Sulphur Dioxide in the EnvironmentSulphur dioxide was considered the recognized toxic gas and is also one of the major contributors to acid rain. Due to its serious toxicity, major pollution incidents have even occurred in human history. On December 1 and 15, 1930, toxic gases, including sulfur dioxide, caused great losses in the Meuse valley in Belgium. The toxic gases caused thousands of people in the Meuse Valley industrial zone to contract respiratory illnesses and “nearly 63 people died in a week.” (Benery B, HoetPH, Nemmar A. 2001) Additionally, many livestock animals could not survive and died due to the toxic gases. During the incident, the mixture of SO2 and SO3 made up the main dioxide smog. Similarly, on October 26 and 31, 1948, the Nonora Smog in America was another serious toxic incident. (Lynne Page Snyder, 1994) The results proved that sulfur dioxide remained the main toxic gas. Therefore, it turned out that sulfur dioxide is the recognized toxic gas. Sulfur dioxide in the environment mainly comes from the direct combustion of fossil fuels, including coal, oil, etc. During this time, the burning of fossil fuels was the main source of sulfur dioxide in the atmosphere. Generally speaking, the sulfur content of cola was around 3-5%. Under the high temperature, most of the sulfur in fuels would be decomposed by heat, and then the sulfur would be oxidized to sulfur dioxide and released into the atmosphere. According to data, billions of tons of fossil fuels are consumed worldwide every year. These fossil fuels were burned to produce electrical energy and thermal energy, but the sulfur content was oxidized to the middle of paper......view: pp.117-1392.2. Némery B, HoetPH. Online Nemmar A.
