We cannot completely eliminate air pollutants from atmosphere but we can minimize the pollution load by two main methods:

1) By changing the raw material or methodology like replace coal in electricity production with biogas(it also helps in waste management) or use LPG etc.

We should produce electricity from other sources like atomic power and hydropower or in other words we should encourage the use renewable energy sources instead of non-renewable.

2) Use of air pollution control devices: Here we control the pollutants after they produced not like first method where we tried to avoid the production of pollutants.Devices or methods include

• Electrostatic Precipitator (ESP)
• Spray Dryer
• Dust collector
• Scrubber etc.

Conclusion: Change the fuel which generate more global warming gases( COx, NOx). Use appropriate equipments if their production is unavoidable.

Dear M. A. A. Al- Fatlawi

Kindly provide your views.

What is air pollution?

Air pollution is an undesirable and excessive addition of foreign materials to air which adversely alters its natural quality. It occurs due to the presence of undesirable solid or gaseous particles in the air, in quantities that are detrimental to human health or which could cause damage to plants and materials. Urbanization, industrialization, deforestation, vehicular exhaust etc are the main causes of air pollution.

How air pollution affects the human life?

Prolonged exposure to toxic pollutants from various sources affects the normal functioning of life. Elevated levels of nitrogen dioxide (NO2) and smog causes increase in incidence of allergic disorders such nausea, vomiting and and eye irritation. The toxic elements in the atmosphere are responsible for asthma, bronchitis emphysema and related respiratory disorders. Elderly people, infants, pregnant women and people with cardiac and respiratory diseases are vulnerable to air pollution.  Organic lead emitted from automobiles get absorbed in brain, liver, kidney and blood, causing convulsions, muscular paralysis, reduction in red blood cells (RBC) count and brain damage. Carbon monoxide (CO) combines with blood haemoglobin much faster than oxygen thus reducing the oxygen carrying capacity of the blood. It combines with haemoglobin more than 200 times faster than oxygen (O2). Carbon monoxide in heavy traffic causes headache, drowsiness and blurred vision. Exposure to air containing even 0.001% of carbon monoxide for several hours causes coma and even death. Sulphur dioxide (SO2) irritates the respiratory tissues. It also reacts with water in the atmosphere to form sulphur containing acids. The acids when inhaled affect the lungs.

Nitrogen oxides (NO & NO2) irritates lungs aggravates asthma or chronic bronchitis and increases susceptibility to respiratory infection like influenza. The continued inhalation of ozone causes chest pain, breathlessness and irritation of eye, nose and throat.

How to control air pollution?

One of the effective means of controlling air pollution is to have proper equipment in place. This includes devices for removal of pollutants from the flue gases through scrubbers, closed collection recovery systems, the use of dry and wet collectors, filters, electrostatic precipitation etc. 

Since plants are major sinks of carbon dioxide, hence ‘green belt’ plantation must be raised around industrial units and in urban areas. 

The forest cover should be protected, and deforested areas must be restored through reforestation programmes. 

In developing countries like India traditional use of fuelwood needs to be controlled. 

Since vehicles substantially contribute to air pollution, hence their engines needs to be redesigned in such a way that may minimize the emissions of pollutants. Installation of catalytic converter in vehicles should be made compulsory. 

Building of higher smoke-stacks facilitates the discharge of pollutants as far away from the ground as possible. Industries should be carefully located so as to minimize the effects of pollution after considering the topography and the wind direction.

Thanks Arvind Sir for your great Answer.

@ Pankaj Tomar

I agree with you sir but awareness about limited use of vehicles is also necessary to reduce air pollution.

Thanks again

Perhaps all the adult inhabitants of the world know how air pollution can be controlled and how s/ he is contributing in air pollution.

The thing required is initiative to control of the sources of production of dangerous gases and dusts.

Strong legislations to control such sources and production and its strong application is having the strongest role in controlling air pollution.

@ Shibabrata Pattanayak: Now we are facing problems and it will be very difficult to stay alive in near future.

Thanks Sir

In a thickly populated country like India, mass communication vehicles should be given priority.

