EVALUATION OF HUMAN HEALTH RISKS AND EFFECTS ON THE ENVIRONMENT The overall assessment of the risks of aluminium exposure to healthy, non-occupationally exposed humans is rendered uncertain by several deficiencies in the database, namely: i) the questionable relevance to humans of animal experiments designed for hazard identification, in which massive doses were administered by parenteral routes, and the lack of data based on oral dosing at relevant exposure levels; ii) the dubious relevance to humans of the many biochemical findings from cell culture experiments and other in vitro models; iii) the uncertainty in the analytical and estimated cumulative exposure data in epidemiological studies of the relationship of aluminium in drinking-water to Alzheimer's disease (AD), and the less than robust dose-response data obtained from such studies; iv) the complete lack of epidemiological studies relating to total aluminium exposure, when it is considered that aluminium derived from drinking-water is responsible for only a small fraction of such exposure.
Main uses of aluminium compoundsa Aluminium compounds Uses alums hardening agent and setting accelerator for gypsum plaster, in tanning and dyeing, and (formerly) in styptic pencils aluminas in water treatment and as accelerator for concrete solidification (high alumina cements) alkoxides in varnishes, for textile impregnation, in cosmetics and as an intermediate in pharmaceutical production borate production of glass and ceramics carbonate antacid chlorides production of rubber, lubricants and wood preservatives, and in cosmetics as an astringent; the anhydrous product is used as a catalyst and raw material in the chemical and petrochemical industries; active ingredient in antiperspirants hydroxide stomach antacid, other pharmaceuticals isopropoxide used in the soap and paint industries; waterproofing textiles phosphate antacid silicate component of dental cement; antacid, food additives sulfate used in water purification as a flocculent, in paper production, as a mordant in dyeing, and as a starting material for the production of other aluminium compounds trioxide used as an absorbent, abrasive and refractory material sodium aluminium food additives phosphate a From: Helmbolt et al.
