SO2 Emissions
NOx Emissions
Above is a figure that shows the total for SO2 Emissions. The graph shows a sharp drop in emissions starting in 2010 with the implementation of flue gas desulfurization. SO2 (sulfur dioxide) emissions primarily result from the combustion of fuels containing sulfur, like coal. High levels of sulfur dioxide in the atmosphere can make breathing difficult for those with sensitive respiratory systems. It can also be responsible for the formation of acid rain and particulate matter, damaging the environment and creating smog.
The above figure shows the total NOx emissions in tons. The graph shows a negative slope, coinciding with the use of NOx control technologies around 2000 and 2010. NOx (Nitrogen Oxide) is a product of reactions between Nitrogen and Oxygen present in the air during combustion. At high levels, nitrogen dioxide irritates the airways, and makes breathing difficult, extended exposure to NOx can impede lung function, increase response to allergens, and risk of lung conditions. NOx emissions forms ground level O3 (ozone) that contributes to smog, acid rain, and fine particle accumulation in the air.
CO2 Emissions
Above is a figure that shows the total CO2 Emissions. CO2 (Carbon Dioxide) is a greenhouse gas that has dramatically increased in the atmosphere since the industrial revolution. Emissions mainly affect human health and the environment. Health issues may include headaches, dizziness, and trouble breathing. Increasing concentrations of CO2 are closely tied to climate change and is commonly used as a predictor of future environmental changes.
