near surface ozone in urban areas can be potentially hazardous for the city dwellers. as a secondary pollutant it can also be an indicator for other air pollutants as nitrogen oxides, nox and phenol acetate nitrate (pan). in this paper time and spatial variations of near surface ozone and the effective meteorological parameters influencing it concentrations, have been investigated for tehran fo...

spatial-temporal modeling of air pollutants, ground-level ozone concentrations in particular, has attracted recent attention because by using spatial-temporal modeling, can analyze, interpolate or predict ozone levels at any location. in this paper we consider daily averages of troposphere ozone over tehran city. for eliminating the trend of data, a dynamic linear model is used, then some featu...

changes in proximate composition, colour and textural characteristics of ozone-processed shrimp as affected by combined effects of increasing ozone exposures and iced storage were investigated and for the first time. whilst proximate composition comprised of fat, moisture, and protein contents and colour comprised of l*, a*, b* and metric chroma (c), the texture comprised of adhesiveness, fract...

introduction: knee osteoarthrosis is one of the most debilitating diseases. prolotherapy includes intraarticular injection of various drugs to decrease inflammation. injection of intradiscal o2-o3 has reduced pain and disability of patients with low back pain due to prolapsed lumbar disk. objective: to compare the effect of intraarticular injection of ozone and steroids in improvement of clinic...

Background and Objective: Skin ulcers and their slow healing are considered as one of the important medical aspects. Nowadays, various antibiotics and materials are used to accelerate the wound healing process. One of the methods taken in the field of wound healing is using ozone. On the other hand, one of the factors that hurt the speed of wound healing is stress. Therefore, the present study ...

ozone is an important chemical constituent of the atmosphere, and stratosphere it protects the earth surface from harmful uv radiations, such that it is known as “good ozone” while, in the lower troposphere it is a highly oxidizing pollutant and known as “bad ozone”. it is also a greenhoure gas that can affect the climate. hence, the study of spatial and temporal variations of ozone is importan...

due to the wide range of applications for ozone and its increasing use for medical and industrial purposes, studying its effects has become a very important line of research. the ozone has been suspected to be a carsinogen. because of the increasing use of ozone, the human could be more and more exposed to this gas. in this study the effects of ozone inhalation on chromosomes and its clastogeni...
