The Impact of Air Pollution on Public Health

What is Air Pollution?

Air pollution means harmful substances in the air we breathe. These substances can come from cars, factories, or even wildfires. Because air pollution is often invisible, many people do not notice it. However, it can still harm your health. The impact of air pollution on public health is a growing concern worldwide. In cities, air quality can be much worse than in rural areas. Yet, even small towns can face air pollution problems.

How Air Pollution Affects Public Health

Air pollution can harm almost every part of your body. For example, it can make it hard to breathe or cause coughing. Over time, it may lead to serious health problems. According to the World Health Organization (WHO), air pollution causes millions of deaths each year. Children, older adults, and people with health problems are at higher risk. Still, everyone can be affected by poor air quality and health issues.

Common Symptoms and Health Risks

Many people notice symptoms when air pollution levels are high. These symptoms can be mild or severe. Some common air pollution symptoms include:

Coughing or throat irritation

Shortness of breath

Watery or itchy eyes

Wheezing or chest tightness

Headaches or dizziness

But air pollution can also cause long-term health effects. For instance, it can increase the risk of:

Asthma attacks

Heart disease

Lung cancer

Stroke

Chronic lung diseases

In addition, children may develop breathing problems or allergies. Pregnant women exposed to air pollution may face risks for their babies.

Causes and Major Sources of Air Pollution

There are many sources of air pollution. Some are natural, but most are caused by people. The main causes include:

Vehicle exhaust from cars, trucks, and buses

Factories and power plants burning coal or oil

Burning wood, trash, or crop waste

Wildfires and dust storms

Use of certain chemicals in homes and farms

Urban areas often have more air pollution due to heavy traffic and industry. However, rural areas can also be affected, especially during crop burning or dust storms.

Diagnosis and Monitoring of Air Pollution-Related Illnesses

Doctors may ask about your symptoms and where you live or work. They may check your lungs and heart. Sometimes, they use breathing tests or chest X-rays. Air quality monitors in your area can show if pollution levels are high. You can also check daily air quality reports online or on your phone. If you notice air pollution symptoms, it is important to seek medical advice.
