Air Pollutants: Types, Sources, Effects and Control of Air Pollutants
Sources of Air Pollution
by Puja Mondal
Sources of air pollution refer to the various locations, activities or factors which are responsible for the releasing of pollutants in the atmosphere. These sources can be classified into two major categories which are:
Anthropogenic sources (human activity) mostly related to burning different kinds of fuel:
i. “Stationary Sources” include smoke stacks of power plants, manufacturing facilities (factories) and waste incinerators, as well as furnaces and other types of fuel-burning heating devices.
ii. “Mobile Sources” include motor vehicles, marine vessels, aircraft and the effect of sound etc.
iii. Chemicals, dust and controlled burn practices in agriculture and forestry management. Controlled or prescribed burning is a technique sometimes used in forest management, farming, prairie restoration or greenhouse gas abatement. Fire is a natural part of both forest and grassland ecology and controlled fire can be a tool for foresters. Controlled burning stimulates the germination of some desirable forest trees, thus renewing the forest.
iv. Fumes from paint, hair spray, varnish, aerosol sprays and other solvents.
v. Waste deposition in landfills, which generate methane. Methane is not toxic; however, it is highly flammable and may form explosive mixtures with air. Methane is also an asphyxiate and may displace oxygen in an enclosed space. Asphyxia or suffocation may result if the oxygen concentration is reduced to below 19.5% by displacement.
vi. Military, such as nuclear weapons, toxic gases, germ warfare and rocketry.
Natural sources:
i. Dust from natural sources, usually large areas of land with little or no vegetation.
ii. Methane emitted by the digestion of food by animals, for example cattle.
iii. Radon gas from radioactive decay within the Earth’s crust. Radon is a colourless, odourless, naturally occurring, radioactive noble gas that is formed from the decay of radium. It is considered to be a health hazard. Radon gas from natural sources can accumulate in buildings, especially in confined areas such as the basement and it is the second most frequent cause of lung cancer, after cigarette smoking.
iv. Smoke and carbon monoxide from wildfires.
v. Volcanic activity, which produce sulphur, chlorine, and ash particulates
Causes Of Air Pollution
by Jerry Coffey on December 4, 2010
There are several main causes of air pollution, the vast majority of them can be attributed to man. This article will give you a definition of air pollution and list some of the top causes and how each one contributes to the contamination in the atmosphere.
Air pollution is the introduction into the atmosphere of chemicals, particulates, and biological matter that cause harm to humans, other living organisms, or cause damage to the natural environment. Stratospheric ozone depletion (contributed to air pollution) has long been recognized as a threat to human health as well as to the Earth’s ecosystems. The Earth is capable of cleaning itself of a certain level of pollution, but man-made pollutant have become too numerous for the Earth’s natural mechanisms to remove. We are seeing the results of this overload in the form of acid rain, smog, and the variety of health problems that can be contributed to our environment.
One of the main causes of air pollution is manufacturing. This source of pollution spews particulate matter and chemicals into the atmosphere. The exhaust from a factory includes, sulfur oxides, nitrogen oxides, carbon monoxide and dioxide, as well as volatile organic compounds and particulates. There is not an area of the Earth’s atmosphere or an ecosystem that has not been altered by the long term effects of the pollution created by manufacturing. Strides have been made to filter the material coming from manufacturing plants, but it may take the Earth millennia to completely recover from the damage already done.
As the list of causes of air pollution goes this next offender is number one. The burning of fossil fuels is a part of the everyday life of every human on the planet. We burn fossil fuels in our cars, fossil fuel is burned to extract fossil fuel from the Earth, and fossil fuel is used to process fossil fuel into its individual components. Every step of the way releases sulfur and nitrogen oxides, carbon monoxide, heavy metals, and particulates into the air. Each step in the process increases the number of asthma cases in the world, raises a person’s chance of having cancer, and increases the chance that your child will be born with congenital defects.
The Earth itself contributes to air pollution through volcanic eruptions, wildfires, and other natural process, but it is capable of recovering from those sources. As humans continue to industrialize with a dependence on fossil fuels, we continue to put our planet’s future in jeopardy and shorten the longevity of our species.

According to Jerry Coffey and Puja Mondal, There are several causes of air pollution. Both of them believe that manufacturing , burning of fossil fuels, smoke and carbon monoxide from wildfires and volcanic activity are causes of air pollution. However, unlike Jerry Coffey , Puja Mondal climes that mobile sources, waste deposition in landfills, military, dust from natural sources, methane emitted by the digestion of food by animals, radon gas from radioactive decay within the Earth’s crust
Opinion
In my view, I think that mainly factor of air pollution caused by human, as population increases, housing, it must be increased. Production was increased to accommodate the needs of the population. Example, The deforestation to habitat construction and bring to a building material so, forest decreased and air pollution increases, and all of these as a result of natural disasters. In conclusion, I think that human activities are the main cause of air pollution.
