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)
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)

Not listed by IARC. IARC classified aluminum production as carcinogenic to humans (Group 1), but did not implicate aluminum itself as a human carcinogen. (L135) A link between use of aluminum-containing antiperspirants and increased risk of breast cancer has been proposed (A235), but studies have not been able to establish a clear link (A15468).
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)
Men were fed biscuits containing alum phosphate baking powder (about 8%) in addition to normal dietary items, and blood and urine samples collected two, four, six and eight hours after the meal. Aluminium was frequently found in blood of control men (trace - 0.1 mg/100 mL), and ingestion of the aluminium rich diet caused occasional slight increase of levels of aluminium in the blood. Urine of man before and after ingestion of the aluminium rich diets only contain small amounts of aluminium (<0.5 mg excreted in 26 hours).

Rare-earth (Ce(3+)or Eu3+) or alkali-earth metal (Mn2+) doped Na3Al2(PO4)(3) phosphor powder were prepared by a combustion method. Regardless of the dopants, the Na3Al2(PO4)(3) was shown to crystallize as hexagonal (rhombohedral) NASICON phase with spheroidal micron sized particles based upon X-ray diffraction (XRD) and scanning electron microscopy (SEM) data. As confirmed by thermogravimetric (TGA) and differential thermal analysis (DTA) data, the powders were stable at high temperatures up to 900 degrees C. A broad UV emission (with maximum at 328 nm) associated with the 5d -> 4f transition of Ce3+ was observed from Na3Al2(PO4)(3):Ce3+ while Mn2+ and Eu3+ doping showed stable green and red photoluminescence emission at 515 and 615 nm, respectively. For different molar concentrations of rareearth/alkali-earth metal dopants, the PL intensity was shown to increase to a certain concentration before quenching occurred at higher concentrations. The structure and optical properties of these phosphors were evaluated. (C) 2009 Elsevier B.V. All rights reserved.

The first hydrothermal synthesis of an Al-rich alluaudite-type compound, namely disodium dimanganese aluminium tris(phosphate), which has been obtained at 1073 K and 0.1 GPa starting from the composition Na2Mn2Al(PO4)(3), is reported. The crystal structure, which has been refined in the monoclinic C2/c space group, is identical to that of natural alluaudite. The structure consists of kinked chains of edge-sharing M1 and M2 octahedra, which contain Mn2+ and Al3+ ions. The chains are stacked parallel to 101} and are connected in the b direction by the P1 and P2 tetrahedra. These interconnected chains produce channels parallel to c, which contain the large A1 and AT sites occupied by Na+ and Mn2+ ions.
