Air Pollution Student’s name Institutional Affiliation Air Pollution I chose air pollution as the topic because air is one of the most critical requirements of life, and without it, life would stop within seconds. Valero (2014) says that air pollution has become a widespread problem around the world and humans are almost losing the battle for clean air. In spite of the efforts over the years to combat air pollution, it is taking an ever increasing toll on human health, the economy, and the environment. According to Shifrin (2014), air pollution was an exclusive problem of the urban centers in the industrialized world, but now it is a global phenomenon and more than a billion people or 1/5th of all humanity lives in environments with air quality that do not meet the quality standards set by the WHO. The three key points to understanding air pollution are; 1. The types of pollutants 2. Sources of air pollution 3. Effect of air pollution The Type of Air Pollutants There are primary and secondary air pollutants. The primary air pollutants include the Sulfur oxides, Nitrogen oxides and other toxic by-products of industrial processes. Further oxidation of Sulfur dioxide (SO2) in the presence of a catalyst would result in acid rain that is potentially harmful. Nitrogen oxides like Nitrogen dioxide (NO2) are also emitted in high-temperature combustion and have similar effects. These oxides are responsible for photochemical smog. Other primary pollutants include carbon dioxide (Co2), carbon monoxide (CO), Volatile Organic Compounds (VOC), Particulate matter, toxic heavy metals, Ammonia (NH3), Chlorofluorocarbons (CFCs), and radioactive pollutants (Valero,
