oceans.
