Types of Pollutants
Primarily Air Pollutants
Secondary Air Pollutants
It can be caused by primary sources or secondary sources.
Primarily Air pollutants
The pollutants that are a direct result of the process can be called primary pollutants.
Primarily air pollutants
A classic example of a primary pollutant
sulfur-dioxide emitted from factories
It are the ones that are caused by the inter mingling and reactions of primary pollutants.
Secondary pollutants
Smog created by the interactions of several primary pollutants
secondary pollutant.
Causes of air pollution
Burning of fossil fuels Agricultural activities Acid rain Eutrophication Effect on wildlife Depletion of ozone layer
It is emitted from the combustion of fossil fuels like coal, petroleum and other factory combustibles is one the major cause of air pollution.
Sulfur dioxide
Pollution emitting from vehicles including trucks, jeeps, cars, trains, airplanes cause immense amount of pollution. We rely on them to fulfill our daily basic needs of transportation. But, there overuse is killing our environment as dangerous gases are polluting the environment.
Burning of fossil fuel
It caused by improper or incomplete combustion and generally emitted from vehicles is another major pollutant along with __, that is produced from both natural and man made processes.
Carbon monoxide
Nitrogen Oxides
It is a very common by product from agriculture related activities and is one of the most hazardous gases in the atmosphere.
Ammonia
Use of __ in agricultural activities has grown quite a lot. They emit harmful chemicals into the air and can also cause ___
insecticides, pesticides and fertilizers
Water pollution
Harmful gases like __ and __ are released into the atmosphere during the burning of fossil fuels. When it rains, the water droplets combines with these air pollutants, becomes acidic and then falls on the ground in the form of __.
Nitrogen oxide
Sulfur oxide
Acid rain
It can cause great damage to human, animals and crops.
Acid rain
It is a condition where high amount of nitrogen present in some pollutants gets developed on sea’s surface and turns itself into algae and and adversely affect fish, plants and animal species.
Eutrophication
The green colored algae that is present on lakes and ponds is due to presence of this chemical only.
Eutrophication
Just like humans, animals also face some devastating affects of air pollution.
Effect on wildlife
Toxic chemicals present in the air can force wildlife species to move to new place and change their habitat. The toxic pollutants deposit over the surface of the water and can also affect sea animals
Effect on wildlife
Ozone exists in earth’s stratosphere and is responsible for protecting humans from harmful ultraviolet (UV) rays.
Depletion of Ozone layer
Earth’s ozone layer is depleting due to the presence of __ 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. __also have the capability to affect crops.
chlorofluorocarbons, hydro chlorofluorocarbons
UV rays
When you try to study the sources of Air pollution, you enlist a series of activities and interactions that create these pollutants. There are two types of sources that we will take a look at:
Natural sources and Man-made sources.
It include dust carried by the wind from locations with very little or no green cover, gases released from the body processes of living beings
Natural sources
__ from humans during respiration, __ from cattle during digestion, __ from plants during Photosynthesis
Carbon dioxide
Methane
Oxygen
Smoke from the combustion of various inflammable objects, volcanic eruptions etc along with the emission of polluted gases
Natural resources
Smoke again features as a prominent component.
Manmade sources
The smoke emitted from various forms of combustion like in __.
bio mass, factories, vehicles, furnaces etc
Waste used to create landfills generate __, that is harmful in several ways. The reactions of certain gases and chemicals also form harmful fumes that can be dangerous to the well being of living creatures.
methane
Solution of air pollution
Use public mode of transportation
3 Rs
Conserve energy
Encourage people to use more and more public modes of transportation to reduce pollution. Also, try to make use of car pooling. If you and your colleagues come from the same locality and have same timings you can explore this option to save energy and money.
Use public mode of transportation
Switch off fans and lights when you are going out.
Conserve energy
Large amount of fossil fuels are burnt to produce electricity. You can save the environment from degradation by reducing the amount of fossil fuels to be burned.
Conserve energy
Do not throw away items that are of no use to you. In-fact reuse them for some other purpose. For e.g. you can use old jars to store cereals or pulses.
Understand the concept of Reduce, Reuse and Recycle
Clean energy technologies like solar, wind and geothermal are on high these days.
Emphasis on clean energy resources
Governments of various countries have been providing grants to consumers who are interested in installing solar panels for their home. This will go a long way to curb air pollution.
Emphasis on clean energy resources
