Causes of smog

Many other large cities in the United States also experience smog. Classic smog results from large amounts of coal burning in an area and is caused by a mixture of smoke and sulfur dioxide. For the past few years, cities in northern India have been covered in a thick layer of winter smog. Follow all of ScienceDaily's latest research news and top science headlines! Initially a flu epidemic was blamed for the loss of life. Once in solution the sulfur was oxidized, a process often catalyzed by the presence of dissolved metallic ions such as iron and manganese. Prevention Air pollution may be prevented only if individuals and businesses stop using toxic substances that cause air pollution in the first place.

Demographics Summer smog occurs in areas where heavy traffic involving motorized vehicles are present, along with climate conditions that include high temperatures during the summer months and calm winds. During the autumn and winter months, some million tons of crop residue are burntand winds blow from India's north and northwest towards east.

Photochemical smog reactions

Using public transportation rather than individual vehicles also reduces smog conditions in major metropolitan areas. In addition, Mexico City, Mexico, and Beijing, China, are two well-known cities that regularly experience smog conditions. Sulfur dioxide dissolved in fog droplets, perhaps aided by the presence of alkaline material such as ammonia or coal ash. Sulfur dioxide— With the chemical formula SO2 where S stands for sulfur, and O for oxygen , a toxic gas with a strong, irritating smell; in nature it is released from spewing volcanoes and it is also released by human-producing industrial processes. Smog Definition Smog is the term chosen by the Glasgow Scotland public health official Henry Antoine Des Voeux at the beginning of the twentieth century to describe the smoky fogs that characterized coal-burning cities of the time. Later medical reports found that about four thousand people had died prematurely, probably because of the air pollution. During these four days, windless cold weather combined with factory emissions to render visibility practically nil. Fossil fuels— Any type of fuel, such as coal, natural gas, peat, and petroleum, derived from the decomposed remains of prehistoric plants and animals. The smog was frequently so dense that torches were provided at door entries for people to use to find their way to waiting carriages or to their homes on foot. In modern times, smog is "photochemical air pollution" caused by the burning of fuel in factories and power plants as well as other industrial production , and using volatile substances such as gasoline and paint, which release light-blocking chemicals into the atmosphere. In , Delhi won the United States Department of Energy 's first 'Clean Cities International Partner of the Year' award for its "bold efforts to curb air pollution and support alternative fuel initiatives".

There were areas where no soft coal was allowed to be burned in homes or in businesses, only cokewhich produces no smoke. It can inflame breathing passages, decreasing the lungs' working capacity, and causing shortness of breath, pain when inhaling deeply, wheezing, and coughing.

types of smog

The " Ballad of Gresham College " the same year describes how the smoke "does our lungs and spirits choke, Our hanging spoil, and rust our iron. However, the term is most properly used to describe the two distinctive types of pollution that dominated the atmospheres of late-nineteenth-century London and other industrial cities in England, known as winter smog, and twentieth-century Los Angeles, called summer smog.

Smog Facts The word "smog" is a combination of the words "smoke" and "fog. EPA has developed an Air Quality index to help explain air pollution levels to the general public.

Manahan, Stanley E. This is a very unlikely scenario at the present.
