The Sulfur Dioxide in Environment
The sulfur dioxide was regarded as the acknowledged toxic gas, and is also one of main factors for acid rain. Due to its severe toxicity, the major pollution incidents have even happened in human beings’ history. During 1st December and 15th December 1930, the toxic gases including the sulfur dioxide caused great loss for Meuse Valley in Belgium. The toxic gases led to thousands of people in the industrial zone of Meuse Valley were catched with respiratory diseases, and “nearly 63 people were dead within a week”. ( Benery B, HoetPH, Nemmar A. 2001) Additionally, many livestocks also could not survived and died of the toxic gases. In the incident, the mixture of SO2 and SO3 were the main dioxide smog. Similarly, during 26th October and 31st October in 1948, the Nonora smog in America was another sever toxic incident. (Lynne Page Snyder, 1994) The results proved that the sulfur dioxide was still the main toxic gas. Therefore, the sulfur dioxide has been proved to be the acknowledged toxic gas.
The sulfur dioxide in environment mainly mainly comes from the direct combustion of fossil fuels including coal, petroleum, and so on. Meanwhile, the combustion of fossil fuels were the main sources of the sulfur dioxide in atmosphere. Generally speaking, the content of sulfur in cola was around 3%~5%. Unde the high temperature, most of the sulfur in fuels would be decomposed through being affected by the heat, and then the sulfur was oxidized to the sulfur dioxide, being released into the atmosphere. Based on data, billion of tones of fossil fuels were consumed in the world every year. These fossil fuels were burnt for electrical energy and heat thermal energy, but the sulfur content was oxidized to the sul...

Carbon Dioxide (CO2) is a colorless gas, which was first discovered in 1577 by Van Helmont who detected it in the products of both fermentation and charcoal burning. CO2 is used in solid, liquid, and gas forms in a variety of industrial processes. These include: beverage carbonation, dry ice, welding and chemicals manufacturing. It is produced by the combustion of all carbonaceous fuels and can be recovered in an abundance of ways. It is widely used today as a by-product of synthetic ammonia production, fermentation, and from flue gases by absorption process. CO2 is also a product of animal metabolism and is important in the life cycles of plants and animals. It is present in the atmosphere only in small quantities (.03% by vol.)

Imagine living in a smog, pollution free environment where the air was clean and skies were clear. Unfortunately, we do not have this luxury of that reality in the Central Valley. As many are aware, the Central Valley has a reputation of being one of the most polluted areas in California. With the air so polluted, it makes living in the Central Valley a little more difficult for everyone, whether it is realized or not. Although there are many reasons that cause the air to be polluted, the air in the Central Valley is polluted mainly because of the large manufacture infrastructures, semi/diesel trucks, fireplaces, and farming. Indeed, there are many reasons for air pollution, but let’s move on to the first reason.
This source provides relevant information to the topic at hand. It (the source) was used to examine the origin as well as the sources of Carbon Dioxide and obtain a clear understanding of what sort of an impact it can have on the environment. Although not all of the information in the source was used because of its indirect relevance, a great amount of background information was given in order to make the subject of Carbon Dioxide clearer and easier to understand. It does not state a for or against argument but rather serves as an excellent source of factual information.
On June of 2003 near Mosul, Iraq a fire ignited from the explosion of the state run sulfur plan, Al- Mishraq, which burned for almost a month. “Public Health, 2012”. It devastated millions of lives and caused thousands of people near the area to go homeless, because of the toxins and dangerous fires near the area. It was very hot and civilians had to move away due to the heat and the bad fire. The explosion was caused when arsonists set massive amounts of gas ablaze. “Studding Iraq Fire Pollution, 2004”. A combustion of elemental sulfur to sulfur dioxide produced the largest anthropogenic plume detected to date by the Total Ozone Mapping Spectrometer. “Infrared Observation of the Al-Mishraq Sulfur Plant Fire Using the Moderate Res, 2013”. The fire, which was probably started deliberately, broke out at the Al-Mishraq state sulfur plant near Mosul. It burned for almost a month. “BBC News, 2004”. Observing the fire from space was the only want to find out how severe it actually was, says carn, because there was no way tot monitor the pollution from the ground, and news reports tat the time were sketchy. “Iraqi Fire Pollution Rivaled Volcano, 2004”. It was not sure if the explosion was on purpose or on accident. The explosion was the largest man made release of polluting sulfur dioxide ever recorded in history , it was also the largest non-volcanic sulfur dioxide event that had been detected since 1978. “Studding Iraq Fire Pollution, 2004”.

During the winter of 1952-1953, London came face to face with the “heaviest winter smog episode known to men.” (Environmental disasters) During the weeks leading to this even London had been experiencing colder than usual weather. Because of the cold weather, households were burning more coal to keep their families warm. This caused “additional coal combustion and many people travelled only by car, which caused the occurrence of a combination of black soot, sticky particles of tar and gaseous sulphur dioxide.” (Environmental disasters) During this event the numbers of deaths per day increased to a nine times the normal number in some cities. The smog approximately killed 12,000 people. Most of the victims were children and elderly people.

Fogs formed by cooling include radiation fog, advection fog, and upslope fog, fogs formed by the addition of water vapor are steam fog and frontal fog. Driving in fog is considered to be the most dangerous weather hazard, especially if it is exceptionally dense fog or combined with other adverse weather conditions. Foggy conditions are the number one cause of large multi-car
Until 10 years ago, air pollution was thought to be just an urban or local problem until it was discovered that the pollutants could move across continents and oceans. Air pollution is the fundamental factor that causes greenhouse gases, hence climate change and global warming. Air pollutants are the waste products generated from industrial and other processes. They usually come in gases, though aerosols (particles suspended in air, emitted as or formed by transformatio...
Humans and animals breathe out Carbon Dioxide, often referred to as the greenhouse gas, as a waste product. Plants take in this CO2 and use it to make food. This is called photosynthesis. During this process oxygen is released which is then breathed in by humans and animals. This procedure is repeated over and over and a natural balance is obtained. However this natural balance is disrupted by human activity. People of the world are putting more than 5.5 billion tons of CO2 into the atmosphere every year. 75% of this is caused from the burning of fossil fuels. These fuels are burnt all the time to run factories, power plants and vehicles. The main sources of CO2 emissions are electric utilities, residential buildings, industry and transportation. The other 25% is induced by the destruction of the world's forests. The reason for this is that there are less trees and plants to take in the CO2 but there is just as many, if not more, humans and animals to breathe it out.

About 20 years ago scientists first believed that acid rain was due to entirely air pollution. They were partially right. Since the beginning of the Industrial Revolution in England, pollution had been affecting all the trees, soil and rivers in Europe and North America. The use of fossil fuels, such as coal and oil, are largely to be blamed for almost half of the emissions of sulfur dioxide in the world. However, there is another cause. The other cause is naturally occurring sulfur dioxide. Natural sources which release this gas are volcanoes, sea spray, rotting vegetation and plankton.
