Background & Aims: Poor air quality regarding harmful consequences as one of the most important environmental problems have challenged many metropolises. Since exposure to these pollutants can affect human health, this study aimed to investigate the health effects of SO2 and PM10 attributable to the air pollution on the health of the Urmia citizens in 2013 using software AirQ. Materials...
MOJ Food process Technol 2017, 4(4): 00101 wheat as basic food regarding both its organic and inorganic macroand micro components [2]. This consideration is the result of several factors among which the increase of analytical possibilities has to be emphasized in addition to factors related to production technology that often change (cultivars, hybrids, crop protection, fertilization, frequency...
Since 2004, the satellite-borne Ozone Mapping Instrument (OMI) has observed sulphur dioxide (SO2) plumes during both quiescence and effusive eruptive activity at Soufrière Hills Volcano, Montserrat. On average, OMI detected a SO2 plume 4-6 times more frequently during effusive periods than during quiescence in the 2008-2010 period. The increased ability of OMI to detect SO2 during eruptive peri...
Greenhouse gas emission limits are a major source of technical and policy uncertainty for electric power industry professionals. This paper tries to reduce some of this uncertainty by investigating the main forces that were responsible for the productivity gains made by the electric power sector with respect to SO2 emissions under the US SO2 cap and trade program. The SO2 cap and trade experien...
−Poly-Ethylene Glycol (PEG) 300+H2O solutions (PEGWs) has been used as a promising medium for the absorption of SO2. We investigated the UV, FTIR, 1H-NMR, and fluorescence spectra in the absorption processes of SO2 in PEGWs to present an important absorption mechanism. Based on the spectral results, the possibility of intermolecular hydrogen bond formation by hydroxyl oxygen atom in the PEG mol...
Sulfur dioxide (SO2) can enhance the formation of secondary aerosols from biogenic volatile organic compounds (VOCs), but its influence on secondary aerosol formation from anthropogenic VOCs, particularly complex mixtures like vehicle exhaust, remains uncertain. Gasoline vehicle exhaust (GVE) and SO2, a typical pollutant from coal burning, are directly co-introduced into a smog chamber, in this...
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...
This paper aims to reveal the nexus for sulfur dioxide (SO2) emission and income, as well as the effects of technical progress on SO2 emission in China based on environment Kuznets curve (EKC) hypothesis. The spatial panel technique is used in case the coefficient estimates are biased due to the negligence of spatial dependence. With the provincial panel data of China from 2004 to 2014, this is...
The heterogeneous oxidation of SO2 by NO2 on mineral dust was studied using Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS) and a Knudsen cell. This made it possible to characterise, kinetically, both the formation of sulfate and nitrate as surface products and the gas phase loss of the reactive species. The gas phase loss rate was determined to be first order in both SO2 a...
The objective of this study was to generate data that allow for estimation of the validity of oxygen saturation (SO2) values in superficial cortical capillaries as calculated by a microreflectometric system (EMPHO II). Capillary SO2 and tissue oxygen pressure (PtO2) were measured simultaneously in the cortex of n = 13 Wistar rats under normocapnic (PaCO2 = 36 mmHg) arterial normoxia (PaO2 = 92 ...
