Air Pollution – Causes and Effects on Human Health

We’ve all heard about pollution in school, but perhaps we don’t realize just how much air pollution harms us every day. Everyone knows that it’s a negative term, but many are not really aware of its causes and what it can do for health.

Air pollution is basically the existence of humanmade, synthetic particles that are almost unseen in the atmosphere. As we breathe, the polluted air gets into our systems and creates several imbalances and other problems.

To catch you up on air pollution, we’ve listed a few causes of air pollution below. After these, we’ll touch upon how air pollution has deteriorated our health.

Causes of Air Pollution

Below are some of the main causes of air pollution. Even a little effort in reducing these activities could result in a huge difference in the levels of pollution, especially when they’re in high concentrations:

Burning Fossil Fuels

Developed countries are the major consumers of fossil fuels like petroleum and coal. These are also non-renewable, so using them in such large amounts is irresponsible and unhealthy globally. When these fossil fuels are burnt, they emit carbon monoxide and sulfur dioxide. The main cause of such burning is cars, factories, and any other humanmade processes.

Of course, making use of fossil fuels does contribute to a lot of convenience in your life. However, such convenience’s aftereffects have a highly negative effect on your health and even your life.

Agricultural Activities

Agricultural work serves to create the most common kind of air pollutant. This is known as ammonia, a highly dangerous chemical that can get into the atmosphere and damage your health. It is widely used in insecticides, pesticides, fertilizers, and several other products used in commercial agriculture.

Ammonia oxide, which is the chemical caused by spraying all the things listed above, is also responsible for water pollution. When the runoff from the field enters the river and streams, it could contaminate the entire population’s drinking water.

Mining Activities

Another industry that makes a lot of pollutants in its everyday running is mining. This involves using dynamite, heavy machinery, and several other activities that cause air pollution. It’s not just the use of fossil fuels but also the dust and chemicals created. In fact, everyday mining operations have been known to decrease the lifespan of the workers and people living near the mining site.

Air Pollution Indoors

Air pollution is also dangerous inside your home, office, and any other building. There are all kinds of chemicals mixed in with the paint on the walls and even cleaning products. When these pollutants are breathed in within a confined space, they can do even more damage than the regular pollutants outdoors.

There is even an estimate by the Environmental Protection Agency that homes could be more than twice as polluted as the outdoors when such chemicals are used frequently. Hence, it is recommended that you use environmentally friendly products and air filters to get high-quality air inside your home and workplace. Since you spend a high amount of time there, you should also be taking care to breathe clean.

Effects on the Human Health

You may not be able to actually see the pollutants in the air you breathe every single day, but there is a reason why many doctors recommend a visit to the mountains or the sea for ailing individuals. The air in such places is usually much cleaner than what you experience in big cities and towns. If you don’t get regular access to clean air as a norm, you may face the following detrimental effects on your health:

Chemical Poisoning

When you breathe in chemicals daily, you may face a sort of poisoning. This is evidenced by the 1994 Bhopal disaster, where around 6000 people died in Bhopal (India) due to chemical poisoning. The culprit was a leakage of poisonous gas from a pesticide plant.


With a high level of pollutants in the air, the body may increasingly become more vulnerable to several forms of cancer. The Great Smog of London is another historical event related to air pollution, causing a high number of deaths. During this time, harmful pollutants from burning coal created a heavy smog over the city of London. This caused the death of no less than 4000 people. In addition to these deaths, the rates of cancer also reached an all-time high during this period.

Respiratory Issues

When the air is heavy with pollutants, it also becomes harder to breathe. This is mainly because the body is so caught up in blocking the harmful elements that it simplifies breathing difficult. When you’re coughing, sneezing, or covering your mouth all the time, taking a deep breath would be near impossible. Even if you do manage to breathe deeply, health experts wouldn’t recommend this when you’re living in an area with high air pollution.

Psychological Damage

Mental and emotional health is just as important as the physical kind. When you’re unable to breathe properly or even look at plants without black marks of smog, you naturally feel worse about life in general. Additionally, harmful pollutants have a depressing effect on one’s mood in general. With this low state of mind, it could be hard for anyone to have a positive outlook on life. They may, hence, be more vulnerable to mental disorders and other related issues.


It can be easy to forget about air pollution, especially since you can’t see it very well. However, this is all the more reason why you need to keep reminding ourselves of this problem and try to combat it as much as possible. With the right kind of plants, a large number of trees, and a whole lot of care, we may be able to clean up the air of even the biggest and busiest cities.

My name is Ryan. I have had a hard time dealing with my allergies. Happily, I found that an air purifier was effective to ease my allergy symptoms. I spent a lot of time researching the best air purifier. I know how hard it can be to find the suitable one. During the reading period, I also read a lot about humidifiers and dehumidifiers. I learned the mechanisms behind the technologies as well as the manufacturers and organizations within the industry.
