this paper refers to an experiment of so2 absorption to the three different sorbents: calcium-oxide (cao), calcium-carbonate (caco3) and dolomite (camg(co3)2). in the reactor under the condition of oxidation atmosphere with the mass of sorbent (sample) of 100 g with fractional composition of 500-700µm, the gas temperature varied from 200°c and 400°c. the examinations indicated that the highest ...

A regional climate model has been used to study the transport and deposition of sulfur (SO2 and SO 2− 4 ) and PbCl2 emissions from Indonesian volcanoes. The sensitivity of the atmospheric loss of these trace species to meteorological conditions and their solubility was examined. Two experiments were conducted: 1) volcanic sulfur released as primarily SO2 and subject to transport, deposition, an...

The effects of SO2 and NH3 on secondary organic aerosol formation have rarely been investigated together, while the interactive effects between inorganic and organic species under highly complex pollution conditions remain uncertain. Here we studied the effects of SO2 and NH3 on secondary aerosol formation in the photooxidation system of toluene/NOx in the presence or absence of Al2O3 seed aero...

Improving the constraints on the atmospheric fate and depletion rates of acidic compounds persistently emitted by non-erupting (quiescent) volcanoes is important for quantitatively predicting the environmental impact of volcanic gas plumes. Here, we present new experimental data coupled with modelling studies to investigate the chemical processing of acidic volcanogenic species during troposphe...

The aim of this study was to investigate the association between daily changes in respiratory health and air pollution in 489 adults, aged 50-70 yrs, with and without chronic respiratory symptoms, living in urban and nonurban areas in the Netherlands. Subjects were selected from the general population with a screening questionnaire. During three consecutive winters starting in 1992/1993, peak e...

The paper estimates the shadow prices of SO2 emissions for 36 Czech industry sectors during the period 2000-2008. A convex nonparametric least squares quadratic optimization formulated by Mekaroonreung & Johnson (2012) is applied to measure technical efficiency and to jointly estimate the shadow prices of SO2 emissions. The weighted average shadow price ranges between 360€ and 1,316€ per ton of...

The full set of high-resolution observations from the Galileo Ultraviolet Spectrometer (UVS) is analyzed to look for spectral trends across the surface of Europa. We provide the first disk-resolved map of the 280 nm SO2 absorption feature and investigate its relationship with sulfur and electron flux distributions as well as with surface features and relative surface ages. Our results have impl...

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...

In this study, a circulating fluidized bed (CFB) of 125 mm diameter and 1800mm height was used to find the combustion characteristics of sewage sludge (SS) produced in Turkey. Sludge + olive cake, and sludge + lignite coal mixtures were burned separately. Various sludge-to-lignite coal and sludge-to-olive cake ratios (5/95, 10/90, 15/85, 20/80) were tried. On-line concentrations of major compon...
