Air Pollution

Air Pollution in today’s world makes it difficult for us to breathe pure, clean air. Strangely, we are now on a quest to look for a planet similar to earth despite the fact that ours is said to be the only planet where living things can live. Because of the numerous human activities carried out in the name of development since the industrial revolution of the 19th century, the earth has lost its freshness and purity of air. Over time, it started to have an adverse effect on all living creatures, resulting in countless negative health effects and numerous fatalities. And today, as global citizens, breathing clean air has nearly become our most important right, and the struggle continues.

What causes air pollution, and how does it affect people?

Air pollution is the impurity in the air caused by a concoction of dust particles and liquid pollutants, together known as aerosols, that has a negative impact on the health of living things and, more crucially, on the climate. Both natural and man made factors cause the increase in air pollution. To mention a few, these include the dangerous gases and smoke released by cars, factories, dust, volcanic ash, pollen grit, and wildfire dust particles

What induces pollution in the air?
Various artificial and natural calamities or factors give rise to pollution in the air. The factors are as discussed below-

Natural Causes

● Wildfires

In an extensive wooded area, prolonged dryness can lead to a devastating level of wildfire, producing harmful gas called carbon monoxide and smoke. When the smoke and carbon monoxide gets mixed up in the air, they promote carbon volume in the atmosphere, the major reason behind the Greenhouse Effect.

● Dust

Barren land areas with no vegetation cover are left dry due to scarcity of rainfall, and during the windy season, these areas become more prone to dust storms. Thus, when mixed up in the air, these granular particles have hazardous health effects for living beings. When dispersed into areas with native flora, granular particles can also act as a natural barrier to photosynthesis.

● Volcanic Eruption

One of the major natural factors giving rise to air pollution is the ashes and dust from volcanic activities. In the process of the volcanic outbreak, numerous harmful gases are emitted, that include chlorine, sulfur, ash materials, and sulphur dioxide. These materials are dispersed across wide distances by the wind and negatively impact plantations and life forms.

● Harmful chemical emissions from animal waste and some types of vegetation

Methane, the main contributor to air pollution, is released by animal manure, most notably that of cattle. While trees like oak, poplar, and willow emit a dangerous substance called volatile organic compounds (VOCs), especially on sunny days. Low-lying periodic fogs that are ozone-generous are generated when these harmful compounds interact with predominant man-made pollutants, notably nitrogen oxides, sulphur dioxide, and carbon compounds.

Man Made Factors

● Combustion from Fossil Fuels

Human development has been causing a disastrous level of air pollution and a prominent rise in global warming. One of the main contributors to air pollution is using petroleum-based fuels like coal, petroleum, and other industrial flammable materials. Harmful gases such as nitrogen oxides, CO2, and CO emitted from vehicles have led to a rebelling concern for living creatures and the earth as a whole.

● Dumping of waste materials

As a result of increased trash production and population growth, landfills are overflowing with debris. In the end, uncontrolled landfills release methane, which causes pollution and the Green House effect.

● Agricultural Activities

The demand for the increase of agricultural lands prompts the cutting down of forests that would otherwise have led to releasing oxygen and purifying the air. But as a result of rapid deforestation, there’s a sharp increase in carbon emission and resulting in Green House effect.

Effects of Air Pollution On Human Health

The contamination in the air can have detrimental effects on living organisms and the climate as a whole. There is no question as to why numerous international organisations and well-known individuals have urged the implementation of various measures to enhance the health of the air quality. In addition to producing a number of health problems, such as breathing difficulties, heart conditions, lung conditions, asthma, emphysema, and many more, it has also led to global warming, which has caused significant intercontinental tensions.

To discover more about the health problems brought on by air pollution, let’s delve a little further.

Extreme exposure to air pollution leads to a high level of unfavourable health effects that are discussed below.

● Asthma

Dust particulates and other pollutants in the air can trigger asthma in existing patients and a probable chance for non-patients and children. Breathing becomes challenging because they stimulate the airways, causing them to expand and constrict.

● Impairment of Lung Performance

The most affected populace by lung disease are those who reside in high traffic and industrially-rich areas. That’s the reason why individuals working in factories have a higher risk of suffering from lung diseases and other respiratory ailments.

● Lung Cancer

The second next activating factor to lung cancer after smoking and exposure to radioactive agents is the dirt, gas and contamination in the air quality. International Agency of Research on Cancer (IARC) revealed in 2013 that a substance named Group 1 carcinogen present in outdoor pollution had been a major element of lung cancer.

● Cardiovascular Diseases

Inhaling impure or contaminated air lets the impurities and toxic gas travel down to your blood vessels affecting the cardiovascular tissues by narrowing and stiffening them. Thus, increasing the chance of heart and respiratory disorders.

● Chronic Obstructive Pulmonary Disease (COPD)

COPD affects more than millions of people in the world, and the symptoms include inflammation of the lungs that blocks the flow of air and causes obstruction in breathing. The highly concerning factor of COPD is that it can’t be reversed. Your physician may recommend medication in the form of pharmaceuticals, mindful practices, therapies, and medical interventions based on the situation.

● Leukaemia

The most life-threatening illness brought on by air pollution is leukaemia, a category of blood cancer that develops due to prolonged submission to the benzene air contaminant. In this syndrome, the red blood cells (RBCs) and platelets, which are vital for the body to be functional, are pushed aside by the white blood cells (WBCs), which begin to grow indiscriminately.

● Pneumonia

Pneumonia, a condition where the air sacs either in one or both the lungs get swollen and are flooded with liquid substance or pus, can become fatal if not consulted with a doctor. It has been shown that adults over 60 years old are more frequently impacted by pneumonia because they have a weakened immune system and are more vulnerable to bacterial infection.

The primary 5 Indian cities vulnerable to air pollution are discussed below:

● Bhiwadi

With more than 2000 active factories located in Bhiwadi, it is regarded as Rajasthan’s industrial hub and the most polluted city in India. In 2022, it had the maximum Air quality Index exceeding 200. Eventually, its natives are noticing all the health consequences, more prominently respiratory problems.

● Ghaziabad

The PCB data indicates that Ghaziabad has an air quality index of 428 and is ranked as the second most polluted in the country.