But due to pressure of the car manufacturing sector, we are arranging easy loan facilities to purchase car by any people upto just above the poverty line. We are spending a huge amount of hard earned foreign money to purchase petroleum from Arabian countries.

In return?

We are destroying our environment.

How can you explain this policy matter otherwise?

No completely control air pollution. It is adversely affect on human health especially respiratory system.

Controlling air pollution

Reducing pollutants in the air is important for human health and the environment.

Poor air quality has harmful effects on human health, particularly the respiratory and cardiovascular systems.

Pollutants can also damage plants and buildings, and smoke or haze can reduce visibility.

Community

At the community level, you can reduce air pollutants by choosing to walk, cycle or take public transport rather than drive a car.

You can also keep your car in good condition and drive to reduce fuel consumption and minimise emissions.

You can buy items that have low-energy manufacture and use requirements, or which can be recycled.

Good urban design and planning can also reduce pollution by having cleaner, ‘greener’ choices for the public. These may include increasing walking and cycling paths and having urban ‘hubs’ where people work, play and shop locally, reducing their need to travel.

Farmers

Farmers can reduce air pollution by conducting hazard-reducing burning at times when smoke impacts are likely to be minimal.

Also, sugar cane can be harvested green, which removes the associated smoke impact.

Industry

Industries can use pollution control devices to remove pollutants by absorbing, filtering, diluting or dispersing them.

Government licensing and regulation are effective ways to minimise emissions from industry.

Industrial pollution control devices

These are some of the most common devices used to control industrial pollution.

Particle removal—cyclone

A cyclone works on the principle of creating a high-speed spiral airflow to remove particles. This spiral motion applies a centrifugal force on the particles.

The inertia of the particles forces them to the outside walls of the cyclone, where they fall to the bottom and are collected.

The speed of the airflow and the width of the cyclone influence particle removal—the smaller the diameter the more efficient the particle removal.

The conical section at the base of the cyclone gradually decreases the diameter of the spinning gas stream, resulting in better removal of smaller particles.

However, in practice, reducing the diameter increases the pressure drop across the cyclone. Combining several units together as a ‘multicyclone’ can prevent this.

Particle removal—electrostatic precipitator

The electrostatic precipitator works by removing particles and smoke from a gas stream using an electrostatic charge.

Dust particles travel past wires that have a high direct current (DC) voltage applied, which ionises the surrounding gas. This corona discharge causes the particles to pick up a small electrostatic charge.

An oppositely-charged plate attracts the particles, neutralises and retains them. A regular tapping (rapping) of the plates then physically removes the collected particles.

Introducing a water spray can reduce the electrical resistance of the dust particles, allowing them to accept the charge more easily.

Electrostatic precipitators are an efficient way of removing particles and do not cause a significant pressure drop across the unit.

Particle removal—bag filters

Bag filters use fabric bags to remove particles from dust-laden gas.

They can achieve high efficiencies for fine particles because of the build-up of particles on either the inside or outside surface of the bag depending on the design.

As dust builds up, the pressure across the bag increases, so the filters need regular cleaning. Usually bag filters work in tandem—one filter is working while the other filter is being cleaned.

Mechanical shaking, using a reverse airflow or a pulse of compressed air are used to dislodge the dust from the fabric surface, which then falls by gravity into a collection system.

Particle and gas removal—packed bed wet scrubber

A packed bed wet scrubber removes gaseous and particle contaminants from a gas stream.

It works by bringing the gas stream into contact with a scrubbing liquid (usually water).

The scrubbing liquid absorbs the gaseous pollutants, and the spray droplets physically capture the particles. 

The packed bed of non-reactive material gives a greater gas-to-liquid contact which improves the removal of particle pollutants.

Although the packed bed wet scrubber can remove gaseous and particle pollutants, the particular design makes it more efficient at one or the other.

Using certain scrubbing liquids can increase gaseous pollutant removal, e.g. using an alkaline liquid to remove acidic pollutants.

Trapping and treating droplets of the scrubbing liquid can allow it to be recycled.

