Abstract:

Various materials are used to sterilize medical instruments. Rubber and other products deteriorate owing to ozone and UV exposure. Ozone is capable of inactivating bacteria and fungi and is known to be effective in inactivating a wide range of viruses. Silent discharge is the mainstream method of ozone generation. The silent discharge method is also concerned with the generation of nitrogen oxides (NOX) caused by nitrogen molecules in the air, and the deterioration of electrodes during use poses a problem. Furthermore, nitrogen oxides react with water in the gaseous phase to produce nitric aci

Abstract:

The utilization of ozone is commonly applied in various fields, for instance, it is used as a disinfectant for water treatment, disinfecting, sterilizing medical devices and preserving foodstuffs. Ozone is a nearly colorless gas with a characteristic odor that can be detected by humans up to 0.01 ppm. It can be produced by the dielectric barrier discharge method,which is generally used as a method of generating ozone supplied by high voltage or also called high voltage plasma generators. High voltage plasma occurs in the dielectric barrier discharge air gap, as a result of the air failed in ma

The treatment of medical wastewater by the peroxone (AOP) and electro-peroxone (E-peroxone) processes was analyzed. The E-peroxone process is based on the production of hydrogen peroxide electrochemically from an O2 and O3 gas mixture produced in sparged ozone generator effluent using graphite-polytetrafluorethylene cathodes. The electrogenerated H2O2 reacts with sparged ozone to produce hydroxyl radicals.

Abstract:

Ozone is a triatomic allotrope of oxygen that can be produced in specially designed machines: ozone generators (ozonators). It breaks down to dioxygen (O2) and active atomic oxygen (O), which is a very strong oxidant. Due to the fact that its bactericidal, virucidal and fungicidal activities are 50 times more powerful than those of chlorine, ozone could be used in a wide range of applications, including disinfection, disinfestation and deodorization. Biochemical properties of ozone make it useful in both human and animal medicine. Ozone therapy has been applied in the treatment of cardiovascul

The IL-17/granulocyte colony-stimulating factor (G-CSF) axis is required for this increased neutrophilia. We hypothesized that elevated IL-6 in Adipo−/−mice contributes to their augmented responses to ozone via effects on IL-17A expression.

Abstract:

Abstract. Road traffic emits not only carbon dioxide (CO2) and particulate matter, but also other pollutants such as nitrogen oxides (NOx), volatile organic compounds (VOCs) and carbon monoxide (CO). These chemical species influence the atmospheric chemistry and produce ozone (O3) in the troposphere. Ozone acts as a greenhouse gas and thus contributes to anthropogenic global warming. Technological trends and political decisions can help to reduce the O3 effect of road traffic emissions on climate. In order to assess the O3 response of such mitigation options on climate, we developed a chemistr

Abstract:

In connection with the development of the oil and gas industry, air pollution as a result of human activities is currently relevant. Hydrocarbons, mercaptans and hydrogen sulfide are among the polluting components of the oil industry. Air pollution with this kind of toxic waste poses a real threat to human health. It can be noted that the region is polluted with gases generated by the use of organic solvents, such as gasoline, fuel oil, acetone, and benzene. The chemistry of hydrogen sulfide in the atmosphere is of great interest from a hygienic point of view. When released into the atmospheri

In this paper, the disinfection of water is investigated using plasma spark treatment and the results are compared with conventional techniques. Inactivation of the Enterococcus faecalis and Escherichia coli bacteria is considered in the treatment process of water by the plasma spark. For this purpose, many physical and chemical parameters of water are measured and the obtained results demonstrate a reduction of 8-log in colony forming units of E. coli and E. faecalis at 15 minutes and 12 minutes, respectively. The results of this research show that no ozone is produced during the plasma spark

Oxidant exposure of the airway mucosa may play a significant role in the pathophysiology of asthma and allergic rhinitis. Mast cells play an important role in asthma, and oxidant exposure has been reported to cause direct mast cell degranulation as well as augment immunoglobulin E (IgE)-mediated responses in vivo. H2O2 is an oxidant generated by inflammatory cells and by the interaction of ozone with lipids or aqueous solutions. In this study, the RBL-2H3 mast cell line was used to investigate the ability of H2O2 to induce mast cell responses as well as to effect mast cell responses to IgE and

Observations performed in the framework of IAGOS (In-service Aircraft for a Global Observing System) combine the advantages of in situ airborne measurements in the UTLS with an almost-global-scale sampling, a ∼20-year monitoring period and a high frequency.
