There is evidence that ozone is a radiomimetic gas. Ozone affects pollen germination in some spedes and thus may directly affect yield. 

Off-gas ozone destruction Is it also necessary to have an ozone destructor in the system when using an ELOG Yes, ozone can desorb from the water being ozonated due to over-saturation and appear in the reactor off-gas. B 2.5... 

The BCNO elements also play an important part in how the Earth itself looks today. For instance, the oxygen gas ozone is part of a layer in the atmosphere that protects the planet from the Sun s damaging radiation. Plants constantly change carbon dioxide gas into the oxygen and food that keeps animals alive. Gasoline, oil,... 

Special tests were made to determine the self-igniting characteristics of the fuel gas-ozone mixtures. 

Ozone is produced as a result of chemical reactions of hydrocarbons and nitrogen oxides in the air in the presence of sunlight. It is a pungent-smelling, faintly bluish gas. Ozone can irritate the respiratory system and impair lung function. Other oxidants that accompany ozone are strong eye irritants. 

Gas (ozone, sulphur dioxide or nitrogen dioxide) controls to simulate the effects of adding atmospheric contaminants. 

Inhalation of irritants, such as ozone, can cause systemic effects. Inflammation causes a rise in heart rate and core temperature, whereas in rats, inhalation of the irritant gas, ozone (0.05 ppm), caused near maximal decreases in heart rate and core temperature within 10 min (20). It can be argued that the drop in heart rate and blood pressure (21,22), as well as the increase in breathing frequency (23), is due to parasympathetic responses resulting from the irritant-in-... 

To estimate the effect of automobile traffic and motor fuels on ozone formation, it is necessary to know the composition of exhaust gas in detail. Figure 5.26 gives an example of a gas phase chromatographic analysis of a conventional unleaded motor fuel. 

Example of an analysis of exhaust gas by gas phase chromatography and j relative reactivity of effluents with respect to tropospheric ozone formation. I... 

The ozone fonnation in the atmosphere is induced by radiation and a result of tliree-body collisions of the oxygen atoms with O2 molecules. This process requires a higher gas density and is, therefore, not efficient in the ionosphere. 

At room temperature ozone is a slightly blue diamagnetie gas which condenses to a deep blue liquid. It has a characteristic smell, and is toxic. Ozone is a very endothermic compound ... 

The molecular formula of ozone was determined by comparing its rate of diffusion with that of a known gas. The geometric structure... 

Reference methods for criteria (19) and hazardous (20) poUutants estabHshed by the US EPA include sulfur dioxide [7446-09-5] by the West-Gaeke method carbon monoxide [630-08-0] by nondispersive infrared analysis ozone [10028-15-6] and nitrogen dioxide [10102-44-0] by chemiluminescence (qv) and hydrocarbons by gas chromatography coupled with flame-ionization detection. Gas chromatography coupled with a suitable detector can also be used to measure ambient concentrations of vinyl chloride monomer [75-01-4], halogenated hydrocarbons and aromatics, and polyacrylonitrile [25014-41-9] (21-22) (see Chromatography Trace and residue analysis). 

Phosphoms oxyfluoride is a colorless gas which is susceptible to hydrolysis. It can be formed by the reaction of PF with water, and it can undergo further hydrolysis to form a mixture of fluorophosphoric acids. It reacts with HF to form PF. It can be prepared by fluorination of phosphoms oxytrichloride using HF, AsF, or SbF. It can also be prepared by the reaction of calcium phosphate and ammonium fluoride (40), by the oxidization of PF with NO2CI (41) and NOCl (42) in the presence of ozone (43) by the thermal decomposition of strontium fluorophosphate hydrate (44) by thermal decomposition of CaPO F 2H20 (45) and reaction of SiF and P2O5 (46).
