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 burn coal or wood. When these gases contact with atmosphere, ozone layer is destroyed. The other one is lead and simply paint or batteries that we use in daily life contain lead but we should be careful since it may cause serious problems if it gets into our bodies. Generally these gases come from factories but also there are dangerous materials in our houses. In order to keep ourselves from the possible effects of pollution we have to take precautions towards air pollution. We can control ourselves and we should act carefully. So, for example, we should use public transportation, avoid spray cans. Besides, people mostly are careful regarding trees as they are sources of oxygen. Due to its importance we should keep them clean. Environment and also air are so significant for all living beings. So people should take into account this issue and they should do whatever they can to keep our environment clean. Air pollution is a horrible thing because people are polluting the environment, we can stop this by shutting down most of the coal fired power plants and lowering how much gases and other harmful things we put into the environment. Polluting the environment is hurting not only us but also the plants and animals. The reason why polluting the environment is bad is because it is putting holes in the ozone layer and is causes people to have major health problems like with their breathing. There are many different ways people can pollute the air. Smog is one of them also, greenhouse gases and carbon dioxide are all causes of air pollution. Air pollution is a mixture of natural and man-made substances in the air we breathe. The health effects of air pollution have been reported in research studies over the past 30 years. These effects include respiratory diseases such as asthma, cardiovascular diseases, changes in lung function, and death. There is evidence that exposure to air pollution has long-term effects on lung development in children. Air pollution as you know is...
