The use of emissions trading (cap and trade) is gaining worldwide recognition as an extremely effective policy tool. The U.S. Sulfur Dioxide (SO2) Emissions Trading Program has achieved an unprecedented level of environmental protection in a cost-effective manner. The successful results of the program have led domestic and foreign governments to consider the application of cap and trade to addr...

Introduction: The ambience of the city of Zenica, with high concentrations of pollutants in the air, as a consequence of the technological process of production of ferrous metals, causing a high risk of illness and exacerbation of respiratory diseases among residents of Zenica, especially inrisk population groups, such as children with asthma. The goal: The main objective of this work was to de...

As high-density monitoring networks observing pollutant concentrations are costly to establish and maintain, researchers often employ various models to estimate concentrations of air pollutants. The AMS/EPA Regulatory Model (AERMOD) is a fairly recent and promising model for estimating concentrations of air pollutants, but the effectiveness of this model at different time scales remains to be v...

Analysis of the Central England Instrumental Temperatures data set (1659-present) has provided answer as to cause decreased temperatures during Little Ice Age (LIA) (and undoubtedly, also those all other Ages). The were caused by injection reflective (dimming) Sulfur Dioxide (SO2) aerosols into stratosphere from extensive occurrences VEI4-VEI7 volcanic eruptions.

Abstract. Sulfur dioxide (SO2) is a major atmospheric pollutant and precursor of sulfate aerosols, which influences air quality, cloud microphysics, climate. Therefore, better understanding the conversion SO2 to essential simulate predict sulfur compounds more accurately. This study evaluates effects in-cloud aqueous-phase chemistry on oxidation in Community Earth System Model version 2 (CESM2)...

The maternal diet is an important determinant of glutathione-related metabolism in rats. Glutathione (GSH) may play a major role in the detoxification of sulfur dioxide (SO2) within the lungs. The effects of fetal exposure to a low protein maternal diet upon later susceptibility to pulmonary injury induced by chronic SO2 exposure were evaluated in young adult rats. Pregnant rats were fed purifi...

stabilizer such as cane sugar to liquid lime-sulfur and evaporating to dryncss. Self-boiled lime-sulfur is made by utilizing the heat of hydration or slaking of quicklime, CaO, to carry on the reactions with sulfur. Ammonium polysulfide and sodium polysulfide are made by passing hydrogen Sulfide gas, H.^S, into ammonium or sodium hydroxide containing excess sulfur. It is supposed that the chemi...

Palladium-based catalyst can be employed for natural gas exhaust clean up due to its high activity for light hydrocarbon oxidation. Unfortunately, trace amounts of sulfur in the natural gas feed severely deactivate the catalyst. In this paper, SO2 adsorption over a monolithic Pd/Al2O3 oxidation catalyst is monitored in a time-resolved manner in the presence of 100 ppm SO2 under simulated aging ...

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...
