Smog can cause health problems and is a serious environmental issue. Causes Traditionally smog came from the smoke produced by burning coal in factories

Photochemical Smog Gifted Chemistry IB Alternative Assessment 1997 March 19 Historically‚ the term smog referred to a mixture of smoke and fog‚ hence the name smog. The industrial revolution has been the central cause for the increase in pollutants in the atmosphere over the last three centuries. Before 1950‚ the majority of this pollution was created from the burning of coal for energy generation‚ space heating‚ cooking‚ and transportation. Under the right conditions‚ the smoke and sulfur dioxide

Smog pollution in Beijing Smog pollution has been around since the start of industrialization‚ and there are many cities that suffer from its consequences. Among them‚ Beijing is singled out as the hotspot these days. In the past winter‚ an unprecedented amount of smog cloaked Beijing‚ filling the city with noxious air and causing convulsive coughing among the local residents. Not only does smog cause inconvenience in transportation by reducing visibility‚ but also‚ according to a study at

are many kinds of air pollution‚ one of them is smog. Smog can come from many areas‚ particularly factories and transportation systems‚ but there are some differences between developed and developing countries. In developed countries‚ highly developed industry is the main reason that smog is serious‚ they mostly use fossil fuels. However‚ developing countries started to industrialize‚ so increasing number of factories is the most important cause of smog and they always use the coal or wood burning.

As of April 2000‚ Houston‚ Texas flunked the air quality test given by the American Lung Association of Texas. The city was carefully being watched because of the alarming reports taken from 1996-1998. Houston ’s smog and ozone levels have now surpassed Los Angeles ’s notorious air pollution problem.

another breath. Such is the life for the average Los Angeles resident. A city dominated by warm climate‚ show business‚ and extravagant lifestyles has been negatively impacted by the ever-present problem of smog. Noted as a problem for over 100 years in the city‚ the only advances in the “Smog War” ("The southland ’s war‚" 1997) have been made in the last 60 years or so‚ leaving a certain level of pollution that likely will never be solved. Since 1947 Los Angeles has dedicated itself to improving

In 1952‚ a toxic smog covered London. This fog continued to blanket the city for four days. Although this is a short period of time‚ the smog had a fatal aftermath. This still continues today and affects the people who were exposed to the toxic fumes. There were many things that contributed to the way the smog started‚ ended‚ and how it became toxic. One main reason why the smog started and lasted so long was because of the weather. There was a high-pressure air mass stalled over the Thames

Smog can form in almost any climate where industries or cities release large amounts of air pollution‚ such as smoke or gases. However‚ it is worse during periods of warmer‚ sunnier weather when the upper air is warm enough to inhibit vertical circulation. It is especially prevalent in geologic basins encircled by hills or mountains. It often stays for an extended period of time over densely populated cities or urban areas‚ such as London‚ Atlanta‚ Houston‚ Phoenix‚ Las Vegas‚ New Delhi‚ New York
