Background & Aims of the Study: Sulfur dioxide is a component of greatest concern and is used as an indicator for the larger group of gaseous sulfur oxides (SOx). Sulfur dioxide can be absorbed into your body through the nose and lungs, its reaction with the moisture in the nose and nasal cavity, and entering the circulatory system directly through the airways. The aim of this study is ...

introduction sulfur dioxide has been widely studied among the human- made pollutants. air pollution is a major environmental risk to health. the less air pollution, the better the cardiovascular and respiratory health of the population will be, both long- and short-term. several studies have demonstrated relation between on short and long term effects exposure to air pollutants with human healt...

sulfur dioxide has two important sources in the atmosphere and this is why most of scientists believe in a geographic split in the globe. power plants, major emitter of so2, are located in north hemisphere such as in russia, china, canada and the usa. in south hemisphere, phytoplankton produces a massive amount of dimethyl sulfide (dms) and dimethyl disulfide (dmds). then these types of reduced...

results results showed that naderi and havashenasi stations had the highest and the lowest sulfur and nitrogen dioxide concentrations, respectively during 2012. maximum annual concentrations of sulfur and nitrogen dioxide were 173 and 58 μg/m3, respectively, which observed during winter 2012. approximately 5.6% of the respiratory mortality and copd cases happened when the sulfur and nitrogen di...

aims: tehran’s uncontrolled expansion, which promoted housing, public utilities, industries and increase of vehicles caused the problem of air pollution. necessary information about air quality in different places and different times is the first step of combating the air pollution. the purpose of this study was to investigate the annual, monthly and hourly average of 5 criteria air pollutants ...

Labeled sulfur dioxide was found to be extensively absorbed by spinach (Spinacea oleracea L.) leaves. Labeled sulfides detected in leaf blades following fumigations with sulfur dioxide in light indicated that photoreduction of sulfur dioxide had occurred. Measurable proportions of this labeled sulfur was localized within the chloroplast fraction. Suspensions of isolated chloroplasts supplied wi...

conclusions according to the results of this study, this increase could be due to higher fuel consumption, usage of gasoline in vehicles, oil industry, and steel and heavy industries in ahwaz. the risk of mortality and morbidity were detected at the current concentrations of air pollutants. results according to the findings, the concentration of sulfur dioxide in ahvaz had an annual average of ...

Photosynthetic oxygen evolution by isolated spinach (Spinacia oleracea L.) chloroplasts approached complete inhibition in the presence of a 5 mm concentration of sulfur dioxide. A similar inhibition was observed in the presence of equimolar concentrations of bisulfite ions, suggesting a parallel mode of action. In contrast, an equimolar concentration of sulfite ions was markedly less inhibitory...
