... these pollutants also come from natural sources. For example, forest fires emit particulates and Volatile organic chemicals into the atmosphere. Ultrafine dust particles, dislodged by soil erosion when water and weather loosen layers of soil, increase airborne particulate levels. Volcanoes spew out sulfur dioxide and large amounts of pulverized lava rock known as volcanic ash. A big ... already gone through a period of rapid and dirty industrialization, are ready to demand cleaner technologies. Less developed nations, hoping for rapid economic growth, are less enthusiastic about pollution...

... with an adequate margin of safety, taking into account both the available evidence and the inevitable scientific uncertainties." Secondary NOx concerns include its contributions to acid rain, deterioration of water quality, and atmospheric visibility. NOx, when reacting with sulfur dioxide forms acid rain, which deteriorates cars, buildings, trees and historical monuments. Acid rain also makes lakes acidic ... Matter Particulate matter (PM) means small particles suspended in the air. Particulates are not easily identified or classified since they are "exceptionally diverse" consisting of ...

... heat of lightning (Jacobson, 2002). Also, the environmental effect of NOX is its contribution to acid rain. This occurs when nitrous oxide is able to form compounds with the water molecules during precipitation. Agricultural fertilizers and the use of nitrogen fixing plants are also known to contribute to atmospheric NOx by promoting nitrogen fixation by micro-organisms. In addition to ... , chemicals containing hydrogen and carbon that evaporate easily are known as volatile organic compounds. Many of these compounds are known to be present in the atmosphere and contributing to air pollu...

... gallons of gasoline are burned each and every day. At first glance, this seems like an efficient energy source, but upon closer consideration, it becomes obvious that the cost "pollution--dramatically overshadows the benefits. The outdated technology of the internal combustion engine, the apparatus used to convert this "magic liquid- into energy, is the sole culprit responsible for gasoline's ... , Carbon Monoxide reduces the flow of oxygen in the bloodstream and hinders mental functions and visual perception.
