The causes of air pollution is including the release of smoke from car exhaust, smoke from the refinery industry, coal consumption is not controlled, and combustion in landfills. Apart from the above causes of natural phenomena also contribute to contamination, such as forest fires due to heat from the sun and also the occurrence of volcanic eruptions that can produce particles, smoke, dust with a lot of levels that affect vision around where the incident occurred. The effects of air pollution on humans are as detrimental to the human respiratory system. Human difficult to breathe in an air polluted as the air was poisoned by contaminants and gases that are not needed. Gases such as carbon monoxide poisons in the blood oxygen transport system will slow human response and the consequent effect causes drowsiness, asthma and impaired lung function.
The first type of pollution is air pollution. According to United States Environmental Protection Agency (as cited in Vallero, 2008, p. 3), air pollution is the presence of contaminants or pollutant substances in the air that interfere with human health or welfare, or produce other harmful environmental effects. Air pollution always consists of a whole range of pollutants, gaseous and particular alike. Common pollutants which are major public health concern include particulate mass and some gases like ozone, nitrogen oxides, sulphur oxide, and carbon monoxide. The sources of these pollutants include household combustion devices, motor vehicles, industrial facilities, forest fires and pesticides.
What is pollution? Pollution is the contamination of our environment due to unclean things that are produced by ourselves. There are several kind of pollution. They include land pollution, water pollution, air pollution, and noise pollution. In this essay, I am going to discuss about air pollution.
Natural causes of air pollution consist of volcanic eruptions, forest fires and other natural processes. However, these occurrences are not often seen and only contribute to a small amount of air pollution in the world. They create air pollutants such as ash and smoke which may give rise to harmful effects on the environment as well as the people. Human activity contributes to the bulk of air pollution. Outdoor air pollution can be caused by manufacturing, burning of fossil fuels, other forms of burning as well as smoking.
1.0 Introduction Air pollution refers to the condition in which the existence of toxic substances in the atmosphere, generated by various human activities such as industrialization and natural phenomenon occurrence such as volcanic eruptions, results in damaging effects on the welfare of human beings and the living environment. This natural phenomenon and human activities which resulting in air pollution can cause serious damaged to the ozone layer which cause the rise in the temperature of the earth. Based on Air Pollutants Index of Malaysia (APIMS) official website, it is stated that the methods in knowing the seriousness of the air pollution in a certain country is through air pollutant index (API). When the API increases, therefore there
Causes of Air pollution 1. Burning of Fossil Fuels: Sulfur dioxide emitted from the combustion of fossil fuels like coal, petroleum and other factory combustibles is one the major cause of air pollution. Pollution emitting from vehicles including trucks, jeeps, cars, trains, airplanes cause immense amount of pollution. We rely on them to fulfill our daily basic needs of transportation. But, there overuse is killing our environment as dangerous gases are polluting the environment.
If mercury comes into the air, it can weaken a child’s ability to learn. Another way that humans hurt the environment is through transportation. Carbon Dioxide is the biggest pollutant emitted from cars, planes, and power plants. Burning carbon and organic compounds produces Carbon Dioxide (“Air Pollution Causes”). Carbon Dioxide raises the temperature of the earth, otherwise known as global warming; over time, it has also made the ocean 30 percent more acidic, which effects all living things in the ocean.
Heavy metals, nitrates and plastic are toxins responsible for pollution. While water pollution is caused by oil spill, acid rain, urban runoff. The reason behind air pollution is because of various gases and toxins released by industries and factories and combustion of fossil fuels. Thermal pollution is rise in the temperature in the ecosystem due to the release of excessive heat energy into the environment by artificial methods or natural disasters. When someone thinks of pollution, the idea of thermal pollution usually does not come to mind.
These pollutants affect humans, animals, plants and atmosphere. Their effects are indeed many and wide-ranging. The excessive levels of pollutants cause a lot of damage to human and animal health. For example air pollution reduces the lung functioning, cause irritation of mouth, throat, eyes and nose, asthma, respiratory symptoms like coughing and wheezing.Air pollutants like sulphur dioxide, oxides of nitrogen etc increases the respiratory diseases and reduces the energy level.Similarly water pollution causes many waterborne diseases like amoebiasis,hookworm,giardiasis,ascariasis and typhoid. The polluted water can damage the nervous system, liver, DNA and kidney.
