Pharmacology

Biological Half-Life · 2 items

The mean plasma half-life of aluminum after iv admin in dogs is approx 4.5 hr. /Aluminum/

The shorter half-life for the urinary elimination of aluminum was about 8 hr. /Aluminum/

Metabolism/Metabolites · 1 item

Aluminum is poorly absorbed following either oral or inhalation exposure and is essentially not absorbed dermally. The bioavailability of aluminum is strongly influenced by the aluminum compound and the presence of dietary constituents which can complex with aluminum and enhance or inhibit its absorption. Aluminum binds to various ligands in the blood and distributes to every organ, with highest concentrations found in bone and lung tissues. In living organisms, aluminum is believed to exist in four different forms: as free ions, as low-molecular-weight complexes, as physically bound macromolecular complexes, and as covalently bound macromolecular complexes. Absorbed aluminum is excreted principally in the urine and, to a lesser extent, in the bile, while unabsorbed aluminum is excreted in the faeces. (L739)

Absorption, Distribution and Excretion · 5 items

It was calculated that a dialysate aluminum concn of 0.2-1.0 mg/l (a concn readily found in many water supplies) would result in the direct transfer of aluminum into the blood of 3-16 mg for each dialysis treatment or 42-211 mg/mo. /Aluminum/

A given oral dose of aluminum results in significantly higher serum and tissue levels of the metal in nephrectomized rats than in intact controls in spite of the fact that only minimal amounts of aluminum are normally excreted in the urine. /Aluminum/

It was found that 70-90% of total aluminum bound to plasma proteins (60-70% to a high molecular weight protein and 10-20% to albumin while only 10-30% was unbound). This high affinity of aluminum for plasma proteins strongly suggests high levels of binding of aluminum to a variety of tissue proteins. /Aluminum/

It was shown that the uptake of aluminum into the blood during renal dialysis was due to the extensive binding of aluminum to plasma proteins leaving very little aluminum in the non-bound state in plasma. Thus, the plasma proteins served as a trap for accumulating the metal. It was shown that the component of plasma protein that binds aluminum is saturable. Consistent with this ... is the fact that, during dialysis with aluminum containing dialysate, plasma aluminum levels reach a plateau. /Aluminum/

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

Interactions · 3 items

In a case study of patients on long-term dialysis, systemic aluminum absorption with concurrent oral citrate (as an alkalinizing agent) and aluminum containing phosphate binder (eg, aluminum hydroxide or carbonate) was significantly increased. Based on the proposed mechanism and pharmacologic similarity, an interaction may be expected to occur between citric acid and other aluminum salts (eg, aluminum phosphate, aluminum glycinate, attapulgite, dihydroxyaluminum, kaolin, magaldrate). It has been shown that following concurrent administration of citric acid (from lemon juice) and aluminum hydroxide there is an increase in serum levels of a nonionized aluminum citrate complex, which is postulated to easily pass the gastrointestinal barrier. Simultaneous administration of citric acid and aluminum hydroxide should be avoided since significant systemic absorption of aluminum may occur. This may be of additional concern in patients on long-term dialysis or with impaired renal function. /Aluminum salts/

... 25 Dialysis patients that experienced accidental exposure to aluminum and parathyroid hormone /were examined/. At the same time as parathyroid hormone decreased, serum calcium increased. Based on this observation it has been suggested that aluminum is incorporated, instead of calcium, into the bone and that this leads to the osteomalacia characteristic of aluminum induced bone disease. Instead of being incorporated into osteoid bone tissue, calcium returns to the circulation which in turn inhibits the parathyroid hormone release from the parathyroid. In support of this hypothesis, ... a strong correlation /was found/ between bone aluminum content and the amount of bone occupied by unmineralized osteoid in humans. Experimental support for the hypothesis of calcium aluminum interactions has also been provided in studies on chicks. /Aluminum/

Groups of 120 Atlantic salmon fry (Salmo salar, 1 g mass) were kept in through flow tanks of water (pH 5) containing various concn of aluminum and silicic acid. The aluminum concn in all but the control tank (0.85 umol aluminum/l) were 6-7 umol/l, at acutely toxic levels. Silicon levels were 0.66 umol/l (control), 93.06, 24.89, 5.46, and 0.60 umol/l, corresponding to silicon:aluminum ratios of 13.0, 3.7, 0.9, and 0.1. Exchangeable aluminum, ie, aluminum retained on Amberlite, was 6.00, 5.00, 4.11, and 1.52 umol/l in test tanks, respectively. Fish were exposed for 96 hr, and the proportion of dead fish was recorded at 12 hr intervals. The whole experiment was run three times; data are from all runs combined. At a silicon:aluminum ratio of 13, acute toxicity of aluminum was eliminated and gill structures of the fish were normal. Percent survival versus time was higher for the higher silicon:aluminum ratio groups. Accumulation of aluminum by fish fell sharply as the exchangeable aluminum increased. Aluminum and silicon levels in fish were 0.44 and 0.01 (control), 0.40 and 0.54 (silicon:aluminum ratio of 13), 2.04 and 0.35 (silicon:aluminum ratio of 3.7), 2.49 and 0.33 (silicon:aluminum ratio of 0.9), 2.38 and 0.08 (silicon:aluminum ratio of 0.1) umol/g dry mass, respectively. /Aluminum/

