The use of biomass indoor Honai (traditional house) in Wamena have been conducted for several decades and become a traditional habit of Honai occupants. Since air temperature at night in Wamena Regency is cold the inhabitans burn the Kasuari woods to warm their body. As a result, they continuously inhale the Sulfur Dioxide (SO2) and Nitrogen Dioxide (NO2) and some contaminated air in Honai room...

The long-range transport of oxidized sulfur (sulfur dioxide (SO2) and sulfate) and oxidized nitrogen (nitrogen oxides (NOx) and nitrate) in East Asia is an area of increasing scientific interest and political concern. This paper reviews various published papers, including ground- and satellite-based observations and numerical simulations. The aim is to assess the status of the anthropogenic emi...

Signatures of sulfur isotope mass-independent fractionation (S-MIF) have been observed in stratospheric sulfate aerosols deposited in polar ice. The S-MIF signatures are thought to be associated with stratospheric photochemistry following stratospheric volcanic eruptions, but the exact mechanism responsible for the production and preservation of these signatures is debated. In order to identify...

BACKGROUND To investigate the correlation between cerebral (SO2-transcranial), retinal arterial (SaO2-retinal) and venous (SvO2-retinal) oxygen saturation as measured by near-infrared spectroscopy (NIRS) and retinal oximetry respectively. METHODS Paired retinal and cerebral oxygen saturation measurements were performed in healthy volunteers. Arterial and venous retinal oxygen saturation and d...

Ageing is associated with changes in physical characteristics and decline of many physiological functions. It has been accepted that the oxidative stress or damage induced by free radicals is related to ageing. Three age groups, 3, 12 and 24 months, were used to investigate whether age-associated changes in some parameters (vitamin C and ceruloplasmin) in the plasma of male Swiss-Albino rats an...

Air pollution is the most serious environmental issue and becoming a threat to all over the world. SO2 is considered as one of the most poisonous and irritant gas because it alters the physiology, biochemistry and behavior of the living individuals. The present study has been conducted to demonstrate the remedial effect of Emblica officinalis against SO2 induced hepatotoxicity in albino rats. T...

There is concern about the human health effects of inhalation of acid compounds found in urban air pollution. It was the purpose of this study to investigate three of these acid compounds, sulfur dioxide (SO2), sulfuric acid (H2SO4), and nitric acid (HNO3) in a group of allergic adolescent subjects. Subjects were exposed during rest and moderate exercise to 0.7 mumole/m3 (68 micrograms/m3) H2SO...
