Sources of sulfur dioxide pollution In 1963, more than 23 million tons of sulfur dioxide were discharged into the atmosphere of the United States. The fossil-fueled power plant is the chief contributor to sulfur dioxide emissions and accounts for over 40% of the total emission.
Carbon dioxide exists in the Earth's atmosphere as a trace gas at a concentration of about 0.04 percent (400 ppm) by volume.Natural sources include volcanoes, hot springs and geysers and it is freed from carbonate rocks by dissolution in water and acids.s the concentration of carbon dioxide increases in the atmosphere, the increased uptake of carbon dioxide into the oceans is causing a measurable decrease in the pH of the oceans, which is referred to as ocean acidification.
