All Non-IgE Mediated Immune System Responses to Food, being slower acting, are classed as being Food Intolerances, a term which includes other types of slow reaction included a lack of necessary enzymes and toxicological responses etc. Of course, IgE and non-IgE immune responses can occur within the same patient to the same food type, but at slightly different times, i. Wikipedia defines Food Allergy according to three groups: IgA, IgG and IgM reactions Some of the latter two groups are hereditary genetic in nature, others are merely conditioned or acquired.
Chemistry in its element: End promo Chris Smith Hello - this week fertilisers, fire bombs, phossy jaw and food additives. Nina Notman Phosphorus is a non-metal that sits just below nitrogen in group 15 of the periodic table.
This element exists in several forms, of which white and red are the best known. White phosphorus is definitely the more exciting of the two. As it glows in the dark, is dangerously flammable in the air above 30 degrees, and is a deadly poison.
Red phosphorus however has none of these fascinating properties. So where did it all begin? Phosphorus was first made by Hennig Brandt in Hamburg in Germany in When he evaporated urine and heated the residue until it was red hot.
Glowing phosphorus vapour came off and he condensed it under water. And for more than years most phosphorus was made this way. This was until people realised that bone was a great source of phosphorus.
Bone can be dissolved in sulfuric acid to form phosphoric acid, which is then heated with charcoal to form white phosphorus.
White phosphorus has found a range of rather nasty applications in warfare. It was used in the 20th century in tracer bullets, fire bombs, and smoke grenades. The scattering of phosphorus fire bombs over cities in World War II caused widespread death and destruction.
In JulyHamburg was subject to several air raids in which 25, phosphorus bombs were dropped over vast areas of the city. This is rather ironically considering where phosphorus was first made.
Another group of warfare agents based on phosphorus are nerve gases such as sarin. Sarin is a fluorinated phosphonate that was used by Iraq against Iran in the early to mids. And was also released in a Tokyo subway inkilling 12 people and harming nearly a thousand others. White phosphorus has also found a wide range of other uses.
One of these was in phosphorus matches that were first sold in Stockton-on-Tees in the UK in This created a whole new industry of cheap lights - but at a terrible cost. Breathing in phosphorus vapour led to the industrial disease phossy jaw, which slowly ate away the jaw bone.
This condition particularly afflicted the girls who made phosphorus matches.What exactly are phosphates? Phosphates are chemical compounds containing phosphorus, a naturally occurring mineral, and oxygen, that are used in a wide variety of applications (e.g., cleaning and baking products).
Sometimes they include other minerals, such as calcium and sodium. Phosphates enter waterways from human and animal waste, phosphorus rich bedrock, laundry, cleaning, industrial effluents, and fertilizer runoff. These phosphates become detrimental when they over fertilize aquatic plants and cause stepped up eutrophication.
Eutrophication is the natural aging process of a body of water such as a bay or lake.
Sol–gel chemistry offers a flexible approach to obtaining a diverse range of materials. It allows differing chemistries to be achieved as well as offering the ability to produce a . It is the chlorine in municipal drinking water, sulphur in the concentrated protein of meat, fish, eggs and hard cheese, and phosphorous in meat and soft drinks that makes these foods so acidic.
In general, a more vegetarian diet is more alkaline. It is a question of balance, and at present the balance is tilted too heavily in the direction of acid foods.
Phosphite or Phosphoric Acid vs. Phosphorous Acid • One is the source for a fertilizer, the other is a source for a fertilizer and a fungicide? • Phosphate fertilizers are generally made from phosphoric acid (H3PO4), while phosphites are made from .
Most people might think of a green spirulina drink or a "nutrition bar" when they hear the word "superfood". However, it turns out that liver (from grass-fed animals) is nature's most potent superfood. So throw away your soy protein bars and noni juice and eat some liver!
