Phytotoxicity of aluminium is one of the most serious problems in limiting plant growth in acidic soils. A number of plant species exhibit inheritable aluminium tolerance by the secretion of organic acids which is highly specific to aluminium stress and localized to the root apices. Organic acids have been considered to play an important role in the detoxification of aluminium, both externally ...

Serum aluminium concentrations and biopsy specimens of bone were examined in 56 patients with end stage chronic renal failure receiving maintenance haemodialysis. Deposits of aluminium in bone specimens were often associated with low bone formation with or without osteomalacia. Serum aluminium concentrations of greater than 3.7 mumol/l (10 micrograms/100 ml) indicated a high probability of depo...

BACKGROUND Beryllium exposure occurs in aluminium smelters from natural contamination of bauxite, the principal source of aluminium. AIMS To characterize beryllium exposure in aluminium smelters and determine the prevalence rate of beryllium sensitization (BeS) among aluminium smelter workers. METHODS A population of 3185 workers from nine aluminium smelters owned by four different aluminiu...

In this study, two new Ni/La-Al2O3 catalysts were prepared by a sol-gel method, with different aluminium precursors (aluminium triisopropoxide and aluminium nitrate). The catalysts were characterized by scanning electron microscope (SEM), X-ray fluorescence (XRF), X-ray diffraction (XRD), BET specific surface area, and particle size analysis (PSA) techniques. The BET results showed that the par...

Human activities have circumvented the efficient geochemical cycling of aluminium within the lithosphere and therewith opened a door, which was previously only ajar, onto the biotic cycle to instigate and promote the accumulation of aluminium in biota and especially humans. Neither these relatively recent activities nor the entry of aluminium into the living cycle are showing any signs of abati...

Autism spectrum disorder is a neurodevelopmental disorder of unknown aetiology. It is suggested to involve both genetic susceptibility and environmental factors including in the latter environmental toxins. Human exposure to the environmental toxin aluminium has been linked, if tentatively, to autism spectrum disorder. Herein we have used transversely heated graphite furnace atomic absorption s...

For pure metals aluminum and magnesium for chemical compounds Al3Mg, Al2Mg, AlMg AlMg3 with crystallographic orientations (100), (110) (111) the work function is calculated from first principles in framework of density functional theory. It shown that dependence on concentration aluminium nonlinear. The reasons differences depending orientation are analysed.

There are unexplained links between human exposure to aluminium and the incidence, progression and aetiology of Alzheimer's disease. The null hypothesis which underlies any link is that there would be no Alzheimer's disease in the effective absence of a body burden of aluminium. To test this the latter would have to be reduced to and retained at a level that was commensurate with an Alzheimer's...

A 28-year-old woman presented with an axillary eczema that occurred after using deodorants. Patch testing revealed contact allergy to aluminium chloride. With avoidance of aluminium-containing deodorants, the eczema cleared completely. Aluminium and its salts are widely used but contact allergy to them is uncommon. It is occasionally recognised incidentally as a reaction to aluminium Finn Chamb...

Aluminium is one of the trace elements with a moderate toxic effect on living organisms. This study is to assess the influence of aluminium chloride and aluminium hydroxide intake on biochemical parameters in experimental animals for 21 days. Administration of aluminium chloride and aluminium hydroxide at a dose of 300mg/kg of body weight significantly elevates blood serum urea and creatinine c...
