- Air Pollution : Clean Air;
Air pollution is the mixing of foreign substances to the whole atmospheric air. Harmful and toxic gases emitted by the industries and motor vehicles causing huge damage to the living organisms whether plants, animals or human beings. Some of the natural and various human resources are causing air pollution.
However, most of the air pollution sources are stem out of the human activities like burning fossil fuels, coal and oil, release of harmful gases and substances from factories and motor vehicles. Such harmful chemical compounds like carbon dioxide, nitrogen oxides, carbon monoxide, sulphur dioxide, solid particles, etc are getting mixed to the fresh air.
Other source of the air pollution is decomposition of garbage in landfills and disposal of solid wastes which are emitting methane gas dangerous to the health. Rapid growth of population, industrialization, increased use of automobiles, aeroplanes, etc has made this issue a serious environmental problem.
The air we breathe every moment is full of pollutants going to our lungs and whole body through blood causing uncountable health problems. Polluted air is causing damage to the plants, animals and human beings in many direct and indirect ways. If the environmental protection policies are not followed seriously and strictly, the increasing level of air pollution may increase up to one million tons annually in the recent decades. When the fresh air gets polluted by means of dust, toxic gases, smoke, motor vehicles, mills and factories, etc called air pollution.
As we all know that fresh air is the most important element of the healthy life, we need to think that what happens if whole atmospheric air gets dirty. First of all air pollution is the matter of great regret for the whole human fraternity. Some of the big reasons of the air pollution are use of poisonous fertilizers, insecticides, pesticides in the agricultural sectors by the innocent farmers in order to increase the crop production.
Released chemicals and hazardous gases ammonia from such fertilizers are getting mixed into the fresh air and causing air pollution. Burning of fossil fuels such as coal, petroleum including other factory combustibles are the major causes of air pollution. Variety of smoke emissions from the automobiles such as cars, buses, motorcycles, trucks, jeeps, trains, aeroplanes, etc are also causing air pollution.
Increasing number of industries is causing release of toxic industrial smokes and harmful gases like carbon monoxide, organic compounds, hydrocarbons, chemicals, etc from the factories and mills to the environment. Some indoor activities of the people like innocent use of cleaning products, washing powders, paints etc emits various toxic chemicals to the air. The ever increasing level of air pollution also enhances its negative and harmful effects to the health of living beings. Air pollution is causing global warming to increase because of increasing atmospheric temperature due to the increasing level of green house gases.
Such green house gases again causing green house effect and forcing sea levels to increase, glaciers to melt, weather to change, climate to change, etc. Increasing air pollution is causing many lethal diseases cancer, heart attack, asthma, bronchitis, kidney diseases, etc and death to occur.
Various important animals and plants species have been destroyed completely from this planet. Increasing level of harmful gases in the environment are causing the occurrence of acid rain and depleting the ozone layer.
Increasing concentration of the harmful and toxic materials in the fresh air of the atmosphere is causing air pollution. Variety of foreign particles, toxic gases and other pollutants released from various human activities are affecting the fresh air which has adverse effect to the living beings like human beings, animals and plants.
The level of air pollution depends on the type and amount of pollutants released from various sources. Topographical and meteorological conditions are increasing the spread and concentration of the pollutants. Variety of raw materials used in the manufacturing process in industries is increasing the type and quantum of emissions of harmful gases. Increasing population density is demanding the need of more industrialization which ultimately causes air pollution.
Air Pollutants like harmful liquid droplets, solids particulates, and toxic gases oxides of carbon, halogenated and non-halogenated hydrocarbons, nitrogen and sulphur gases, suspended inorganic particulate matters, inorganic and organic acids, bacteria, viruses, insecticides etc which are generally not the constituents of fresh air are very hazardous to the plant and animal life.
