The uncontrolled release of arachidonic acid (ARA) and its metabolism by lipoxygenase (LOX) pathway can induce and aggravate cellular oxidative stress. Selenium (Se) is an integral part of some antio...
In the African Cape buffalo, circulating serum xanthine oxidoreductase (XOR) produces trypanotoxic levels of hydrogen peroxide (H2O 2). Previous, preliminary studies suggest that mammalian serum XOR H...
Hydrogen peroxide (H2O2 ) plays key roles in aquatic systems, including metal redox cycling and degradation of organic matter into bioavailable forms. Abiotic photoproduction, via photo-oxidation of...
The interaction of mineral oxides (α-Al2O3, MgO, Fe2O3, and SiO2) with hydrogen peroxide was investigated using the Knudsen cell reactor. The initial reactive uptake coefficients for the commercially ...
Epidemiological studies have shown a correlation between exposure to ambient particulate matter (PM) and adverse health effects. One proposed mechanism of PM-mediated health effects is the generation ...
The first direct laboratory measurements of gaseous hydrogen peroxide uptake by authentic Gobi and Saharan dust aerosol particles as a function of relative humidity (RH) have been carried out in an en...
Dark H2O2 production rates were measured in samples collected in the Gulf of Alaska. We used a simple, novel method for determining absolute rates of dark production and decay of H2O2 , both of whic...

The effect of artificial acidic polysaccharides (PS) and exudates of Phaeodactylum tricornutum on the half-life of Fe(II) in seawater was investigated in laboratory experiments. Strong photochemical h...
A prussian blue (PB) electrodeposited on nano Ag-coated multiwalled carbon nanotubes (nano Ag-MWNTs) was reported. Also a PB/nano Ag-MWNTs composite modified glass carbon (GC) electrode was used to in...
Prussian blue (PB) was deposited on multi-walled carbon nanotubes (MWCNT) in an aqueous solution. Multi-layer composites of the MWCNT-PB hybride material were obtained by layer-by-layer assembly with...
We undertook two laboratory experiments to study the change of concentrations and the preferential elution of major ions and hydrogen peroxide during melting of a homogeneous snow pack. The elution ...
Atmospheric hydroperoxides (ROOH) were measured at Summit, Greenland (72.97° N, 38.77° W) in summer 2003 (SUM03) and spring 2004 (SUM04) and South Pole in December 2003 (SP03). The two dominant hydrop...
A box model has been used to study the annual cycle in hydrogen peroxide concentrations with the objective of determining whether the observed difference in summer and winter values reflects instabili...
