Tissue distribution of tungsten in mice following oral exposure to sodium tungstate.
Heavy metal tungsten alloys have replaced lead and depleted uranium in many munitions applications, due to public perception of these elements as environmentally unsafe. Tungsten materials left in the environment may become bioaccessible as tungstate, which might lead to population exposure through water and soil contamination. Although tungsten had been considered a relatively inert and toxico...
متن کاملRealization of Synergism in Sodium Tungstate-Zn
The aim of this present work is to study, the corrosion behavior of carbon steel in well water in the presence of sodium tungstate (ST)-Zn 2+ -N-(phosphenomethyl) iminodiaceticacid (NPMIDA) solutions. Electrochemical studies and FTIR spectral studies and weight loss study have been employed. It was found that the inhibition efficiency (IE) of ST (50 ppm)-Zn 2+ (10 ppm) was improved from 8% to 8...
متن کاملCrystal structures of deuterated sodium molybdate dihydrate and sodium tungstate dihydrate from time-of-flight neutron powder diffraction
Time-of-flight neutron powder diffraction data have been measured from ∼90 mol% deuterated isotopologues of Na2MoO4·2H2O and Na2WO4·2H2O at 295 K to a resolution of sin (θ)/λ = 0.77 Å(-1). The use of neutrons has allowed refinement of structural parameters with a precision that varies by a factor of two from the heaviest to the lightest atoms; this contrasts with the X-ray based refinements whe...
متن کاملBiospeciation of tungsten in the serum of diabetic and healthy rats treated with the antidiabetic agent sodium tungstate.
It is known that oral administration of sodium tungstate preserves the pancreatic beta cell function in diabetic rats. Healthy and streptozotocin-induced diabetic rats were treated with sodium tungstate for one, three or six weeks, after which the species of W in serum, were analysed. An increase in serum W with treatment time was observed. After six weeks, the serum W concentration in diabetic...
متن کاملInteraction of rat liver glucocorticoid receptor with sodium tungstate.
Effects of sodium tungstate on various properties of rat liver glucocorticoid receptor were examined at pH7 and pH 8. At pH 7, [3H]triamcinolone acetonide binding in rat liver cytosol preparations was completely blocked in the presence of 10--20 mM-sodium tungstate at 4 degrees C, whereas at 37 degrees C a 30 min incubation of cytosol receptor preparation with 1 mM-sodium tungstate reduced the ...
