It's not different, it's the same stuff calcium carbonate, calcium carbonate.

There's consequences for carbonate organisms.

And they said, calcium carbonate.

Ammonium hydrosulphide, benzidine, superoxide of hydrogen.

And they can pull calcium out of the environment, put down a layer of calcium and then carbonate, calcium and carbonate.

The main framework material of coral reefs is calcium carbonate.

But it's not just the carbonate producers that are affected.

Other inorganic nitrate salts may replace part of the ammonium nitrate.

And I said, that's what this is this is calcium carbonate.

It then spread to a huge stockpile 800 tonnes of ammonium nitrate fertilizer.

Ammonium nitrate can be purchased easily and cheaply in most countries as fertilizer.

When you evaporate seawater, the first thing to crystallize out is calcium carbonate.

Oh, by the way, just in case you weren't already guessing, it's calcium carbonate.

There are many organisms that build their shells out of calcium carbonate plants and animals both.

Besides legitimate purchases, significant quantities of ammonium nitrate are occasionally stolen from dealers and other storage sites.

To this effect, the United Kingdom adopted the Ammonium Nitrate Materials (High Nitrogen Content) Safety Regulations in 2003.

Here, we've got a protocell to extract carbon dioxide out of the atmosphere and turn it into carbonate.

We can analyze the carbonate that makes up the coral, and there's a whole bunch of things we can do.

This abalone shell is a biocomposite material that's 98 percent by mass calcium carbonate and two percent by mass protein.

And that builds up on the evaporators and that's what that image on the left is gradually getting encrusted with the calcium carbonate.

And why? Because the lowly abalone is able to lay down the calcium carbonate crystals in layers, making this beautiful, iridescent mother of pearl.

These regulations establish certifiable standards and control mechanisms on ammonium nitrate based products and compounds, particularly those containing more than 28 per cent by weight of nitrogen.

The organism has the relatively rare capability of removing nitrogen from the atmosphere, converting it to ammonium, retaining some for its own nourishment and releasing the rest.

Ammonium nitrate has been used by terrorists in the composition of bombs for numerous attacks, including the Oklahoma City bombing of 1995 and the Istanbul bombings of November 2003.

The mixture for emulsions typically has the following composition 60 85 ammonium nitrate, 5 30 water, 2 8 fuel, 0.5 4 emulsifier agent, 0 10 soluble flame suppressants, and trace additives.

The wastewater is now trucked off in tanks and dumped on Palestinian fields.22 The water contains high levels of calcium carbonate, increasing the already high pH level of the land.

Al Qaida supporters arrested in the United Kingdom in March 2004 on suspicion of planning a massive explosion in central London were found to have acquired and stored over half a ton of ammonium nitrate.

This entry applies to non sensitized emulsions, suspensions and gels consisting primarily of a mixture of ammonium nitrate and fuel, intended to produce a Type E blasting explosive only after further processing prior to use.

For example, the Colombian authorities were issuing authorizations for individual transactions of butyl acetate, ethyl acetate, isopropyl acetate, hexane solvent no. 1 and 2, chloroform, methanol, diacetone alcohol, isopropyl alcohol, butanol thinner, sodium carbonate, ammonia and manganese dioxide.

Despite the difficulties of effective regulation of dual use goods, the Monitoring Team believes there is scope to introduce new measures that would limit the ability of Al Qaida and the Taliban to use commercial or improvised explosives, such as ammonium nitrate.

The mixture for suspensions and gels typically has the following composition 60 85 ammonium nitrate, 0 5 sodium or potassium perchlorate, 0 17 hexamine nitrate or monomethylamine nitrate, 5 30 water, 2 15 fuel, 0.5 4 thickening agent, 0 10 soluble flame suppressants, and trace additives.

In view of the threat posed by improvised explosives and the potential to reduce the threat through national regulatory mechanisms, the Team recommends that the Council urge States to share established legislative best practice on the matter, and encourage States that have not already done so to introduce safety regulations governing the manufacture and sale of ammonium nitrate based products with a high nitrogen content.