Health Effects · 1 item

Aluminum targets the nervous system and causes decreased nervous system performance and is associated with altered function of the blood-brain barrier. The accumulation of aluminum in the body may cause bone or brain diseases. High levels of aluminum have been linked to Alzheimer's disease. A small percentage of people are allergic to aluminium and experience contact dermatitis, digestive disorders, vomiting or other symptoms upon contact or ingestion of products containing aluminium. (L739, L740)

Environmental Fate · 4 items

AQUATIC FATE: The adsorption of aluminum by fine particulates was studied in Whitray Beck, a hill stream in England. ... Uptake of aluminum by the particles increased with total aluminum , with pH, and with particle concentration, although the fraction of aluminum bound at a given pH and particle concentration decreased with total aluminum ... . /Total aluminum/

TERRESTRIAL FATE: Air dried, <2 mm fractions of 3 soil samples from The Netherlands and 1 from New Hampshire, were taken from the surface and subsurface horizons of two podzols (Haplorthods) and of a recent driftsand (Udipsamment). Duplicate samples of each emulsion soil horizon were leached ... with aqueous hydrogen chloride (pH 3.0). ... Charge balances of the leachates indicate that dissolved aluminum is present mainly as aquo-aluminum +3. Only in leachates of podzol Bhs horizons is a significant fraction (20-30%) of dissolved aluminum organically complexed. Dissolved aluminum concn are significantly correlated with the organic (tetrasodium pyrophosphate extractable) aluminum content of the soil sample. Mobility of aluminum in the Hubbard Brook soils is significantly lower than in the Dutch soils, because of higher soil solution pH values. /Aluminum cmpd/

TERRESTRIAL FATE: Albic and spodic soil horizons were sampled from old growth eastern white pine/mixed northern hardwoods. Adirondacks, and an ochric soil horizon was sampled from the Appalachian plateau of NY State. 21 Three horizon forest floor and 21 forest floor/mineral soil (field moist equivalent of 12.0 oven dry albic, spodic, or ochric mineral soil) columns were leached in triplicate with either 10 uM nitric acid (pH 5), 5 uM sulfuric acid (pH 5), 100 uM nitric acid (pH 4), 50 uM sulfuric acid (pH 4), 1000 uM nitric acid (pH 3), 500 uM sulfuric acid (pH 3), or distilled, deionized water (pH 5.7) control treatment). Nitric acid leached more aluminum than did sulfuric acid from forest floor/spodic soil columns. Increasing the nitric acid concn from pH 3-5 increased total aluminum concn in leachates from 0.70 to 0.85 mM, while increasing sulfuric acid had no effect. Addition of pH 3 sulfuric acid to forest floor/spodic columns raised leachate pH relative to pH 3 nitric acid and controls, and resulted in the lowest aluminum concn of all treatments in the first 3 of 4 sequential leachings. /Aluminum/

TERRESTRIAL FATE: Albic and spodic soil horizons were sampled from old growth eastern white pine/mixed northern hardwoods sites in the Adirondacks, and an ochric soil horizon was sampled from the Appalachian Plateau of NY State. 9 Three horizon forest floo, 9 mineral soil (field moist equivalent of 12.0 oven dry albic, spodic, or ochric mineral soil) and 9 forest floor/mineral soil columns were leached with 60 ml of (a) 10 mM ammonium nitrate (control), (b) 1.0 mM nitric acid in 10 mM ammonium nitrate (pH 3), and (c) 1.0 mM ammonium nitrate (pH 3) at the rate of 10 ml/h. The above procedure was repeated on each mineral soil without a forest floor, except leaching soln were 0.5 mM calcium nitrate or calcium sulfate, each in 10 mM ammonium nitrate. Adding 2 and 0.5 cmol sub c (H+)/kg to forest floor and mineral soils, respectively, simulated snowmelt additions. Total aluminum concn in leachates from forest floor/albic or forest floor/ochric columns were greater than the sum of concn in leachates from the forest floor and mineral horizon when leached separately. This positive synergistic behavior of the forest floor-mineral horizon sequences was also observed in the forest floor-spodic horizon sequence when leached with control soln, but the synergism was negative for both labile and non-labile aluminum when leached with the acids. Sulfuric acid leached less aluminum from the spodic horizon than did nitric acid, regardless of the presence of a forest floor, but nitric acid, sulfuric acid , and control soln leached similar concn of aluminum from the albic and ochric horizons. The forest floor effects on the mineral soil leachates were attributed to effects of calcium, sulfate, nitrate, and dissolved organic C leached from the forest floor to the mineral horizon since forest floor removed nearly all added H+. /Aluminum/

