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...

abstract      background and objective: aluminum phosphide (alp) is a solid non-organic phosphide with dark gray or dark yellow crystals. it reacts with stomach acid after ingestion and causes phosphine gas to be released. it is thought that phosphine causes toxicity from enzymatic interference and may even lead to cell death. this study aimed to investigate the effects of poisoning with rice t...

Growing nanomaterials based consumer applications have raised concerns about their potential release into the aquatic ecosystems and the consequent toxicological impacts. So environmental monitoring of the nanomaterials in aqueous systems becomes imperative. The current study reveals the potential of Ceriodaphnia dubia (C. dubia) as a bio-indicator for aluminum oxide nanoparticles in a fresh wa...

Strain UHM-5, a pSym Exo derivative of the aluminum-tolerant Rhizobium leguminosarum bv. phaseoli strain CIAT899, was equally tolerant of aluminum (Al) as the parental culture. Dialyzed culture supernatants of the wild-type cells grown in YEM broth (10 cells ml) contained 185 mug of glucose equivalents ml whereas UHM-5 culture supernatants yielded 2 mug of glucose ml. The Exo derivative and the...

Aluminum severely affects the growth of the cyanobacterium Anabaena cylindrica and induces symptoms indicating phosphorus starvation. Preor post-treating the cells with high (90 micromolar) phosphorus reduces the toxicity of aluminum compared to cells receiving a lower orthophosphate concentration. In this study aluminum (ranging from 9 to 36 micromolar) and phosphorus concentrations were chose...

Aluminum (Al) toxicity is the primary factor limiting agricultural productivity in acid soils. The cell wall mainly composed of saccharides and first barrier for aluminum to enter plant root cells, but it unknown whether how saccharide components are involved regulating Al tolerance Lespedeza that well adapted Here, we used Al-tolerant bicolor Al-sensitive cuneata examine association with throu...

Even though aluminum is the third most common element present in the earth's crust, information regarding its toxicity remains scarce. It is known that in certain cases, aluminum is neurotoxic, but its effect in other tissues is unknown. The aim of this work was to analyze the genotoxic potential of aluminum sulfate in kidney tissue of the fish Rhamdia quelen after trophic contamination for 60 ...

Aluminum toxicity is one of the most deleterious factors for plant growth in acidic soils because over 50% of the world’s potentially arable lands are acidic. In recent years, considerable research has been conducted to understand the mechanisms of Al toxicity and tolerance in plants. This paper reviews the effects of different concentration of Al on plant shoot, root physiological parameters s...