Pollution is a daily and continuous damages done to our habitat and it can never be stopped however it can be minimized and managed first by creating awareness.

@ J. M. Koli: If government and we all together will trying to reduce the air pollution then definitely we can achieve pollution free atmosphere.

Like it or not, air pollution is imposing a great burden on the health care programs and its budgeting in all nations. The latest figures released by the World Health Organization reflect how serious air pollutants are and how challenging they are in programs intended for the health and well being of citizens all over the world.

@ Reza Biria : Exactly Sir..Everyone should take part to overcome this problem..

Thanks Sir..

Thank you Arvind Singh for full answer

The different types of pollution are:

•Air Pollution. Air pollution is the contamination of the natural air by mixing it with different pollutants such as harmful fumes and chemicals. ...

•Water Pollution. ...

•Soil Pollution. ...

•Noise Pollution. ...

•Radioactive Pollution. ...

•Light Pollution. ...

•Thermal Pollution. ...

•Visual Pollution.

REASON FOR AIR POLLLUTION: Most of this air pollution we cause results from the burning of fossil fuels, such as coal, oil, natural gas, and gasoline to produce electricity and power our vehicles. Carbon dioxide (CO2) is a good indicator of how much fossil fuel is burned and how much of other pollutants are emitted as a result.

PREVENTIONS:

A. The best way to reduce the levels of carbon dioxide in the air is to use energy more efficiently and to reduce the combustion of fossil fuels by using alternative energy sources (e.g., nuclear, wind, tidal, and solar power).

1.Reduce the number of trips you take in your car.

2.Reduce or eliminate fireplace and wood stove use.

3.Avoid burning leaves, trash, and other materials.

4.Avoid using gas-powered lawn and garden equipment.

5.Stop smoking or at least follow the “No Smoking” sign.

6.Use unleaded gasoline in your cars.

7.Keep your car properly maintained to keep it in good running condition to avoid smoke emissions.

8.Share a ride or engage in car pooling.

@ Ahsan Siddiqui: Thanks sir,We should use alternative energy sources (e.g., nuclear, wind, tidal, and solar power) in place of fossil fuels.

Thanks @ Hassan Nima for giving a good solution, "At the community level, you can reduce air pollutants by choosing to walk, cycle or take public transport rather than drive a car.

can be controlled if we (human) change our living lazy life. plant more trees, depends on conventional transport

Electric vehicle should be used in place of diesel and petrol vehicle to prevent air pollution

@ Anurag Saxena: Electric vehicle is good option but for the daily life (for short distances) bicycle must be given preference.as suggested by Ahsan Siddiqui.

It is good for health too.

Thanku sir V. K. Singh for the suggestion

sure

Obviously, yes. You must act in the source (reducing diesel cars, changing to renowable energy, introducing electric cars...) and in the chymenys through filters and other mechanisms. Atmospheric pollution kills 7 million people evey year.

Thanks Dr. Federico velázquez de castro for your rep[ly.

Your suggestion should be followed.

Regards

Yes, by controlling the causative causes of environmental pollution. The resulting noise is the biggest nuisance.

Thanks Dr. Shwaish for your comment.

Air pollution can be easily controlled by all human beings when they become serious an enthusiastic to put an end to the major sources of pollution. This is a huge action which can be achieved through collaborative work of individuals and governments.

Thank you Dr. Hazim Al Dilaimy for your great suggestion.

This is the responsibility of every one.

Regards

Air Pollution impair human health while breathing and people get tired easily when it is dirty. I think if there are many trees and less cars, then air quality might be improved.

Thanks Dr Gulzhaina Kassymova for raising the important issue about tree plantation.

Trees are providing oxygen, enhancing air quality, atmosphere improvement, moderating water, safeguarding soil, and supporting wild life.

Regards

Hi,

Air pollution has negative effects on the health of humans and the environment as a whole, for this reason we must put plans for protection and for air purification by installing different treatment processes at the exit of all the pollution sources what will allow to reduce the rate of pollution, on the other hand the governments must put in place a set of legislative texts in order to penalize the polluting industries. With this policy we can keep the air we breathe clean.
