Definition Of Air Pollution

Air pollution occurs when the air contains gases, dust, in harmful amounts. That is, amounts which could be harmful to the health or comfort of humans and animals or which could cause damage to plants and materials.

The substances that cause air pollution are called pollutants. Pollutants that are pumped into our atmosphere and directly pollute the air are called primary pollutants. Primary pollutant examples include carbon monoxide from car exhausts and sulfur dioxide from the combustion of coal.

Further pollution can arise if primary pollutants in the atmosphere undergo chemical reactions. The resulting compounds are called secondary pollutants. Photochemical smog is an example of this.

Transportation

The effect of air pollution for human

Air pollution can affect our health in many ways with both short-term and long-term effects.

short-term effects include irritation to the eyes, nose and throat, and upper respiratory infections such as bronchitis and pneumonia. Other symptoms can include headaches, nausea, and allergic reactions. Short-term air pollution can aggravate the medical conditions of individuals with asthma and emphysema.

Long-term health effects can include chronic respiratory disease, lung cancer, heart disease, and even damage to the brain, nerves, liver, or kidneys. Continual exposure to air pollution affects the lungs of growing children and may aggravate or complicate medical conditions in the elderly. It is estimated that half a million people die prematurely every year in the United States as a result of smoking cigarettes.

Air pollution does not only damage the air; it also damages environments on Earth’s surface and their inhabitants. plants and animals are harmed by air pollution. Sometimes it is the pollutants themselves that cause damage. Other times pollutants combine and change the resources that plants and animals depend upon such as water, soil, and nutrients. Read on to learn more about the ways that air pollutants can damage environments and the living things within them.
