Other planets have sunlight, but the Earth is the solitary planet we are familiar with that has air and water. Without air and water, the Earth would be not capable to carry on life. A diverse community of plant and animal life has thrived on this planet for millions of years, continued by the sun and supported by the soil, water and air. With greater than ever urbanization and industrialization, humans in progress to release more wastes into the atmosphere than nature possibly will cope with which has resulted in Air pollution.

The occurrence of wastes in the atmosphere of one or additional contaminants in excellence and for long period is harmful, or tends to be damaging, to human health or wellbeing, animal or plant life. It is the corruption of air by the release of harmful substances. Air pollution can cause health problems and it can also smash up the atmosphere and material goods. It has caused thinning of the defensive ozone layer of the atmosphere, which is most important to climate change.

Modernization and improvement have led to air getting more and more contaminated over the years. Industries, vehicles, increase in the population, and urbanization are some of the most important factors in charge for air pollution. The following industries are in the midst of those that give off a great deal of pollutants into the air: thermal power plants, cement, steel, refineries, petrol chemicals, and mines.

Air pollution results from a multiplicity of causes, not all of which are within human control. Dust storms in desert areas and smoke from forest fires and grass fires have a say to chemical and particulate pollution of the air. The source of pollution may be in one country but the collision of pollution may be felt in another place. The innovation of pesticides, where they have by no means been used, suggests the degree to which aerial transport can carry pollutants from one place to another.

Since after that, supplementary pollution has been added to the air by industrial, commercial and domestic sources. As these sources are more often than not found in major cities, the gases that are formed are usually concentrated in the air around them. It is when these intense gases go beyond safe limits that we have a pollution problem. Nature can no longer manage air pollution without the hard work of the over-increasing and existing people.

Health Effects of Air Pollution

Air pollution is caused by both natural and man-made sources. Major synthetic sources of ambient air pollution consist of industries, automobiles, and power production. In indoor environments, tobacco smoke and burning of solid fuels for cooking are the most important sources. In addition, structure material, furniture, carpeting, and insecticides can also be noteworthy sources of chemical and biological pollutants indoors.

Fuel fire is the most important source of a large adds up to health-damaging air pollutants. Air pollution has both severe and never-ending effects on human health. Health effects range anywhere from minor irritation of eyes and the upper respiratory system to persistent respiratory ailment, heart disease, lung cancer, and death. Air pollution has been shown to reason acute respiratory infections in children and chronic bronchitis in adults. It has also been shown to make worse the condition of people with preexisting heart or lung disease. Among asthmatics, air pollution has been shown to fan the flames of the incidence and severity of attacks. Both short-term and long-term exposures have also been associated with untimely mortality and reduced life anticipation.

Health impact of air pollution depends on the pollutant type, its absorption in the air, length of disclosure, other pollutants in the air, and individual helplessness. In cities, for instance, poor tend to live and work in most heavily polluted areas, and in rural areas poor are more likely to cook with dirtier fuels. In some countries, air quality principles tend to be more negligent around industrial areas in cities, where many poor tend to live in against the law resident settlements. Poor also tend to be more half-starved, more likely to go through ill health and disease, and have less access to health care.

Although, even at much concentrated levels, air pollution continues to make threats on public health. Several factors have a say to the worsening air pollution levels in developing-countries, including rapid growth in inner-city population, increasing industrialization, and rising demands for energy and motor vehicles. Other factors, such as poor ecological regulation, less resourceful technology of production, jam-packed roads, and age and poor safeguarding of vehicles, also add to the problem.

A voyage in the right direction to control the air pollution will also reduce its catastrophic impact on the future generations. You and I share equal liability to save our environment and put an end to the existing disastrous conditions in the environment.

Effects Of Air Pollution

Air pollution has harmful effects on people, animals and plant-life from corner to corner of the globe. Every time we breathe in, we take hazardous air pollutants into our bodies. These pollutants can cause short-term special effects such as eye and throat irritation. More distressing, on the other hand, are the long-term effects such as cancer and damage to the body’s resistant, neurological, reproductive and respiratory systems. Children, due to their size and the fact that they are in the process of developing, are at larger health associated possibility.
Air contamination is not just a “metropolis problem.” Many air pollutants are discrete over areas hundreds of miles from their source where they have an effect on many different ecosystems. These pollutants over and over again remain toxic in the environment for a very long time where they keep on affecting ponds, streams, fields and forests.
Most air pollution is the end result of energy burning up. In particular, the burning of fossil fuels to bring into being electricity or power transportation vehicles is the main cause of this serious, but avoidable, ecological vulnerability.

Motor vehicles are a most important source of air pollution. Emissions from cars and trucks throw in to international warming as well as causing severe health problems. Extracting, transporting and storing transportation fuels (gasoline) also pollutes the land and seas.
One noteworthy basis of pollution in urban, suburban and rural areas is the diesel engine. Off-road diesel powered vehicles, such as tractors and bulldozers, on average emit as much pollution as other automobiles.
Diesel school buses are on the whole intricate problem because they are operated in the surrounding area of children. Generally, children are at superior risk of health effects from pollution owing to their somewhat lower body weight and the truth that their organic systems are still on the increase.

