The rate coefficient, k, of the reaction is, however, the same as for R34 of WAE, i.e., k = 3.6 10 12 cm s . The above correction in R34 impacts the SO2 abundance and lifetime somewhat, as discussed below. [2] Once in the atmosphere, SO2 is photodissociated to produce SO, which is further photodissociated to form sulfur atoms. The reaction of SO with O2 or OH recycles sulfur atoms back to SO2 (...

OBJECTIVES To screen adult subjects with asthma for sensitivity to inhaled sulphur dioxide (SO2) and identify subject characteristics associated with that sensitivity. Medication use, symptoms, and plasma antioxidant nutrients between SO2 responders and non-responders were compared. METHODS Adult subjects (ages 18-39 years) with asthma were exposed to 0.5 ppm SO2 for 10 minutes during moderat...

For the first time, sulfur dioxide concentration was monitored between 2005 and 2016 over Iran which is among the countries with a high SO2 emission rate in the world. To that end, SO2 column concentration at Planetary Boundary Layer (PBL) from Ozone Monitoring Instrument (OMI) was analyzed. OMI is a sensor onboard the Aura satellite which can measure daily SO2 concentration on the global scale...

The conversion of SO2 into arylsulfones under metal-free conditions was achieved for the first time by reacting SO2 with (hetero)arylsilanes and alkylhalides in the presence of a fluoride source. The mechanism of this transformation was elucidated based on DFT calculations, which highlight the influence of SO2 in promoting C-Si bond cleavage.

We discuss collection 2 SO2 data from the DutchFinnish Ozone Monitoring Instrument (OMI) on board NASA EOS/Aura spacecraft and show examples of detected volcanic and anthropogenic SO2 emissions. Quantification of anthropogenic SO2 emissions requires collection 3 reprocessing available in the fall 2007.

The present studies deals with the adsorption of SO2 by manganese oxide i.e., Pyrulusite ore. Pyrulusite is used as an adsorbent for the present studies. It is found that the percentage removal of SO2 increases with the increase in contact time, follows first order kinetics and a unimolecular layer is formed during the process. The percentage removal of SO2 increases with increase in dosages an...

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...

The removal of SO2 in the presence of alkene-ozone systems has been studied for ethene, cis-but-2-ene, trans-but-2-ene and 2,3-dimethyl-but-2-ene, as a function of humidity, under atmospheric boundary layer conditions. The SO2 removal displays a clear dependence on relative humidity for all four alkene-ozone systems confirming a significant reaction for stabilised Criegee intermediates (SCI) wi...

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 objective of this work is to develop a sustainable process for simultaneous removal of waste gases such as NO, NO2, and SO2 by an electrochemically generated Ag(I)/Ag(II) redox mediator system. High removal efficiency was achieved for NO and SO2 by the wet scrubbing method at room temperature and atmospheric pressure. This removal is achieved through oxidation and absorption by contacting t...
