Air Pollution and Climatic Changes
AIR POLLUTION AND CLIMATIC CHANGES
Introduction:
Air pollution is actually the addition of any harmful substances to the atmosphere, which causes the damaging of the environment, human health and the quality of life. Air pollution has been a serious problem throughout the history. This can have series effect on the health of human beings. Every day, the average person inhales about 20,000 liters of air. Every time when we breathe in we inhale dangerous substances. These dangerous substances can be in the form of gases or particles.
Sources of Air pollution:
• Natural source
• Artificial source
Natural sources:
Natural air pollution does not occur in abundance and also possesses little threat to health of the peoples and ecosystem. Volcanic eruptions, Forest fires, Biological decay of organic matters are some of the natural causes of air pollution.
Artificial sources:
The man made reasons for air pollution are vehicular emission, burning of waste products, thermal power plants, industries and refineries. Vehicular emissions are responsible for 70% of the country’s air pollution.
* Bharat stage 1 to 4 emission norms are emission standards that focus on regulating pollutants released by automobiles.
Most sulphur dioxide comes from power plants that use coal as their fuel. Automobiles produce about half of the nitrogen oxide.
When wood, household garbage, plastic, or leaves are burned, they produce smoke and release toxic gases. The smoke contains vapors and solid compounds suspended in the air called particulate matter. The particulate matter and toxic gases released during burning can be very irritating to people’s health.
People who are exposed to these air pollutants can experience eye and nose irritation, breathing difficulty, coughing, and headaches. People with heart disease, asthma, emphysema, or other respiratory diseases are especially sensitive to air pollutants
Major air pollutants:
• Sulphur oxide
• Nitrogen oxide
• Carbonmono oxide

    Air pollution is the initiation of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or damages the natural environment into the atmosphere. Air pollution occurs when the air contains gases, fumes, dust, or other harmful agents. According to Morgan (2003), air pollution was not a problem until the 19th century and Industrial Revolution because pollution was readily diluted in the atmosphere (Morgan, Environmental Health, 2003, p. 247). Air pollution occurs in many forms but can generally be thought of as gaseous and particulate contaminants that are present in the earth 's atmosphere (Air Pollution - Its Nature, Sources, and Effects, 2013). Natural sources of air pollution include forest fires, dust storms, and volcanic eruptions (Morgan, Environmental Health, 2003, p. 249).…

    Air pollution is caused by many things, earth is very good at cleaning the air on its own, though through the years air pollution has gotten to a very bad point where earth can no longer clean all of the pollution we produce which has now started to have very bad effects on our environment such as causing acid rain, smog and a lot of health problems. There are a variety of things that cause air pollution like for example cars, airplanes and other engine vehicles. All these engine vehicles release a great amount of pollution into the air which contains carbon monoxide, nitrous oxide and gaseous oxide which all cause smog as seen in Los Angeles which unfortunately cause a lot of respiratory health problems and holes in the ozone layer which is the layer that protects us form the harmful rays of the sun which means by these holes being created with all this air pollution we are exposing ourselves to the sun’s harmful rays which can also cause skin cancer. There is also factories, office buildings, Home and power generating stations which burn fossil fuels and cause even more air pollution. The burning of oil and coal from fossil fuels also is a big contributor of smog all the air pollution released form these factories, office buildings, homes and power generating stations destroys plants, damages buildings and creates oxidation on iron. Radioactive fallout causes air pollution form the nuclear energy dispersed, which is dust. Pesticides used to kill indoor and outdoor pests, insecticide use to kill insects and herbicides used to kill weeds also cause air pollution. Fertilizer dust used in many farms all farms I think which is supposed to help plants grow also causes air pollution. Mills and plants, include paper mills, chemical plants, iron mills, steel mills, cement plants and asphalt plants, release emissions into the air causing even more pollution.…

    One of the main causes of air pollution is manufacturing. This source of pollution spews particulate matter and chemicals into the atmosphere. The particulate matter and chemicals that come from a factory includes Sulfur oxides, Nitrogen oxides, Carbon monoxide and dioxide. And these kinds of chemicals and pollutions are very harmful to humans, animals, nature, and other living things. For example, when these kinds of pollutions are spewed up into the space, they’re going to break the Ozone that protects us from the sunlight. Moreover, they also can make us unhealthy such as; decrease our lung functions, cough, shortness of breath, and also make asthma and other lung diseases get worse. So these chemicals and pollutions are very harmful to humans and other living things.…

    Smoke from chimneys, factories, vehicles or burning of wood basically occurs due to coal burning; this releases sulphur dioxide into the air making it toxic. The effects of air pollution are evident too. Release of sulphur dioxide and hazardous gases into the air causes global warming and acid rain; which in turn have increased temperatures, erratic rains and droughts worldwide; making it tough for the animals to survive. We breathe in every polluted particle from the air; result is increase in asthma and cancer in the lungs.…