Depending on wherever you live, your utility will use some amount of non-renewable fossil fuels to make electricity. These fuels, such as coal, oil and gas, give off pollution when burned at power generation amenities. Burning fossil fuels for electricity generation is the single supreme source of air. The electricity generation process produces many risky pollutants together with nitrogen oxides, sulfur oxides, hydrocarbons, dust, soot, smoke, and other balanced matter. These pollutants affect us and end result is serious health problems, including early death.

The effects of air pollution are felt in the home, in hastily developing city areas, and across national boundaries. Current trends are upsetting, but resolute efforts may trim down the grievous affect air pollution causes on the people.

Air Pollution And Diseases.

The diseases which multiply from one human being to a further human being are known as contagious diseases. The widespread cold, tuberculosis and whooping cough spread from one person to another through air. When an infected person coughs or sneezes the germs spread in the air. Always sneeze or cough into a handkerchief.

Pollution is an unwanted transform in the environment .It is caused by the let go or the addition of toxic substances in to the air, water or soil which might damage or kill the living organisms. The air surrounded us is contaminated by the release of smoke from cars, buses, lorries and factories. Some industries too are inclined to add heavy dust and poisonous chemicals to the air.

Air Pollution And Diseases Tobacco smoke: contains carbon monoxide; tar and nicotine which increases the risk of life threatening diseases such as heart attacks and can cause cancer.

Decomposing garbage and open sewers: Decomposing garbage gives out methane and open sewers emit hydrogen sulphide. Open garbage and sewers are breeding ground for mosquitoes, flies, germs and other harmful bacteria.

Poisonous gases: from factories and chemical plants cause respiratory diseases.

Acid Rain: When acidic gases dissolve in the moisture in the air, acids are formed. The acids fall on the earth as ‘acid rain’ and pollute the fresh water resources.

Mining activities: Rock particles, smelters, coal and mineral dust cause lung and respiratory ailments.

Carbon monoxide and lead: from exhausts of motor vehicles affect the brain and organs like kidney.

Ozone Depletion effect: CFCs destroy the protective ozone layer and let in harmful ultraviolet rays, causing skin cancer and affecting plant life.

Smoke from Burning fuels and oil rigs: Smoke is a mixture of soot and acidic gases. It causes global warming and impure air. Smoke contains harmful substances which causes cancer.

Green house effect: Increasing carbon dioxide in the atmosphere due to industrial activity and burning of fossil fuels traps more heat, changes the climate, melts the polar ice caps and submerges coastal areas.

Automobile exhaust: is one of the major sources of air pollution in big cities. The exhaust contains carbon dioxide, carbon monoxide, sulphur dioxide, lead, particulate matter and partially burned hydro carbons. They are called pollutants. All these pollutants are highly harmful to human health.

Asthma is caused by allergic reactions to pollutants in the air. Air pollution may show the way to several diseases in the human beings such as allergic reaction, asthma and lung diseases. Asbestosis is an allergic reaction to the occurrence of silica and asbestos in the air.

Plants suck in air in carbon dioxide and breathe out oxygen. Air pollution can be reduced by planting more trees in our neighborhood and being concerned of them.

Control Of Air Pollution

Our earth is surrounded by air on all sides. It is invisible and the area covered by air is called atmosphere. When the air gets dirty and is unhealthy to breathe it is called as Air pollution. The air gets polluted by the presence of dust particles .Many factors are responsible for air pollution.

Air Pollution can be controlled in the following ways:

The vehicles such as cars, scooters, auto rickshaws, trucks, buses etc that ply on the road are increasing drastically on a day to day basis. All these vehicles run on fuel like diesel or petrol. When the fuel from these vehicles burns in the engine, a lot of harmful smoke is released in the air. In big cities the number of auto vehicles is very high and thus large amount of smoke which is hateful to the nose, harmful to the brain and dangerous to the lungs is released. Smoke contains many poisonous gases due which lot of people suffer from dangerous diseases like asthma. It gets difficult for them to breathe. The polluted air even effect’s our eyes and causes irritation.

The emission level of all these auto vehicles should be checked regularly. Strict laws should be imposed to control air pollutions and the guilty should be fined. Old vehicles should be banned as the emission level is very high. Public vehicles like buses and auto rickshaws should be compulsorily made to use compressed natural gas. This fuel causes minimum pollution and this has already been made compulsory in metro cities like New Delhi, Mumbai, etc.

There are many factories in cities, which also causes air pollution and emit a lot of harmful gases like carbon dioxide and carbon monoxide from the chimneys. They are equally poisonous and harmful to human being and animals. To avoid this, manufacturing units should be located in industrial estates far away from the cities and more over tall chimneys should be used because it reduces the effect of air pollutions to the man kind. Due to the tall chimneys the harmful gases do not come in contact with people and get mixed in clouds.

Waste accumulation also pollutes the air, when people drop filth in open. Many fly and insects breed on them and sit on uncovered food which causes diseases like Diarrhea and Malaria. Sometime people burn waste material, which can be re-use or re-cycled. This practice adds to the problem of air pollution. To avoid this more trees should be planted, so that people get fresh, clean and more Oxygen. Cutting of tree should be completely banned.
