Air Pollution
Abstract: Definitions and classifications used in the study of air pollution are introduced. lsointroduced are a brief history of air pollution, its regulation, and trends of its ambient concentrations and emissions.
Keywords: Anthropogenic, biogenic, geogenic emissions biogenic,; primary and secondary pollutants; criteria, hazardous, radioactive, indoor pollutants; sulfur smog, photochemical smog; UN-ECE, US-EPA, Clean Air Act.
Air pollution spreads easily as it travels into the atmosphere. People get exposed to air pollution not just outdoors. Even in the comforts of our houses and workplaces, air pollution can also occur. This is known as indoor pollution. Our respiratory and cardiovascular systems get affected by air pollution. The health risk air pollution poses depend on the type of chemical our bodies were exposed to, and the degree of exposure. It can either be short-term or long-term. Examples of short-term effects are eye irritation, coughing, and sneezing. While long- term effects include heart disease, lung cancer, and damage to vital organs such as brain, liver, or kidneys. Air pollution can also worsen a person's medical condition.
Air pollution is one of the virtual problems nowadays. There are many reasons of it but mostly it is caused by cars, growing cities, development of economy and industrialization. Clean air consists of several gases. When some other gases or dangerous elements get into the clean air, pollution is inevitable. Ozone layer is affected too much by pollution and it will cause serious disturbances on the environment. People are the main cause of pollution because the things that we use contain dangerous chemicals and they make atmosphere dirtier. Furthermore climate changes because of pollution. Many substances involved in the things that people use, pollute the air seriously. For instance, cigarettes contain carbon monoxide. It occurs when wood or petrol are not burned. Another one is carbon dioxide and it emerges when we
