“…Emissions from the US power sector decreased by 24% in 2009 as compared to 2008, from 7.8 MT to 6.0 MT (9). The decrease was significantly greater than the corresponding drop either in total power production or in emissions of CO 2 . We argue here that the primary factor responsible for the reduction in SO 2 emissions in 2008 relative to 2009 involved a decrease in emissions of SO 2 per unit of electricity produced (we refer to this as the SO 2 emission intensity).…”

“…Price induced switching from coal to gas also contributed, as did the decrease in total power production. As we shall indicate in what follows, the reduction in SO 2 emissions occurred despite the fact that the sulfur content of coal consumed by the power sector was actually higher in 2009 than in 2008.…”

“…We focus in this paper on the implications of the shift in the power mix and other factors for sulfur dioxide (SO 2 ). SO 2 is an important air pollutant responsible for production of sulfate aerosols impacting not only public health, , but also acid rain and, potentially, climate . Recent studies , suggest that warming of the climate by increasing level of greenhouse gases has been significantly offset by cooling due to the direct and indirect impact of aerosols, with particular attention to the role of sulfur.…”

Emissions of sulfur dioxide (SO 2 ) from the US power sector decreased by 24% in 2009 relative to 2008. The logarithmic mean Divisia index (LMDI) approach was applied to isolate the factors responsible for this decrease. It is concluded that 15% of the decrease can be attributed to the drop in demand for electricity triggered by the economic recession, 28% to switching of fuel from coal to gas responding to the decrease in prices for the latter. The largest factor in the decrease, close to 57% resulted from an overall decline in emissions per unit of power generated from coal. This is attributed in part to selective idling of older, less efficient coal plants that generally do not incorporate technology for sulfur removal, in part to continued investments by the power sector in removal equipment in response to the requirements limiting emissions imposed by the US Environmental Protection Agency (US EPA).The paper argues further that imposition of a modest tax on emissions of carbon would have ancillary benefits in terms of emissions of SO 2 .

“…SO 2 is released as a gas when sulfur-rich fossil fuel is burned (such as coal or diesel), when metal is extracted from ores, and when gasoline is extracted from oil. [15][16][17] In some industrialized locations, a high probability of SO 2 exposure may be confined to the factory area itself and within the vicinity of several square miles or the original site of its generation. 18,19 Table 1 illustrates average SO 2 concentrations in various cities ("megacities") across the world.…”

Sulfur dioxide (SO2) is a problematic inhalable air pollutant in areas of widespread industrialization, not only in the United States but also in countries undergoing rapid industrialization, such as China, and it can be a potential trigger factor for asthma exacerbations. It is known that asthmatics are sensitive to the effects of SO2; however, the basis of this enhanced sensitivity remains incompletely understood. A PubMed search was performed over the course of 2014, encompassing the following terms: asthma, airway inflammation, sulfur dioxide, IL-10, mouse studies, and human studies. This search indicated that biomarkers of SO2 exposure, SO2 effects on airway epithelial cell function, and animal model data are useful in our understanding of the body’s response to SO2, as are SO2-associated amplification of allergic inflammation, and potential promotion of neurogenic inflammation due to chemical irritant properties. While definitive answers are still being sought, these areas comprise important foci of consideration regarding asthmatic responses to inhaled SO2. Furthermore, IL-10 deficiency associated with asthma may be another important factor associated with an inability to resolve inflammation and mitigate oxidative stress resulting from SO2 inhalation, supporting the idea that asthmatics are predisposed to SO2 sensitivity, leading to asthma exacerbations and airway dysfunction.

“…Sulfur dioxide (SO2) is a common air pollutant and has significant impacts on human health (De Santis and Onufrio, 1986). Inhaling SO2 is associated with increased respiratory symptoms and responses, and recent studies also imply that SO2 exposure is linked with many neurological disorders, such as stroke and brain cancer (Kampa and Castanas, 2008;Sang et al, 2010).…”
