Reading #1: Pollutants (source: ck12.org) Particulates reduce visibility. In the western United States, people can now ordinarily see only about 100 to 150 kilometers (60 to 90 miles), which is one-half to two-thirds the natural (pre-pollution) range on a clear day. In the East, people can only see about 40 to 60 kilometers (25-35 miles), about one-fifth the distance they could see without any air pollution (Figure 1). Particulates reduce the amount of sunshine that reaches the ground, which may reduce photosynthesis. By reducing sunshine, particulates can also alter air temperature as mentioned above. Imagine how much all of the sources of particulates combine to reduce temperatures. What effect might this have on global warming? Smog is a word describing conditions forming in the air when smoke combines with high moisture levels known as fog. Hence, SMOG = SMOKE + FOG. Two types of smog are common, the classical and photochemical. The former, known as the London Smog, forms in places of wet, yet rather cold climate, with limited sunshine. The latter requires higher temperatures and plenty of sunshine and is known as Los Angeles Smog. Both types of smog require the presence of hydrocarbons originating from living Figure 1. Smog in the City of New York, back in 1965 (pre-EPA). objects. More frequently, hydrocarbons are released as a result of burning fossil fuels (coal, natural gas, gasoline or diesel) or are simply pollutants from human industrial activity. Smog causes eye and lung irritation, respiratory distress, and is particularly dangerous in individuals suffering from asthma or emphysema. Photochemical smog is particularly deadly. The mixture of hydrocarbons and moisture, in addition to sulfur and nitrogen oxides in the presence of the ultraviolet radiation from the Sun, forms particularly deadly smog containing oxidizers including ozone.
