Elemental phosphorus is prepared by the reduction of calcium phosphate, Ca3(P04)o, with coke in the presence of sand, SiO>. The products are phosphorus, calcium silicate, CaSiOa, and carbon monoxide.

Factors that can predispose patients to developing metabolic bone disease include deficiencies of phosphorus, calcium, and vitamin D vitamin D and/or aluminum toxicity amino acids and hypertonic dextrose infusions chronic metabolic acidosis corticosteroid therapy and lack of mobility.35,39 Calcium deficiency (due to decreased intake or increased urinary excretion) is one of the major causes of metabolic bone disease in patients receiving PN. Provide adequate calcium and phosphate with PN to improve bone mineralization and help to prevent metabolic bone disease. Administration of amino acids and chronic metabolic acidosis also appear to play an important role. Provide adequate amounts of acetate in PN admixtures to maintain acid-base balance. 

Pesticides may change the soil s element content. Some pesticides may increase plants micro- and macroelement content, such as nitrogen, phosphorus, calcium, potassium, magnesium, manganese, iron, copper, barium, aluminum, strontium and zinc, whereas others decrease these or other elements. Pesticides may cause ammoniac compounds to accumulate in the soil. Dimethoate and fluometuron increase nitrates in the soil, while DDT, carbaryl and HCH sharply decrease them. When prometrin was used, soil nitrate content decreased by 30-40% [3]. 

Fig. 16.4 Multiple linear model containing phosphorus, calcium and iron contents of the leaves correlated significantly with the polyphenol contents of fruit. Organic (filled symbols) and conventional fruits (open symbols) did not differ significantly in their average polyphenol contents however, trees with a low leaf nutrient status showed a lower polyphenol contents in fruit (R2 = 0.64). Circles = cultivar Glockenapfel , squares = cultivar Idared area between the curves = space where 95% of the modelled values can be expected.

Calcitonin is a polypeptide hormone that (along with PTH and the vitamin D derivative, 1,25-dihydroxycholecalciferol) plays a central role in regulating serum ionized calcium (Ca2+) and inorganic phosphate (Pi) levels. The adult human body contains up to 2 kg of calcium, of which 98 per cent is present in the skeleton (i.e. bone). Up to 85 per cent of the 1 kg of phosphorus present in the body is also found in the skeleton (the so-called mineral fraction of bone is largely composed of Ca3(P04)2, which acts as a body reservoir for both calcium and phosphorus). Calcium concentrations in human serum approximate to 0.1 mg ml-1 and are regulated very tightly (serum phosphate levels are more variable). 

The K/DOQI guidelines provide desired ranges of calcium, phosphorus, calcium-phosphorus product, and intact PTH based on the stage of CKD (Table 76-2). Measurements should be repeated every 12 months for stage 3, every 3 months for stage 4, and more frequently for stage 5. 

Table VII shows the calcium balance of zinc-fed and non-zinc-fed rats supplemented with 0.8% calcium and/or phosphorus. Marked increases in fecal calcium and corresponding decreases in apparent calcium retentions in the zinc-fed rats could be reversed with calcium supplementation. Phosphorus supplements appeared to be associated with increases in calcium retention in the absence of zinc, but decreases in calcium retention in the presence of zinc without calcium supplementation. Decreases in fecal calcium were noted in animals fed calcium supplements in the presence of phosphorus or zinc. High levels of zinc were associated with increases in fecal calcium excretion in the absence of extra calcium or in the presence of extra phosphorus. Calcium supplementation was generally associated with a decrease in the urinary excretion of calcium, while zinc and phosphorus supplements were generally associated with an increase in urinary calcium excretion.

Marggraf noticed that, when he dissolved the earth from alum in nitric acid, evaporated the solution, and calcined the residue, he merely regenerated the earth but obtained no Balduin s phosphorus (calcium nitrate). He realized, therefore, that the earth in alum must be different from that in chalk or limestone. He also demonstrated the presence of alumina in clay and in roofing slate (74). 

The data obtained have shown that l-(chloromethyl)silatrane produces a favourable effect on the physiological processes in the organism of fowl. It increases the viability, stimulates the function of haemopoiesis thus raising the number of erythrocytes and the amount of haemoglobin. Administration of 1-(chloromethyl)silatrane stimulates metabolic reactions in the organism thus increasing the metabolism of protein, lipids, carbohydrates and phosphorus-calcium.

Calcium, Magnesium and Phosphorus. Calcium and magnesium are the two major divalent cations of citrus fruit, but both occur in relatively low amounts in the juices ranging between 6-15 mg/100 ml (74). The contribution of citrus juices for these two mineral nutrients would only be 2-3 percent U.S. RDA per a serving of 177 ml (6 fl oz). However, when calculated on the basis of caloric intake, citrus juices provide all these three nutrients (phosphorus, calcium and magnesium) near or above their caloric contributions. 

Cellulose. Fiber components differ in their ability to bind to bile (41), the primary route of excretion of manganese (9). Cellulose, the most abundant natural fiber, has been studied for its potential effects on bile and lipid metabolism (42). It is naturally present in high fiber diets and is also commonly added to many commercially-produced food products. Previous studies have shown cellulose to decrease intestinal uptake of a variety of minerals, including zinc, phosphorus, calcium, magnesium, and iron (32,43,44). In many cases, however, the effect of cellulose has not been considered to be anti-nutritional (32). It has been generally believed that cellulose has a lower binding affinity for minerals than other constituents of dietary fiber (33,45). 

Kidney disease can be associated with a decreased ability to clear phosphorus calcium levels in the blood become low and can lead to a loss of calcium from the bones. 

Terra firme forests growing on Oxisols/ Ultisols seem to be primarily limited by phosphorus (Vitousek 1984, Vitousek and Sanford 1986, Cuevas and Medina 1986, Cuevas and Medina 1988), while at the same time being tolerant of high soil concentrations of mobile aluminum (Sprick 1979, Sobrado and Medina 1980). Cuevas and Medina (1988) showed that terra firme forests can also be limited by calcium and magnesium, which corroborated the hypothesis of Furch and Klinge (1989) who measured low Ca and Mg contents in biotic and abiotic compartments in terra firme forests of Amazonia. Plant adaptation to these conditions requires highly efficient uptake and/or utilization of nutrients, especially phosphorus, calcium and magnesium (Marschner 1995). 

Incomplete refining that leaves high levels of phosphorus, calcium, and magnesium... 

Although a number of unique elements, including phosphorus, calcium, potassium, iron, and zinc, are present to some extent, only iron is present in sufficient quantities (greater than 1%) and has high enough... 

Serum sodium, potassium, chloride, and bicarbonate values were all within the normal range in a series of 44 patients studied by Reinberg et al. (R6). Also, according to Sidi et al. (S12), serum phosphorus, calcium, and magnesium are normal. Zinc has already been discussed, and Molokhia and Portnoy (M15) will undoubtedly soon have comparison values of copper and manganese in the serum of psoriatics versus normals.

A total of 24 minerals (essentials and nonessentials) have been reported so far in hazelnut varieties, of which 13 essential mineral content are summarized in Table 12.2 by various studies [ 11,14,23,24,214]. In addition to the data in Table 12.2, mineral content of various hazelnut varieties has also been reported by several researchers [9,15,16,25-27,215]. In general, potassium is the most abundant mineral, followed by phosphorus, calcium, and/or magnesium. Several studies have indicated that mineral composition of hazelnut is affected by variety, geographical origin, harvest year, climate, composition of soU, irrigation, use of fertilizer, and method of cultivation [15,24,26,28].