Toxicity Summary · 1 item

The main target organs of aluminum are the central nervous system and bone. Aluminum binds with dietary phosphorus and impairs gastrointestinal absorption of phosphorus. The decreased phosphate body burden results in osteomalacia (softening of the bones due to defective bone mineralization) and rickets. Aluminum's neurotoxicity is believed to involve several mechanisms. Changes in cytoskeletal protein functions as a results of altered phosphorylation, proteolysis, transport, and synthesis are believed to be one cause. Aluminum may induce neurobehavioral effects by affecting permeability of the blood-brain barrier, cholinergic activity, signal transduction pathways, lipid peroxidation, and impair neuronal glutamate nitric oxide-cyclic GMP pathway, as well as interfere with metabolism of essential trace elements because of similar coordination chemistries and consequent competitive interactions. It has been suggested that aluminum's interaction with estrogen receptors increases the expression of estrogen-related genes and thereby contributes to the progression of breast cancer (A235), but studies have not been able to establish a clear link between aluminum and increased risk of breast cancer (A15468). Certain aluminum salts induce immune responses by activating inflammasomes. (L739, A235, A236)

Human Toxicity Excerpts · 5 items

(SOLUTION) TOXIC; STRONG IRRITANT TO TISSUE.

IT IS KNOWN TO HAVE CAUSED INJURIES OF EYES SIMILAR TO THOSE CAUSED BY SODIUM HYDROXIDE. THE INJURIOUSNESS OF SOLUTIONS OF SODIUM ALUMINATE ARE PROPORTIONAL TO THEIR ALKALINITY.

Patients who had died with dialysis encephalopathy syndrome had brain gray matter aluminum levels that were 3 times higher (approximately 12 mg/kg dry weight) than those seen in patients who had been comparably dialyzed but did not have dialysis encephalopathy syndrome (approximately 4 mg/kg dry weight). Both of these groups were markedly higher than the 1 mg/kg dry weight level seen in controls. These data clearly indicate elevated brain levels of aluminum in dialyzed patients and emphasize the fact that only the highest levels of brain aluminum are associated with dialysis encephalopathy syndrome. /Aluminum/

X ray spectrometric evidence of aluminum accumulation in neurofibrillary tangle bearing neurons of human brains was reported. Quite in contrast to the extensive literature on aluminum in dialysis encephalopathy syndrome, there appears to be only a small amount of additional corroborating evidence for elevated brain levels of aluminum in Alzheimer's disease patients. ... Much of the argument for a role of aluminum in Alzheimer's disease has been built on the fact that in experimental animals, such as cat and rabbit, intracerebral injections of small amounts of aluminum result in neural degeneration which is characterized by the development of neurofibrillary tangles. ... Aluminum induced tangles in experimental animals are composed of single 10 nm filaments while those from Alzheimer's disease are paired, helically wound filaments. ... In spite of the apparent similarities in the two types of tangles, there are sufficient differences to warrant caution in interpreting that the tangles in humans are caused by aluminum as they are in experimental animals. /Aluminum/

Applications · 3 items

UsesSodium aluminate is used in the treatment of industrial and municipal water supplies. It is also an effective precipitant for soluble phosphate in sewage and is especially useful in wastewater having low alkalinity.Large quantities of sodium aluminate are used in papermaking where it improves sizing, filler retention,and pitch deposition.The addition of sodium aluminate to titanium dioxide paint pigment improves the nonchalking performance of outdoor paints.Sodium aluminate is widely used in the preparation of alumina-based catalysts. Aluminosilicate can be prepared by impregnating silica gel with alumina obtained from sodium aluminate and aluminum sulfate. Reaction of sodium aluminate with silica or silicates has produced porous crystalline aluminosilicates which are useful as adsorbents and catalyst support materials, ie, molecular sieves.

UsesSodium Aluminate is used in method for producing Zeolite with enhanced Silicon/Aluminum.

General DescriptionWater solution of the white crystalline powder. Corrosive to metals and tissue.

Preparation methods · 1 item

PreparationSmall amounts of sodium aluminate are prepared in the lab by fusion of equimolar quantities of sodium carbonate and aluminum acetate, Al(C2H3O2)3, at 800°C. Other methods involve reaction of sodium hydroxide with amorphous alumina or aluminum metal.Commercial quantities of sodium aluminate are made from hydrated alumina, in the form of aluminum hydroxy oxide, AlO(OH), or aluminum hydroxide, Al(OH)3, a product of the Bayer process which is used to refine bauxite, the principal aluminum ore.Commercial grades of sodium aluminate are obtained by digestion of aluminum trihydroxide in aqueous caustic at atmospheric pressure and near the boiling temperature.
