The use of nanoparticles (NPs) has increased in recent years and consequently they are being released into the environment. The final destination of most NPs is the aquatic environment due to washing up by rain waters. Fish (n = 120) were exposed to different concentrations (0, 1, 5, and 25 mg/L) of aluminum-oxide (Al2O3), copper-oxide (CuO), and titanium-dioxide (TiO2) NPs for 14 days and 14 days of depuration period (no NP in water). Following NP exposures, activities of Na,K-ATPase, Mg-ATPase, Ca-ATPase, and acetylcholinesterase (AChE) in the brain and muscle were measured.

Adsorptive cathodic stripping voltammetric determination of aluminum at ng mL −1 levels in salt samples based on the metal complexation with Calcon (1-(2-hydroxynaphthylazo)-2 naphthol-4-sulfonic acid) and the subsequent adsorptive deposition onto a hanging mercury drop electrode was studied. Central composite design was used as a design method. Several chemical and instrumental parameters (pH, ligand concentration, deposition time, deposition potential, and complexing time) were involved in the experimental design.

The results reveal that the inhibition effectiveness was dose-dependent of the oil concentration (maximum corrosion inhibition = 94.3% for an optimal concentration of 0.8 g / L). These findings suggest that this essential oil may be a new green inhibitor agent against corrosion in hydrogen chloride solution media and could be used on food systems as an effective inhibitor of foodborne pathogens as well as for pharmaceutical applications.

Aluminum (Al) toxicity is a serious factor restricting crop productivity in acid soil, and Al is the major cause of phytotoxicity. However, the role of Al toxicity in interprimer binding site (iPBS) polymorphism, genomic instability, and DNA methylation has not been fully investigated. In the current study, the effects of different Al concentrations on iPBS polymorphism, genomic instability, and DNA methylation were investigated in seedlings of three wheat cultivars: Haymana 79, Kılçıksız, and Bezostaja 1.

The removal of bromothymol blue (BTB) from aqueous solution was studied by electrocoagulation (EC) technique using aluminum electrodes. The various experimental conditions known to influence the EC process were parameterized, including the effects of temperature, concentration, current density, pH, and treatment time. The results obtained have shown that optimum removal efficiency of 99.9% was realized at a current density of 20 mA/cm2 and pH of 4.7. The adsorption process showed a pseudo-first-order kinetic model as the best fit to the EC data.

In the case of the irradiation position at the rotary rack of the Dalat Nuclear Research Reactor (DNRR), the difference of thermal neutron flux between the bottom (3.541012 n.cm-2 .s-1 ) and the top (1.931012 n.cm-2 .s-1 ) of the 15 cm aluminum container is up to 45%. Therefore, it is necessary to accurately determine above-mentioned parameters in the sample irradiation position. The present paper deals with the determination of the distribution of thermal neutron flux along the sample irradiation container by using 0.1% Au–Al wire activation technique.

Based on the number of previous studies, this study aims to investigate the effects of process parameters of an Electrochemical Machining process which are electrolyte concentration, voltage applied to the machine, feed rate of the electrode and Inter-Electrode Gap between tool and work - piece. Aluminum samples of 25 mm diameter x 25 mm height and 30mm diameter x 25mm height of the tool is made up of copper with a circular cross section with 2 mm internal hole. The design of the system is based on the Taguchi method.

Aluminum is used in a wide range of applications and is a potential environmental hazard. The known genotoxic effects of aluminum might play a role in the development of breast cancer. However, the data currently available on the subject are not sufficient to establish a causal relationship between aluminum exposure and the augmented risk of developing breast cancer.

The effect of Aluminum toxicity on seed germination and other biochemical parameters of two varieties of Barley (RD2052 and RD2552) differing in their sensitivity to aluminum toxicity were studied. In present study different concentrations of Al (Control, 2mM, 4mM and 6mM) were used to impose Aluminum toxicity under in vitro condition and amelioratingrole of Salicylic acid and Ascorbic acid by seed priming method was studied.

Phosphorous is one of the most abundant metallic element found in the earth’s crust and present in soils in both organic and inorganic forms. Though it is present in high concentration, only 0.1% of the total P is available to plant because of poor solubility and its fixation in soil with other metallic elements in the soil such as Ca, Al, Fe to form calcium phosphate, aluminum phosphate and ferrous phosphate and thus becomes unavailable to plants.

Liquid waste from Nong Son uranium ore processing is treated with concentrated acid, agglomerated, leached, run through ion exchange and then treated with H2O2 to precipitate yellowcake. The liquid radioactive waste has a pH of 1.86 and a high content of radioactive elements, such as: [U] = 143.898 ppm and [Th] = 7.967 ppm. In addition, this waste contains many polluted chemical elements with high content, such as arsenic, mercury, aluminum, iron, zinc, magnesium, manganese and nickel. The application of the triditional method as one stage...
