. This report summarizes results of a project to character& air toxic emissions of selected hazardous air pollutants (HAPS) from the AirPol Gas Suspension Absorption SO2 control technology. This project was sponsored by AirPol Inc., the Tennessee Valley Authority (TVA), and the U.S. Department of Energy (DOE). The GSA process utilizes a semi-dry lime scrubber for SO2 and HCI removal. Most of th...

This study evaluated in vivo imaging capabilities and safety of qualitative monitoring of oxygen saturation of hemoglobin (sO2) of rabbit ciliary body tissues obtained with acoustic resolution (AR) photoacoustic tomography (PAT). AR PAT was used to collect trans-scleral images from ciliary body vasculature of seven New Zealand White rabbits. The PAT sO2 measurements were obtained under the foll...

OBJECTIVE To evaluate the dynamics of skin microvascular blood flow (BF) and tissue oxygenation parameters (OXY) measured simultaneously at the same site using a combined non-invasive BF+OXY+temperature probe. METHODS Skin BF, oxygenated (oxyHb) and deoxygenated (deoxyHb) haemoglobin and mean oxygen saturation (SO2 ) were measured in 50 healthy volunteers at rest and during perturbation of lo...

The global flux of sulfur dioxide (SO2) emitted by passive volcanic degassing is a key parameter that constrains the fluxes of other volcanic gases (including carbon dioxide, CO2) and toxic trace metals (e.g., mercury). It is also a required input for atmospheric chemistry and climate models, since it impacts the tropospheric burden of sulfate aerosol, a major climate-forcing species. Despite i...

Ground-level sulphur dioxide is one of the air pollutants of high concern as a typical indicator of urban air quality. To inform decisions regarding, for instance, the protection of public health from elevated SO2 levels in the city of Balikesir, an understanding of spatial-temporal variance of SO2 patterns is necessary. Therefore, the aim of this study is to locate sample points, characterize ...

The adsorption and separation behavior of SO2-CO2, SO2-N2 and CO2-N2 binary mixtures in bundles of aligned double-walled carbon nanotubes is investigated using the grand-canonical Monte Carlo (GCMC) method and ideal adsorbed solution theory. Simulations were performed at 303 K with nanotubes of 3 nm inner diameter and various intertube distances. The results showed that the packing with an inte...

The effect of elevated level of SO2+NO2 on some physiological and biochemical parameters of Glycine max were examined. Twelve days olds Soybean (Glycine max) seedling were exposed to two different (2% and 3%) levels of SO2+NO2 mixture. Fumigants were applied for 30 minutes per day, 3 days per week for 3 weeks duration. Aeration with enriched SO2+NO2 air resulted in higher phenolic content as co...

sarcheshmeh copper complex is the largest producer of copper in iran. with copper production, high amounts of so2 are being produced in this complex and emmited into the environment. so, in this study, the social optimum level of so2 released from this complex and the optimal tax rate will be evaluated. for this purpose, md and mac curves were estimated. the wtp for the reduction of so2 emissio...

The use of sulphur dioxide (SO2) in the treatment of foodstuffs presents some problems as it could lead to pseudo-allergies in some people. The aim of this research work was to study the addition of different preservative mixtures and their influence on the concentration of volatile compounds and sensorial quality in wine. To do so, vinifications were carried out using Garnacha must to which ly...

A systematic density functional theory (DFT) analysis has been carried out to obtain information at the molecular level on the key parameters related to efficient SO2 capture by ionic liquids (ILs). A set of 55 ILs, for which high gas solubility is expected, has been selected. SO2 solubility of ILs was firstly predicted based on the COSMO-RS (Conductor-like Screening Model for Real Solvents) me...
