Air pollution,Facts, causes, Impacts & Solutions

Air pollution

  What is Air Pollution?

"Air pollution" is the presence of unwanted gases, dust particles, etc. in the air, which can harm both people and nature. It occurs regularly in urban communities, air pollution is a mixture of harmful solids, liquid droplets, and toxic gases carbon oxide, nitrogen and sulfur gases, inorganic substances, inorganic and organic acids, bacteria, viruses, insecticides, etc. Is dangerous

Air Pollution At present, due to industrialization especially in the world, the biggest problem in big cities is air pollution, one of the major environmental problems that need to be addressed with the attention of collective efforts of everyone, every day. This kind of polluted air causes health problems, illness, and death.



Causes of Air Pollution

There are a huge number of different contributors to air pollution including a range of chemicals from a wide range of sources.

All pollutants have either a natural or human source.  Modern living has resulted in a shift towards human activity being the main contributor to poor air quality and pollution.


The 
natural causes of air pollution may include factors that are out of control such as volcanic eruptions, forest fires caused by elevated temperatures and natural radioactivity emitted by soil and rocks. The pattern of this type of pollution is usually quite isolated, very limited in impact and overall contributes little to the 'big picture'.

Human activity, on the other hand, is by far the biggest threat to health through contamination of the air we breathe. The two big polluting activities include the continued use of fossil fuels to generate our electricity and the burning of these fuels in our cars. Conservative estimates suggest these two activities contribute up to 90% of the air pollution in any industrialized country.


Some cities suffer more than others, simply because of the concentration of polluting industries in a small geographic area.



The Impacts of Air Pollution

Air pollution is a serious cause for concern in that if impacts the lives of countless individuals around the world.

Different substances in the air will affect the health of people based on the chemicals that they are exposed to, the concentration and length of exposure. If you live in a city constantly exposed to high levels of detrimental chemicals in the air, your long-term health will suffer.


There are varying estimates on the number of deaths directly attributed to air pollution, but it's clear that those with heart and lung disorders, alongside young children, are most vulnerable.


The cocktail of chemicals found in air pollution often works in combination with each other to impact health. It's very difficult to attribute specific health conditions to specific chemicals in the air. However medical science has established that the effects of poor air quality can be accumulative, and prolonged exposure throughout life can result in long-term health consequences.


An additional impact that should also be considered is the effect on sensitive ecosystems. Trees and plants can become prone to disease. Fish and other animals will often find polluted rivers become totally inhabitable, as pollutants from the air dissolve in surrounding areas of water



  Air Pollution Facts

Here are some basic facts about worldwide Air Pollution,  and reasons why we should all start to makes changes in our daily lives that begin to impact the quality of air that we breathe:

Every single day the average individuals inhale 20,000 liters of air. If there are dangerous chemicals in that air, then we take into our bodies with every breathes.

Air pollution is present both indoors and outdoors. Polluting compounds can often be trapped inside buildings

There are both natural (eg. volcano's) and human-based (just about everything else) sources of air pollution. Not surprisingly the human-based contribution continues to grow over time and is now by far the biggest contributor

The impact of poor air quality are wide-ranging and impact the health of human beings whilst de-stabilizing sensitive ecosystems

By its nature air pollution resides in the atmosphere, and therefore travels very easily; making this a global problem

Densely populated cities with a large number of pollutants such as cars suffer the greatest from poor air quality.

Air Pollution Solutions That Work

Contributing to air pollution solutions is a global problem, that requires a coordinated and focussed intervention at governmental and policy level. Scientists and experts in the environment have come up with a number of key actions that should be rapidly progressed, in order to bring this global problem under control.

There are broadly two approaches to the problem:

Preventative - which is all about controlling and preventing the release of air pollutants into the atmosphere
Cure - which is all about cleaning up the area that is impacted and damaged by air pollution
Both approaches work hand in hand and given we're not working from a blank sheet or a 'clean' starting position different approaches are required depending on the extent of the problem.

In the preventative camp, there are about 5 well-established approaches being adopted by governments worldwide.

These include

Restrictions on population growth
A conscious effort by the populous to conserve and waste less energy
The reduction of the amount of 'waste' produced, combined with a focus on recycling
Improve the efficiency with which energy is produced
A drive towards the production of non-polluting renewable energy sources
Controls that seek to address and 'clean-up' polluted air are generally much less effective and both difficult and expensive to implement.  The old adage of 'prevention being better than cure' absolutely applies to the big problem of how to implement air pollution solutions.

Air Pollution Solutions Towards A Better World

The world is currently surrounded by many environmental issues and one of them is air pollution. With this worldwide essay comes numerous air pollution solutions. In fact, the number of possible solutions is the same as the types of air pollution that are endangering the planet. This is because the market does not have one product that can solve the pollution in the air around us.

China, known for its economic growth together with its use of industrial equipment, is responsible for the country's current situation of air pollution. This great nation uses 6% of its electricity in running constructions that are making cement. In effect, these kilns emit enormous amounts of sulfur dioxide, carbon monoxide, mercury, and other harmful substances. Clearly, these cement-making plants do not have a certain kind of technology that helps reduce emissions.

