Molecular Storage of Ozone in a Clathrate Hydrate: An Attempt at Preserving Ozone at High Concentrations
This paper reports an experimental study of the formation of a mixed O(3)+ O(2)+ CO(2) hydrate and its frozen storage under atmospheric pressure, which aimed to establish a hydrate-based technology for preserving ozone (O(3)), a chemically unstable substance, for various industrial, medical and consumer uses. By improving the experimental technique that we recently devised for forming an O(3)+ ...
متن کاملEffects of ozone on the production and utilization of assimilates in Plantago major
The impact of ozone (O3) on the production and utilization of photoassimilates was examined in Plantago major population ‘Valsain’. Plants were exposed in controlled environment chambers to either charcoal/Purafil-filtered air (CFA) or CFA plus O3 (15 nmol mol −1 O3 overnight rising to a maximum of 75 nmol mol −1 between 12:00 and 16:00 h). Measurements of leaf gas exchange and non-structural c...
متن کاملTropospheric Ozone Pollution in Some Major Cities of West Africa and its Relationship with Atmospheric Circulations
This study utilizes a decade long (2005-2014) monthly data of Total Column Tropospheric Ozone (TCTO) in Dubson units to evaluate the spatial and temporal trend of LAO over some major cities of West Africa, namely Lagos, Accra, Niamey, Abuja, Bamako, Dakar, Agadez, Conakry, Kano, and Ouagadougou which are either capital cites or major commercial hubs, where the population ranges from 0.09 millio...

متن کاملAnalysis of high level ozone concentrations using nonparametric methods.
Controlling emissions of air pollutants and establishing air quality objectives to improve and protect ambient air quality are very important tasks of Governments. Ozone (O(3)), one of those pollutants of concern, is not emitted directly into the atmosphere, but is a secondary pollutant produced by reaction between nitrogen dioxide (NO(2)), hydrocarbons and sunlight. High levels of ozone can pr...
