Smog is a form of air pollution. It is made up of a combination of smoke and fog. In the old days smog was mainly caused due to the burning of coal. The mixture of smoke and sulfur dioxide is what resulted in the formation of smog.However, the modern age smog does not originate from coal. Its main source is vehicular and industrials exhaust. The emissions are acted on by sunlight and a secondary pollutant is formed. The formed secondary pollutant then combines with the primary pollutant to form photochemical smog.
Photochemical smog
This type of smog forms when sunlight hits several types of pollutants that are in the air. The resulting combination of chemicals is inimical and is very dangerous. Photochemical smog is formed when there is a chemical reaction between...
Air Pollution: A Testament to Human History Air pollution is woven throughout the fabric of our modern life. A by-product of the manner in which we build our cities, air pollution is waste remaining from the ways we produce our goods, transport ourselves and our goods, and generate the energy to heat and light the places we live, play, and work.." (Davis, 1) The most important natural resource on which humans depend
Air Pollution The air that surrounds us is a mixture of 78% nitrogen; 21% oxygen; less than 1% of carbon dioxide, argon, and other gases; and varying amounts of water vapor. Any other particles, gases or unoriginal constituents hanging in the air which are not part of its original composition are called 'Pollutants' and this kind of air is called Polluted Air. Even inhaling small amounts of such air pollutants can
Pollution Since the Industrial Revolution, and especially since the proliferation of automobiles worldwide, air pollution has been a serious problem. Any industrial activity that involves the use of energy can cause pollution. This is because creating energy requires the consumption, or burning, of one source to create the desired product such as heat, light, or motion. The use of synthetic chemicals in modern industry has led to the emission of potentially
Health Consequences of Air Pollution for Military and Emergency Workers Database Validity and Originality This paper proposes a study of some of the most significant long-term and short-term effects of air-pollution on two different sets of workers. The first of these is those were affected by localized and intense air pollution that was produced as a direct result of the Gulf War, pollution that was caused for the most part by the
Urban Environmental Air Pollution Urban Environmental Issue: Air Pollution and How to Combat It Because of the significant level of urbanization in many parts of the country, the natural landscape has been changed. This has contributed to pollution of the ecosystem, much of which is magnified within the urban environment by the inability for the pollutants to readily and easily escape the population-dense areas in the same way they could in more
Urban air pollution is one of the biggest environmental concerns for my community. And not just my community; air quality has seriously deteriorated in many cities around the globe over the last 60 or so years. The increasingly poor urban air quality has been largely caused by industrialization. Vehicles exhaust has also contributed to the poor air quality. In most urban areas, air pollution is a mixture of gas-phase and
