:A lot of that information was there a while back, but there was a series of vandalism that removed it. I don't feel comfortable enough in my Wiki skills to try to reinstate it, but someone else is welcome to try. It's at "Revision as of 17:12, 6 December 2007 (edit) (undo)84.55.192.114 (talk) (→Uses)Next edit → " This location might be plus or minus one edit maybe, so much going on it's hard to tell. You can certainly see it earlier in the year about the time I added a paragraph on food use (Sept 2007) but there was also mining, fertilizer, etc. info there Sigh NNNs (talk) 15:13, 10 April 2009 (UTC)

message: The Geochemistry of phosphates paragraph contains a bit about the distribution of rock phosphate over the world. This part needs a rewrite. It focuses mainly on the USA, and is incomplete in it's description the rest of the world.
According to this  by the U.S. Geological Survey, China is the second largest producer in de World, but China is not even mentioned. 83.163.181.226 (talk) 12:49, 18 October 2009 (UTC)

message: ...there should be mention of phosphate mining's ecological destruction, especially in small south pacific islands which have been devastated.
It is shocking that no mention is made of the flouride effusions of the phosphate extraction process.  See here: https://www.youtube.com/watch?annotation_id=annotation_658443&feature=iv&list=UL&src_vid=2YDeMaR38uE&v=LEZ15m-D_n8   Phosphate mining is reportedly the primary source of the hydroflourosalycic acid dumped in municipal water supplies, but otherwise deemed a hazardous waste product by the EPA.

message: Consider adding:
In a phosphate group, a phosphorous atom is bonded to four oxygen atoms; one oxygen is bonded to the carbon skeleton; two oxygens carry negative charges.  The phosphate group (—OPO32-) is an ionized form of a phosphoric acid group (—OPO3H2; note the two hydrogens). Organic phosphates, unlike the hydrogenphosphate ion HPO42−, which is the conjugate base of H2PO4−, typically do not express Hydrogen before the Phosphate; —OPO32- reveals that the anterior oxygen is bound to the carbon skeleton.

thread_title: Phosphate expressed as a functional group

message: I was looking for information on the old-timey concoction that they used to call a "phosphate".  I'm frankly not sure if there is any actual phosphate in a phosphate (there probably was, as phosphoric acid, to add a "tart" flavor to the drink).  I got the following from the "Free Online Dictionary":
3. A soda fountain drink made by blending carbonated water with flavored syrup.
It doesn't mention phosphate as an ingredient, but I found a number of references to Coke and Pepsi as being high in phosphates (read The health effects of drinking soda - quotes from the experts).  I also found on this page that "Coke and other soft drinks are acidified with phosphoric acid[...]"
Of course, this goes on the assumption that a "phosphate" was a type of soft drink similar to what we call soft drinks or soda pop today.  The only fact that I am sure of is that it was something created at a "soda fountain" (which I believe was also often the local pharmacy).  I have a bunch of disparate information, but nothing solid that I could use to update the Phosphate entry or start a new derivation.  
I'm hoping this will spark someone with real knowledge to do so.
Some soda fountains of the fifties kept a bottle of "phosphate" near the spot where soft drinks were concocted, and a customer could order, for example, a cherry coke with phosphate.  One drop would add some tartness; two drops resulted in a major pucker.  Cherry cokes were a prime candidate for this treatment as the cherry flavoring lent an abundance of sweetness.  The phosphate, whatever it was, was a clear thin liquid.
:NOTE: A phosphate may also be a soda fountain drink, composed of mineral water and a flavored syrup. I suggest to remove this sentence in the lead. From my understanding this article is about the chemical compund, not a soda drink. If that drink is really worth mentioning in any encyclopedia (never heard of it before) it might get its own entry. Any objections? --Splette  Talk 17:27, 31 August 2006 (UTC)
replies: text: While I do not object to that removal, I have heard of phosphate drinks.  I have read in several books old folks speaking of buying phosphates at the drug store. Dictionary.com has several definitions that refer to the drink: 
a carbonated drink of water and fruit syrup containing a little phosphoric acid.
  Basically, it's a soda.  Prometheus-X303- 00:21, 4 March 2007 (UTC)
replies: text: See phosphate soda. Cherry phosphate, used a mixed salt that incorporated the hydrogenated phosphate ion as its source of phosphoric acid. In modern times this was superceded by other acidifiers like citric acid. For future reference, you're likely to get a more comprehensive aswer from the science reference desk.

thread_title:  Phosphates - The Drink 

message: Is it really necessary to add phosphates into food?
Depends on your definition of necessary. Is it necessary to have fluffy pancakes, refrigerated biscuits or lunchmeat that doesn't turn into shoe leather? (That's a matter of opinion) Can you substitute it with other nonphosphate compounds that may or may not be as effective or economical? (Possibly)Is it necessary to add it nutritionally? (Probably get enough from a normal diet, but would have to check before stating that as a fact)

message: Refer from Buffering agent, which said: "Buffering agents in humans, functioning in acid-base homeostasis, are extracellular agents (e.g., bicarbonate, ammonia) as well as intracellular agents (including proteins and phosphate)." The important thing is, what kind of phosphate in the cell of human body that work as a buffer? I think this Phosphate article should be expanded to cover that kind of example...

The third last paragraph mentions the role of phosphate as a catalyst and buffer, before it participates in the creation of ribonucleotides (RNA).  
We should work this new information into the article (somehow).

message: Here in Germany, the use of uranium-contaminated standard phosphate fertilizers in farming has been linked to significantly raised uranium levels in the drinking water of some areas. It has lead to recommendations to use bottled water for baby food, instead of tap water. If anybody  knows of similar research in other countries, it might be recommendable to give this an extra paragraph in the article.

thread_title:  Uranium contamination of fertilizer phosphate 

message: Inexpertly, the central Phosphorous (P) atom must lose an electron (P+), so as to have a 4-electron valence shell, like carbon (which can also form four tetrahedral bonds).  Then, each of the four Oxygen (O) atoms must gain an electron (O-), so as to have a 7-electron valence shell, like Fluorine (which can also form single bonds).  Thus, is not the quantum structure of Phosphate (P+)(O-)4 ? 66.235.38.214 (talk) 06:16, 4 October 2012 (UTC)
