In general, any substance introduced by the people into the atmosphere which has a damaging effect on the living organisms as well as on the environment is considered as air pollution. Another perspective of looking at air pollution could be through the gases or substances that hold the potential to hinder the atmosphere or the well-being of the living beings surviving in it. The sustainability of all living organisms is due to a combination of gases that collectively form the atmosphere, and hence the imbalance caused by the change in the percentage of these gases or substances can be harmful to survival.
Types of Pollutants
They are separated into two categories:
Outdoor :
The pollutants outside the built environment fall under this category.
Examples include:
Fine particles produced by the burning of fossil fuels (i.e. the coal and petroleum used in traffic and energy production)
Noxious gases (sulfur dioxide, nitrogen oxides, carbon monoxide, chemical vapours, etc.)
Ground-level ozone (a reactive form of oxygen and a primary component of urban smog)
Tobacco smoke
Indoor :
The particulates, carbon oxides and other pollutants carried by the indoor air or dust fall under this category.
Examples include:
Gases (carbon monoxide, radon etc.)
Household products and chemicals
Building materials (asbestos, formaldehyde, lead etc.)
Outdoor indoor allergens (cockroach and mouse dropping, etc.)
Tobacco smoke
Mould and pollens
Indoor Air Quality(IAQ)
Indoor air quality refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. IAQ can be affected by gases (including carbon monoxide, radon, volatile organic compounds), particulates, microbial contaminants (mold, bacteria), or any mass or energy stressor that can induce adverse health conditions. Source control, filtration and the use of ventilation to dilute contaminants are the primary methods for improving indoor air quality in most buildings.
Causes of Air Pollution
In order to understand the contributing causes of air pollution, we first need to understand the nature of pollutants swirling around us. Where do these air pollutants come from?
Air pollutants can either be the primary sources or the secondary sources. The pollutants that are a direct result of various processes are referred to as primary pollutants. A few examples of primary pollutants are the carbon-dioxide gas emitted from vehicle exhaust, and the sulfur dioxide emitted from factories. Secondary pollutants are the ones which result from the intermingling and reactions of the aforementioned primary pollutants. For instance, the smog created when the crackers are burst in excess or when there is too much vehicle exhaust due to traffic is known to be as a secondary pollutant.
Let’s have a look on major contributors to air pollution:
Burning of Fossil Fuels: Sulfur dioxide emitted from the combustion of fossil fuels like coal, petroleum and other factory combustibles are one of the major cause of air pollution. Pollutants emitted from vehicles further contribute to the degradation of the environment. Carbon Monoxide produced by the incomplete combustion of fuel is another major pollutant along with the Nitrogen Oxides, that are produced from both natural and man-made processes.
Agricultural Activities: Ammonia is a very common byproduct of the agriculture-related activities and is one of the most hazardous gases in the atmosphere. The use of insecticides, pesticides and fertilizers in agriculture also leads to the emission of harmful chemicals causing pollution.
Exhaust from Factories and Industries: Manufacturing industries and petroleum refineries release a large amount of carbon monoxide, hydrocarbons, organic compounds and chemicals into the air thereby depleting the quality of air.
Mining Operations: During the process of mining, huge volumes of dust and other chemicals are released into the air causing massive air pollution and leading to deteriorating health conditions of mining workers and nearby residents.
Indoor Air Pollution: Household cleaning products, painting supplies etc. emit toxic chemicals in the air while causing air pollution.
Suspended Particulate Matter: Popular by its acronym SPM, it is another cause of air pollution. While referring to the particles afloat in the air, the SPM is usually caused by dust, combustion etc.
Effects of Air Pollution
Effects on Human Health
Haven’t you ever coughed when a truck drove past you belching out its sooty exhaust? Instinctively, you cough to clear your lungs and protect your body, and you might even cover your face with your handkerchief or sleeve to filter the air until it feels safe to breathe deeply again.
Air pollution can severely harm the health of people and animals, damage plants or stop them from growing properly.