There are two types of air pollution sources which are natural sources and man-made sources. Some natural sources of the air pollution are like volcanic eruptions, volcanoes ashes, carbon dioxide, smokes, dust and other gases , deflation of sands, dusts, salts spray from seas and ocean, soil particles, storms, forest fires, cosmic particles, rays, bombardment of asteroid materials, comets, pollen grains, fungal spores, viruses, bacteria, etc. Man-made sources of the air pollution are industries, agriculture, power plants, automobiles, domestic sources, etc.source link
Air Pollution Causes, Effects & Solutions: The Definitive Resource
Some of the air pollutants from the man-made sources are like smokes, dust, fumes, particulate matters, gases from kitchen, domestic heating, emissions from different vehicles, use of insecticides, pesticides, herbicides, heat created from power plants, smokes, fly ash, etc. Because of the increasing number of air pollutants, it has been divided into two types such as primary pollutants and secondary pollutants.
Primary pollutants are those affecting the fresh air directly and emitted from smoke, ash, dust, fumes, mist, spray, inorganic gases, carbon dioxide, carbon monoxide, sulphur dioxide, hydrogen sulphide, ammonia, nitric oxide and radioactive compounds. Secondary pollutants are those affecting the air indirectly by chemical interactions to the primary pollutants and other atmospheric constituents such as sulphur-trioxide, ozone, hydrocarbons, nitrogen dioxide, etc.
The get together effort of the human beings all over the world may help in controlling the level of air pollution. Chemicals like sulfur dioxide are released during the burning process, which travel straight into the atmosphere. These types of pollutants react with water molecules to yield something known as acid rain.
This is one of the reasons that alternative energy sources, such as nuclear, solar, and wind are being explored in greater detail. They tend to release much less pollutants into the environment to produce equivalent amounts of energy.
Similar to exhaust being released from vehicles, heavier machinery located inside big factories and industrial plants also emit pollutants into the air. Industrial plants can be found pretty much everywhere in the world, so the spreading of air pollution is basically global. On a daily basis, dirt and dust is kicked up into the atmosphere from excavating and demolition type construction activities.
Switching the focus to agricultural activities, ammonia is a frequent byproduct that just so happens to be one of the most dangerous gases in our environment. There are also plenty of nasty chemicals that get placed into the atmosphere from pesticides and fertilizers, which are being used at increasingly higher rates. When people think pollution, they almost always blame other people.
Volcanoes, forest fires, and dust storms are nature-born events that dump massive amounts of air pollution into the environment. Common household chemicals, notably bleach, without proper ventilation is a primary source of indoor air pollution. Smoking tobacco through the use of cigarettes and cigars also releases toxic pollutants into the air. There are many different types of effects that air pollutants can cause. Earlier on, you learned about the Ozone layer and its role in protecting our planet. Air pollution directly accelerates the rate at which global warming happens by depleting the Ozone layer.
Global warming refers to the increased temperatures Earth continues to experience. These higher temperatures lead to the melting of the polar ice caps and icebergs, which elevates sea levels and creates concern for the human race. Air pollution is known to cause irritation in the eyes, lungs, nose, and throat.
Essay on Air Pollution
It creates respiratory problems and exacerbates existing conditions such as asthma and emphysema. When continually exposed to air pollution, humans become at higher risk for cardiovascular disease. Air filled with toxins can have a number of adverse effects on the arteries, and have even been a contributor to heart attacks. Most diseases and conditions that humans are susceptible to, animals are as well.
Air pollution creates many of the same issues that humans face. Heavily polluted areas force inhabitants to seek new homes, which can negatively impact the ecosystem. When air pollution, specifically sulfur oxides and nitrogen oxides, are released into sky through fossil fuel burning, it creates the phenomenon known as acid rain. Water, high in the atmosphere, combines with these chemicals and becomes acidic in nature.
It then scatters the ground, disguised as normal rainfall. Understanding the causes and effects proves to be important so that we can determine how best to combat it. Reducing the use of fossil fuel powered automobiles is clearly something that can help. Same with finding unique ways to reduce energy consumption. As a leading contributor to air pollution, it only makes sense that a vehicle-based solution appears first on this list. One way to do this is by switching to a hybrid vehicle, or better yet, one that runs on fully electric. Other ways include taking public transportation, carpooling with friends and colleagues, or even riding a bike to your destination.
