Write an article on air pollution highlighting its causes and effects
Answers
Answer:
Air pollution consists of chemicals or particles in the air that can harm the health of humans, animals, and plants. It also damages buildings. Pollutants in the air take many forms. They can be gases, solid particles, or liquid droplets.
Sources of Air Pollution
Pollution enters the Earth's atmosphere in many different ways. Most air pollution is created by people, taking the form of emissions from factories, cars, planes, or aerosol cans. Second-hand cigarette smoke is also considered air pollution. These man-made sources of pollution are called anthropogenic sources.
Some types of air pollution, such as smoke from wildfires or ash from volcanoes, occur naturally. These are called natural sources.
Air pollution is most common in large cities where emissions from many different sources are concentrated. Sometimes, mountains or tall buildings prevent air pollution from spreading out. This air pollution often appears as a cloud making the air murky. It is called smog. The word "smog" comes from combining the words "smoke" and "fog."
Large cities in poor and developing nations tend to have more air pollution than cities in developed nations. According to the World Health Organization (WHO), some of the worlds most polluted cities are Karachi, Pakistan; New Delhi, India; Beijing, China; Lima, Peru; and Cairo, Egypt. However, many developed nations also have air pollution problems. Los Angeles, California, is nicknamed Smog City.
causes of air pollution in points are listed below i
1. Particulate Matter
Air pollution is characterised by the presence of particulate matter in the air of the atmosphere.
2. Poisonous Gas
Air is also said to be polluted when there is a presence of poisonous gases in the air we breathe.
3. Emission from Vehicles
The vehicle exhaust fumes in cities form the largest source of air pollution.
Carbon monoxide which is the principle bearer of air pollution is emitted from the exhaust of the vehicles.
4. Combustion of Fossil Fuels
Burning of fossil fuel leads to the formation of these poisonous odourless colourless gas called carbon monoxide.
Carbon monoxide is an extremely harmful gas.
5. Pollution From Air Conditioners
The filters in air conditioners when not changed regularly combines with air along with its dirt and pollutants leading to the pollution inside house.
This makes us breathe disease causing air inside our houses too.
6. Dust & Dirt
Air Pollution from dust and dirt is also a popular form of air pollution.
Every day labour in agricultural and construction industry lifts up dirt and dust that goes airborne in the atmosphere leading to air pollution.
Dust lifted from tractors in fields and also land clearing and general demolition in the construction field.
7. Household Pollution
Household chemicals that is being used without proper ventilation is also a major source of indoor air pollution.
And this type of indoor air pollution is very harmful for babies and infants.
8. Pollution from Natural Events
Natural events like volcanic eruption, dust storms and forest fires are natural causes of air pollution.
9. Deforestation
Trees are responsible for absorption of many harmful gases like carbon dioxide, carbon monoxide etc and returning oxygen in exchange.
Cutting down of these trees leads to lack of absorption of these gases.
Abundance of these gases causes global warming
10. Pollution from Factories
The end products of certain factories are harmful gases like carbon monoxide, nitrogen oxide.
These factories carelessly excrete these gases in the atmosphere contributing to air pollution.
Answer:
Explanation:
Air pollution
Air pollution refers to the release of pollutants into the air that are detrimental to human health and the planet as a whole.
Air pollution is caused by solid and liquid particles and certain gases that are suspended in the air. These particles and gases can come from car and truck exhaust, factories, dust, pollen, mold spores, volcanoes and wildfires. The solid and liquid particles suspended in our air are called aerosols.
Effects On Humans
People experience a wide range of health effects from being exposed to air pollution. Effects can be broken down into short-term effects and long-term effects.
Short-term effects, which are temporary, include illnesses such as pneumonia or bronchitis. They also include discomfort such as irritation to the nose, throat, eyes, or skin. Air pollution can also cause headaches, dizziness, and nausea. Bad smells made by factories, garbage, or sewer systems are considered air pollution, too. These odors are less serious but still unpleasant.
Long-term effects of air pollution can last for years or for an entire lifetime. They can even lead to a person's death. Long-term health effects from air pollution include heart disease, lung cancer, and respiratory diseases such as emphysema. Air pollution can also cause long-term damage to people's nerves, brain, kidneys, liver, and other organs. Some scientists suspect air pollutants cause birth defects. Nearly 2.5 million people die worldwide each year from the effects of outdoor or indoor air pollution.
Ways to reduce pollution
Anybody can take steps to reduce air pollution. Millions of people every day make simple changes in their lives to do this. Taking
instead of driving a car, or riding a bike instead of traveling in carbon dioxide-emitting vehicles are a couple of ways to reduce air pollution. Avoiding aerosol cans, recycling
instead of burning them, and not smoking cigarettes are others.
