Pollution Summary Essay
What is ambience Pollution? The air we breathe supplies the oxygen that sustains life. mankind need oxygen to survive, and plants and animals need oxygen to survive. Our air supply has turn contaminated by human activity. We mystify created machinery that has stated smog and acid rain. We have created a green house effect and have made holes in our oz unmatched layer. Each of these acts nates cause serious health problems for humans and animals, and can cause grave harm to our vegetation and ecosystems. There argon heptad main types of air pollutants.Raven (2008) describes them as particulate case, due north oxides, sec oxides, hydrocarbons, ozone, air toxics, and carbon oxides. Particulate matter can come from dust, soil, soot, and asbestos due north oxides come from gasses that be produced by chemical interactions between atmospheric nitrogen and oxygen. Sulfur oxides come from chemical interactions between reciprocal ohm and oxygen. Hydrocarbons come from chemical interactions between hydrogen and carbon. Ozone comes in two forms (1) oxygens chemical reaction with UV radiation in the stratosphere and, (2) oxygen reaction in the troposphere what creates smog. vent toxics can be radioactive substances, fluorides, and hydrochloric acid, and carbon oxides ar carbon monoxide and dioxide. Causes of Air Pollution Chemicals, human sources, and raw(a) sources contribute to air contaminant. Air befoulment can be traced all the way back to Ancient roman letters times. Every day, the average person inhales about 20,000 liters of air. Every time we breathe, we insecurity inhaling dangerous chemicals that have found their way into the air. (Caroline, David, Michael, Mindy, Neil, and Vikas, 1999, The Environment A ball-shaped Challenge.Air Pollution). Air pollution occurs in the atmosphere and can shanghai easily from one location to another, it is a global concern. Air pollution is a problem both outdoors and inside homes. Chemicals There are seve n main types of air pollutants according to a regulatory perspective. These are particulate matter, nitrogen oxides, atomic number 16 oxides, carbon oxides, hydrocarbons, ozone, and air toxics. Particulate matter is made of thousands of solid and transparent particles hanging in the atmosphere. Solid particulate matter is commonly known as dust whereas as liquid articulate matter is known as mist. Particulate matter includes the succeeding(a) pollutants soot, lead, asbestos, soil particles, sea salt, and sulfuric acid droplets. Nitrogen oxides are gases produced as a result of interaction between nitrogen and oxygen involves a supply of energy such as combustion of fuels resulting in mellowed temperatures. Sulfur oxides are gases. These gases are a result of a chemical interaction between sulfur and oxygen. When combined with water, the result is sulfuric acid. vitamin C oxides rest of carbon monoxide and carbon dioxide.Carbon monoxide has no color, smell, or hear and is seco nd as an air pollutant only to carbon dioxide. Carbon dioxide is similarly does not have color, smell, or taste and is a greenhouse gas. Hydrocarbons consist are a varied collection of organic compounds including hydrogen and carbon. puny hydrogen molecules are gaseous at room temperature. Hydrocarbons include methane (colorless and odorless gas principally included in natural gas), benzene (which is a liquid at room temperature), and paraffin (which is a solid at room temperature).Ozone is a form of oxygen that is a pollutant in one sweep of the atmosphere but essential in another area of the atmosphere. Hazardous air pollutants (HAPS) consist of hundreds of other air pollutants such as chlorine, lead, hydrochloric acid, formaldehyde, radioactive substances, and fluorides. Humans Many chemicals that cause air pollution equal naturally in our world. These chemicals are harmful in both their natural form however, become even more harmful when burned by humans for fuel, heat, or electricity.The two main causes of air pollutants in urban areas are transportation and fuel combustion from stationary sources. The stationary sources are heating and cooling for buildings and coal-burning power plants. Vehicles such as cars, trains, heavy-duty trucks, and airplanes, produce high amounts of carbon dioxide while fuel combustion produces high amounts of sulfur dioxide. Chlorofluorocarbons (CFCs) are man-made compounds that were originally developed in 1930 as a safer alternative to the refrigerants then in use such as sulfur dioxide and ammonia.
