Air pollution Essay example

You can not get rid of it. Everyone has to breathe, and when your air is not clean your health will be affected. Air pollution is a problem for all of us. You may feel healthy because you are doing only healthy and healthy things. Everyone is affected by air pollution

First of all, what is air pollution? Air pollution is air pollution caused by emission of harmful substances. There are many contaminants that can cause air pollution. Like carbon monoxide, carbon dioxide, chlorofluorocarbon, lead etc. All of these contaminants can cause various diseases such as cancer, birth defects, brain and nerve damage, long-term injuries.

The other pollutants in the car are lead; it is a very toxic metal. Lead phased out petrol, but there are other sources. It includes paint, lead battery production, water pipes and several inherited dye products. Automobile exhaust gases may produce nitrogen oxides, volatile organic compounds, which are products of burning fuels. Factories and power plants produce the same pollutants as automobiles, but they are produced in larger scale and more products like sulfur dioxide manufactured during papermaking, power plant coal or metal smelting I will. Burning other fuels such as wood and natural gas will also produce all these contaminants.

Another problem closely related to industrialization is the big city problem. Due to the dangers of cars, buses and trucks, the problem of air pollution is increasing in big cities. During a traffic jam, various pollutants are released into the air and people living near the road must suck this "dirty" air.

We use various chemical substances to destroy air. Spray containing chlorofluorocarbon destroys the ozone layer at the top of the atmosphere. Pesticides and other chemicals used to protect certain plants may protect plants, but they do not help our air at all.

The cause of air pollution, there are too many reasons for air pollution, we can not believe it is the cause

Air pollution is often referred to as primary or secondary pollutant. Major pollutants are pollutants emitted directly to the atmosphere from people or natural sources. Examples of major pollutants are exhaust gas (gas) from automobiles, smoke from smoke, dust, ash from volcanic eruption (see the left figure). Secondary pollutants are pollutants produced by chemical reactions when pollutants are mixed with other major pollutants or natural substances such as water vapor. When major pollutants react with sunlight, many secondary pollutants are produced. Ozone and smoke are secondary pollutants. Ozone is a gas that blocks the sun from harmful ultraviolet rays. But as it approaches the ground it harms people and other creatures.

When harmful substances such as particles and biomolecules are taken into the atmosphere of the earth, air pollution is caused These harmful substances are called air pollutants. These contaminants may take the form of solid waste, droplets, or gas. Substances mixed in the atmosphere may have devastating effects on living things and the environment. This directly complements the cause of air pollution. There is no doubt that garbage incineration exacerbates the current air pollution situation. According to estimates by the National Center for Atmospheric Research (NCAR), more than 40% of the world's waste is burned with such a fire, and release of gas and particulate matter has a serious effect on human health and climate change There is a possibility.

Human and natural factors pollute the air. Nature also plays its part, so emissions of air pollutants are not due only to human activity. According to a survey by the World Health Organization (WHO), about 70% of air pollutants are caused by human activities, while natural phenomena such as volcanoes and hurricanes account for about 20% of air pollutants. About 8,000 people were killed by the smog of London. This is an example of nature and human activities - use of cold weather and fossil fuels - how to combine contaminated air with fatal outcomes
