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...

Aqueous phase reactions are important, sometimes dominant (e.g., for SO2), pathways for the oxidation of air pollutants at the local and/or global scale. In many current chemical transport models (CTMs), the transport and aqueous reactions of chemical species are treated as split processes, and the subgrid-scale heterogeneity between cloudy and environmental air is not considered. Here using la...

China continues its strategy of total emissions control (TEC) or total load control for SO2 in the Tenth Five Years (2001~2005). This paper will analyze the status of SO2 TEC in China during the Ninth Five-Years (1996~2000). Based on the results of the analysis and the theory of divisional air resources, this paper will study the target of total SO2 emissions nationwide and its allocation for d...

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 simultaneous removal of SO2/NO2 by limestone slurry was studied in a gas-liquid bubbling reactor. Experiments were carried out to find the effect of various operating parameters such as inlet concentration of SO2 and NO2, reaction temperature, O2 content in the flue gas and additive on the SO2 and NO2 removal efficiencies. SO2 removal efficiency decreased with inlet NO2 concentration, react...

BACKGROUND In asthmatic subjects bronchoconstriction is induced by inhalation of the common food preservatives sulphur dioxide (SO2) and metabisulphite (MBS). SO2 and MBS challenges share many similarities, but it is not known whether they are equivalent. In this study of subjects with mild clinical asthma equivalence was assessed by comparing SO2 and MBS reactivity by estimating the total dose...