In Australia, most of the major industries there are seriously considering to go green as their way to help save the environment. While in another continent, Africa is strengthening its South African legislation to regulate smoking in public places, manufacturing, and marketing of cigarette products to help the reduction of the death toll caused by tobacco smoke.

These are just some of the countries that are implementing air pollution solutions in order to stay healthy, despite the hazard of polluted air brings. Most people cannot let go of the comfort and convenience of cars and other vehicles, even though they are causing greenhouse effects. However, you can help save the planet in your own little ways such as cleaning the air filters as well as practice better driving that saves more on fuel. You can also open the car windows rather than using the air conditioner.  Furthermore, why not resort to walking instead of driving when you go to locations with short distances.

You never know, you are saving yourself from having serious diseases such as asthma by doing those air pollution solutions. Food, animals, cold air, air pollution, etc. can easily trigger an asthma attack. An attack that affects millions of people all over the world.

Since there is no stopping these pollutants in the air, the best way to protect yourself is to find the best air pollution solutions. However, it is essential to determine the different types of pollutants that contaminate the air. These include :

- The odor that comes from humans, animals, cigarettes, clothing, and the likes. Well, they are definitely not deadly, but still, add to the pollution in the air.

- Microbial which are composed of fungi and bacteria from mold spores, mildew, and viruses. And because they are microscopic, they might as well live comfortably in the walls, in the air-conditioning ducts, or under the carpet for several months and even years.

- Chemical fumes from formaldehyde and benzene which seep from furniture, beauty products, or cleaning products. Most of these chemicals are classified as carcinogens.

- Particulates, which are the things that float through your window when the sun shines through. These are dust mites, dust, pollen, allergens, or smoke particles.

- Radon, which is considered the heaviest gas is known on the planet. It is all around us, which is why it is the second well-known cause of lung cancer.

Air pollution solutions are easy to carry out once you have identified the cause of these contaminants. Do your part in making Earth a healthy place to live in.
 Solutions for air pollution in the home
 Air pollutants can have a serious impact on you and your families health. Recent tests in the US by the Environmental Protection Agency have concluded that the air outside can generally be between two and five times less polluted than the air in your homes. If you think of the proportion of time you spend indoors, in relation to outdoors, you can immediately see that this is a serious problem that cannot afford to be ignored.

If we look in broad terms, then there are many things we can do to mitigate against the main factors that lead to poor indoor air quality. There are three simple things that we can look at to help solve the issues i) ensuring that windows are often opened and therefore air is circulated ii) fundamentally changing the way we live and iii) making use of air purification devices.

The listings below look at some of the most common causes of air pollution in homes:-

Environmental Tobacco smoke (ETS)
Those most heavily exposed to smoke, are obviously most at risk. The associated health risks are well documented eg. Cancer, asthma, lung ailments, etc, but smoking can also be especially dangerous for young babies, as several studies have linked smoking to cot deaths. The simple solution is to ensure that your house is smoke-free if you do have smokers in your house then ensure that they smoke outside. If you feel that this is not feasible then a lesser solution would be to purchase an air purifier.

Allergens-Within your home, many different types of allergens exist. These range from pet dander, to pollen, to dust mite excrement and mold/ mildew. These can cause and exacerbate respiratory illness. There are different ways to tackle these issues although in general, the approach is to minimize as opposed to eradicating.

Pet dander - certain hoovers are specifically designed to remove pet hairs.

Mites – once again specific hoovers bags/filters can be bought to reduce levels in the home. Hoover mattresses and pillows regularly.

Pollen – air ionisers can help remove pollens.

Mold/mildew- humid, damp houses are generally the cause of these issues. You’ll need to remove the mold (a solution of bleach and water will help). After the area has been treated there are numerous solutions to help. The easiest of which are i) ensure windows are opened daily, ii) purchase an air dehumidifier to remove excess moisture from the air.

Carbon Monoxide

This is a colorless, odorless, tasteless gas that is lethal in large doses. Due to the nature of the gas, it is very difficult to know if you have a problem. Dangerous levels of Carbon Monoxide in the home are generally caused by faulty gas appliances. You should ensure that registered gas engineers install and service equipment of this nature (boilers, fires, etc). Cheap Carbon Monoxide detectors are easily available and will change color if there is a problem.


Respirable Particles

Within the home, these types of particles are mostly what is commonly known as ‘dust’. However, also tobacco smoke, wood fireplaces/stoves, and kerosene heaters can also contribute. These particles can lead to irritation of the eyes, nose, and throat, and can, therefore, lead to ailments such as bronchitis. In order to counteract these issues, homes should be well ventilated and you can also purchase air purifiers to remove particles from the air.

Radon

Radon is a natural radioactive gas which is naturally present in all rocks and soils. It is colorless, tasteless and odorless and produces no immediate symptoms. Levels of Radon gas depends on the geological conditions and can, therefore, vary depending on your geographical location. Testing kits are available to determine the levels in your home and the most effective solution to high radon levels is to fit a Radon sump. This enables the Radon to vent into the atmosphere as opposed to into your home
