Bioavailability of Vanadium Extracted by EDTA, HCl, HOAC, and NaNO(3) in Topsoil in the Panzhihua Urban Park, Located in Southwest China.
Summary of "Bioavailability of Vanadium Extracted by EDTA, HCl, HOAC, and NaNO(3) in Topsoil in the Panzhihua Urban Park, Located in Southwest China."
Bioavailable vanadium was evaluated on the basis of soil vanadium single-extraction with ethylenediaminetetraacetic acid (EDTA), hydrochloric acid (HCl), acetic acid (HOAc), and sodium nitrate (NaNO(3)) in Panzhihua urban park. The soil vanadium concentration extracted by HOAc was 0.01-2.07 mg kg(-1), by EDTA 0.28-7.03 mg kg(-1), by NaNO(3) 0.07-0.53 mg kg(-1), and by HCl 0.19-1.36 mg kg(-1). The bioavailable vanadium (bioavailable fraction) obtained with HOAc was 0.01-1.33%, with EDTA 0.27-4.09%, with NaNO(3) 0.13-0.72%, and with HCl 0.06-0.28%. In addition, the impact of soil properties, soil nutrients, and soil enzyme activities on bioavailability of vanadium is discussed in this study. Based on the characteristics of bioavailable vanadium in the soil, ecological and health risks should have been given more attention in the studied area.

Medical and Biotech [MESH] Definitions
Vanadium Compounds
Inorganic compounds that contain vanadium as an integral part of the molecule.
Vanadium
A metallic element with the atomic symbol V, atomic number 23, and atomic weight 50.94. It is used in the manufacture of vanadium steel. Prolonged exposure can lead to chronic intoxication caused by absorption usually via the lungs.
Indinavir
A potent and specific HIV protease inhibitor that appears to have good oral bioavailability.
Insulysin
An enzyme the catalyzes the degradation of insulin, glucagon and other polypeptides. It is inhibited by bacitracin, chelating agents EDTA and 1,10-phenanthroline, and by thiol-blocking reagents such as N-ethylmaleimide, but not phosphoramidon. (Eur J Biochem 1994;223:1-5) EC 3.4.24.56.
Talampicillin
An ester of AMPICILLIN which is readily hydrolysed on absorption to release ampicillin. It is well absorbed from the gastrointestinal tract resulting in a greater bioavailability of ampicillin than can be achieved with equivalent doses of ampicillin.
