the trend of sustainable use of available water resources encourages textile finishing enterprisesto implement efficient wastewater treatment technologies that enable water recycling, and not just it’sdischarging into the local wastewater treatment plants (wwtp). this paper presents the results obtainedfrom the h2o2/uv treatment of wastewater from slovene textile finishing company. laboratory s...

objective: ferula szowitsiana has been widely used for medicinal purposes around the world. the anti-oxidant effect of f.szowitsiana had been proved. the current study aims to determine the protective effects of galbanic acid, a sesquiterpene coumarin from f. szowitsiana, against hydrogen peroxide (h2o2) - induced oxidative dna damage in human lymphocytes. materials and methods: human lymphocyt...

objective: it is well-known that all living cells emit ultra-weak photon emission (upe), which is due to byproducts of chemical reactions in cell metabolisms. it has been shown that reactive oxygen species (ros) in the cells enhances the upe intensity. the magnitude of such upe is extremely weak (i.e. a few to 103 photons/ (sec.cm2)), and the detection of such ultra-weak signals is hardly possi...

[1] We report new century-scale ice core records of hydrogen peroxide (H2O2), a major atmospheric oxidant, from 23 locations across the West Antarctic Ice Sheet (WAIS) and use the spatial variability of (multi-) annual mean H2O2 concentrations in snow and firn to investigate the sensitivity of ice core H2O2 preservation to mean annual temperature and accumulation rate. In agreement with the ice...

Biological production and decay of the reactive oxygen species (ROS) hydrogen peroxide (H2O2) and superoxide (O[Formula: see text]) likely have significant effects on the cycling of trace metals and carbon in marine systems. In this study, extracellular production rates of H2O2 and O[Formula: see text] were determined for five species of marine diatoms in the presence and absence of light. Prod...
