Appraisal of ozone as biologically active molecule and experimental tool in biomedical sciences
(Springer, 2011)Ozone (O3) (CAS 10028-15-6) is a major air industrial pollutant and is well known for its very strong oxidative actions which affords the molecule its useful antimicrobial and deodorizing properties, but also its potential ... -
Cr(VI) formation during ozonation of Cr-containing materials in aqueous suspension: implications for water treatment
(WRC, 2012)Ozonation, or advanced oxidation processes (utilising ozone decomposition products as oxidants) are widely used in industrial wastewater and drinking water treatment plants. In these applications the use of ozone is based ... -
The effect of ozone and drought on the photosynthetic performance of canola
(Elsevier, 2018)Canola plants were fumigated in open-top chambers with ozone (O3) (120 ppb) under well-watered (WW) and water-stressed (WS) conditions for 4 weeks. Non-fumigated plants were also studied to facilitate comparison between ... -
Effect of ozone on photosynthesis and seed yield of sensitive (S156) and resistant (R123) Phaseolus VulgarisL. genotypes in open-top chambers
(Springer, 2013)Rising tropospheric ozone (O3) concentrations have been identified as a significant threat to crop production. In the present study two snap bean (Phaseolus vulgaris L.) genotypes with known difference in sensitivity to ... -
Investigating atmospheric photochemistry in the Johannesburg-Pretoria megacity using a box model
(ASSAf, 2016)Urban air pollution has become a major concern over the past decades. One of the largest conurbations in Sub-Saharan Africa is developed around the cities of Johannesburg and Pretoria (Jhb-Pta megacity). In this study, ... -
Kontrasterende invloed van chroniese osoonblootstelling op fotosintetiese elektronoordrag en CO2-assimilering in gevoelige (S156) en bestande (R123) Phaseolus vulgaris L. genotipes
(Suid-Afrikaans Akademie vir Wetenskap en Kuns, 2018)Troposferiese osoon (O3) word beskou as een van die belangrikste lugbesoedelstowwe aangesien dit wêreldwyd meer skade aan landbougewasse aanrig as al die ander besoedelstowwe saam. Weens die oksiderende aard daarvan ... -
Observations of ozone formation in southern African savanna and grassland fire plumes
(Elsevier, 2020)Open biomass burning is one of the largest sources of aerosols and reactive trace gases into the atmosphere, having a significant effect on earth's radiative budget and air quality. Biomass burning degrades air quality by ... -
Ozone concentration dependant autohaemotherapy effects on baboon antioxidant capacity and DNA integrity and repair capacity of lymphocytes
(Academic Journals, 2009)Although ozone is widely used as an alternative medicine, its safety and efficiency are met with scepticism. To shed some light on this, we assessed the effect of ozone-autohaemotherapy, using an O2/O3 gas mixture ... -
Ozone exposure of Flinders Sensitive Line rats is a rodent translational model of neurobiological oxidative stress with relevance for depression and antidepressant response
(Springer, 2015)Rationale Major depression has been associated with higher levels of air pollution that in turn leads to neurodegeneration via increased oxidative stress. There is a need for suitable translational animal models to study ... -
Ozone modulates the effects of imipramine on immobility in the forced swim test, and nonspecific parameters of hippocampal oxidative stress in the rat
(Springer, 2010)Depression has been associated with oxidative stress. There is increased awareness of the role of environmental toxins in the development of mood disorders. Ozone, a pro-oxidant and environmental pollutant, has been noted ...
