Studies have found that air pollution may affect every organ of our body

Dementia, heart and lung diseases, fertility problems and mental decline are some of the problems caused by air pollution[4].

If you are exposed to air pollution every day, your whole body is actually damaged, not just your respiratory system.

Air pollution is the most harmful to children and unborn babies.

Studies have found that air pollution may affect every organ of our body

Air pollution is a “public health emergency” and is listed by the World Health Organization as the top ten health threats in 2019[5].

More than 90% of the world’s population can tolerate poisonous air, whether indoors or outdoors. An exhaustive scientific review confirmed that air pollution is the fifth leading cause of death in the world[6].

The author wrote: “Ultrafine particles pass through (lungs) and are easily captured by cells. They are transported through blood and exposed to almost all cells.”

Although air pollution affects people in all regions, ages and social groups, it is likely to lead to greater diseases among people with high exposure and susceptibility.

If people suffer from other diseases or lack medical conditions, they are more vulnerable to air pollution.

Dr Maria Neira, director of public and environmental health of the world health organization, told the guardian: “this provides new evidence for the large amount of evidence we have. More than 70,000 scientific articles show that air pollution is affecting our health. “

Silent killer

One of the reasons why air pollution causes great damage is that very small particles can penetrate the lungs and spread all over the body.

As far as the lungs are concerned, particulate matter entering the lungs can cause respiratory problems, ranging from asthma to emphysema to lung cancer.

There is now sufficient evidence that air pollution not only causes serious damage to the lungs but also to the heart. With the contraction of arteries and muscle atrophy, the risk of heart attack increases.

Arsenic, lead, cadmium or sulfuric acid, polycyclic aromatic hydrocarbons and other compounds can be collected in the combustion process and transported to the depths of the lungs through the surface of ultrafine particles.

This situation is more common in particles produced by fossil fuel combustion, especially coal combustion, which contains many heavy metal components and high sulfur levels.

In addition to invading organs and causing direct damage, exposure to pollutants such as toxic metals, organic compounds and gases can also cause inflammation and affect the whole body[8].

Inflammation usually occurs in the lungs, causing oxidative stress, which in turn triggers a series of events that affect distant organs. The larger the ultrafine particles, the greater the ability to generate oxidative stress.

This leads to vascular problems, such as atherosclerosis, and can have extensive effects on metabolism[7].

Ultrafine particles directly entering different organs may also cause inflammation in the organ. Basically, neither lungs nor blood can resist the presence of toxic particles.

Studies have proved that insomnia may be a consequence of toxic air, and stroke, dementia and mental decline are related to pollution.

The liver is one of the affected organs.

According to the Guardian, the study found that air pollution is related to a variety of cancers, including bladder cancer and intestinal cancer, in which the incidence of irritable bowel syndrome has also increased[1].

The Impact of Air Pollution on Children

The most worrying effects are childbirth and children.

For children, they breathe more air per unit weight (more time than adults spend outdoors), so they inhale more toxins than adults exposed to the same amount of air pollution.

Other studies show that exposure to air pollution will reduce fertility and increase abortion rate[2].

The fetus will also be affected. A recent study found that the placenta that nourishes the fetus contains pollutants.

On the other hand, air pollution is also closely related to low birth weight, which will lead to lifelong consequences[3].

“The best way to reduce exposure to air pollution is to control it from the source. In an interview with The Guardian, Schraufnagel, dean of the University of Illinois in Chicago, said.
