Can Particulate Matter and Nano Metal Oxide Particles Affect the Redox Cycling of Nitrosylcobalamin in Weakly Acidic Aqueous Solution?

Abstract Since air pollution is one of the most serious environmental problems, study effects particulate matter (PM) on physiological processes remains to be an important challenge for scientific communities. The presented studies form part project ‘Air Pollution versus Autoimmunity: Role multiphase aqueous Inorganic Chemistry’. In these we examined effect Standard Reference Material 1648a, supplied by US National Institute Standards and Technology (NIST), its inorganic constituents formation nitrosylcobalamin (CblNO) in reaction between nitrocobalamin (CblNO 2 ) ascorbic acid a weakly acidic medium. We monitored presence urban NIST PM (SRM 1648a), plasma treated (LAP) number metal oxide nanoparticles, including redox active oxides. obtained results clearly demonstrated that different nanoparticles affected rate CblNO but did not affect nature final product. Special attention was given systematic role as selected acid.
