the exposure of workers to magnetic field that occur in aluminum reduction potrooms has been studied. the pattern of magnetic field intensity has been demonstrated along the shop. it has clearly been shown that the personnel working near the pots are exposed to 20-to 1000-gauss magnetic field. to set limits of exposure to magnetic fields, the literature on the biological effects of stationary m...

Inorganic aluminum ions, [Al(H2O)6]3+, [Al(OH)(H2O)5]2+, and [Al(OH)2(H2O)4]+, are toxic to a number of crops. The aim of this study was to estimate the danger of soil contamination of bioavailable aluminum and heavy metals forms because of alum sludge which was a by-product of water, and wastewater treatment technology using aluminum coagulant is introduced into the soil. Aluminum and selected...

ed above, the letter below from one of our readers was submitted on June 10, 2004 to the Journal of the National Cancer Institute but was declined for publication. This journal [J Nat Cancer Inst] recently reported increased cancer incidence among cryolite industry workers.1 These findings merit comment on the implications for workers in other industries, particularly the aluminum industry. The...

The problems of blending electrolyzer and multi-constraint optimization of electrolytic aluminum scheduling in the electrolytic aluminum production process were addressed. Based on a mathematical model analysis, a novel hybrid optimization algorithm is proposed for optimization of blending together the molten aluminum in different electrolytic cells. An affinity degree function was designed to ...

phosphorus is an important nutrient for plant and microorganisms growth, thus has an important role in creating eutrophication of surface waters. the present study has investigated poly aluminum chloride efficiency on orthophosphate removal by coagulation and chemical precipitation process in municipal wastewater in west wastewater treatment plant. this bench scale study was performed on influe...

abstract   aluminum is one of the most important heavy metals which not only can be easily absorbed by roots, but it also damages its normal function and blocks absorption of water and nutrients. according to this fact that sunflower has been widely used in industry, this study investigates the effects of aluminum toxicity on biochemical factors in two sunflower varieties including sirena (tole...

Ariadne (ARI) subfamily of RBR (Ring Between Ring fingers) proteins have been found as a group of putative E3 ubiquitin ligases containing RING (Really Interesting New Gene) finger domains in fruitfly, mouse, human and Arabidopsis. Recent studies showed several RING-type E3 ubiquitin ligases play important roles in plant response to abiotic stresses, but the function of ARI in plants is largely...

Introduction: Although aluminum oxide nanoparticles (Al2O3-NPs) are the most widely used nanomaterials, limited studies have been reported on their toxicology. Therefore, the present study aimed to investigate the potential toxicity of aluminum oxide (alumina) nanoparticles and the protective role of aqueous extract of wormwood plant on nanomaterial-induced disorders in the lung of rats. Mater...

OBJECTIVE Four cases of pituitary adenoma among employees at a primary aluminum production factory were identified over a five year period by a community physician. The objective of this investigation was to determine whether there has been a comparable high incidence in other aluminum factories, and if particular jobs, departments, or activities in the industry are associated with higher rates...
