Causes of Air Pollution

Air pollution is caused when air in the atmosphere is filled with particulate matter.
The largest source air of pollution in cities is from vehicle exhaust fumes.
Carbon monoxide is the largest air pollutant in the United States, and it’s number one source is from vehicle exhausts.
Carbon monoxide is a poisonous, odorless, colorless gas that is formed when burning fossil fuels such as coal, petroleum and natural gas.
Filters that are not changed regularly in your air conditioning units will accumulate dirt and cause the spread of pollutants in the air you breathe inside your home.
Chemicals and toxic pollutants likes sulfur dioxide, nitrogen oxides and carbon dioxide react with water molecules in the atmosphere to produce acid rain. These pollutants come from factories, automobiles and any industrial or manufacturing plants.
Another source of air pollution is from dust and dirt that goes airborne due to every day labor in the agricultural and construction industry. Dust is lifted from tractors working on fields, and from land clearing and general demolition in the construction industry.
Using household chemicals without adequate ventilation is a major source of indoor air pollution.
Volcanoes, dust storms, and forest fires are causes of natural air pollution.

Effects of Air Pollution

Air pollution causes irritation in the throat, nose, lungs and eyes. It causes breathing problems and aggravates existing health conditions such as emphysema and asthma.
Contaminated air reduces the body’s defenses and decreases the body’s capacity to fight other infections in the respiratory system.
Frequent exposure to polluted air increases the risk of cardiovascular disease. Breathing air that is filled with fine particulate matter can induce hardening of the arteries, triggering cardiac arrhythmia or even a heart attack.
People who exercise outdoors are susceptible to the adverse effects of air pollution because it involves deeper and faster breathing.
Acid rain contains hydrogen ions, which can damage trees, crops, harm marine animals and induce corrosion in metals. Smog causes harmful health effects in humans and animals. Studies have shown signs of black lung disease in dolphins of due to high concentrations of carbon particles in the air.
People afflicted with heart disease, children and older people are more sensitive to air pollution.

Air pollution can further be classified into two sections- Visible air pollution and invisible air pollution. Another way of looking at Air pollution could be any substance that holds the potential to hinder the atmosphere or the well being of the living beings surviving in it. The sustainment of all things living is due to a combination of gases that collectively form the atmosphere; the imbalance caused by the increase or decrease of the percentage of these gases can be harmful to survival.

1. Respiratory and heart problems: The effects of Air pollution are alarming. They are known to create several respiratory and heart conditions along with Cancer, among other threats to the body. Several million are known to have died due to direct or indirect effects of Air pollution. Children in areas exposed to air pollutants are said to commonly suffer from pneumonia and asthma.

2. Global warming: Another direct effect is the immediate alterations that the world is witnessing due to Global warming. With increased temperatures worldwide, increase in sea levels and melting of ice from colder regions and icebergs, displacement and loss of habitat have already signalled an impending disaster if actions for preservation and normalization aren’t undertaken soon.

3. Acid Rain: Harmful gases like nitrogen oxides and sulfur oxides are released into the atmosphere during the burning of fossil fuels. When it rains, the water droplets combine with these air pollutants, becomes acidic and then falls on the ground in the form of acid rain. Acid rain can cause great damage to human, animals and crops.

4. Eutrophication: Eutrophication is a condition where a high amount of nitrogen present in some pollutants gets developed on sea’s surface and turns itself into algae and adversely affect fish, plants and animal species. The green coloured algae that are present on lakes and ponds is due to the presence of this chemical only.

5. Effect on Wildlife: Just like humans, animals also face some devastating effects of air pollution. Toxic chemicals present in the air can force wildlife species to move to a new place and change their habitat. The toxic pollutants deposit over the surface of the water and can also affect sea animals.

6. Depletion of Ozone layer: Ozone exists in earth’s stratosphere and is responsible for protecting humans from harmful ultraviolet (UV) rays. Earth’s ozone layer is depleting due to the presence of chlorofluorocarbons, hydrochlorofluorocarbons in the atmosphere. As ozone layer will go thin, it will emit harmful rays back on earth and can cause skin and eye-related problems. UV rays also have the capability to affect crops.
