Long-term consequences of exposure to Polluted Air

As the world is gets hotter and more crowded, our engines continue to pump out dirty

emissions, and half of the world’s population has no access to clean fuels or technologies. The very air we breath is growing dangerously polluted. It is killing approximately 7 million people every year.

Air pollution is hard to escape, no matter how rich an area you live in. It’s all around us. Air

pollution consists of chemicals or particles in the air that can harm the health of every living

being. It can also damage the buildings. Pollutants in the air

It can be in the forms of gases, solid particles or liquid droplets.

Sources of air pollution

Pollution enters the earth atmosphere in many e different ways. Most aur pollution is created

by humans in the form of emission from factories and vehicles. Smoke caused by smoking

cigarettes is also considered as air pollution. Such types of mam-made pollution are called as anthropogenic source.

Air pollution is closely linked to climate change. The main origin of climate change is the

combustion of fossil fuels which is also a major contributor to air pollution. Some types of air

pollution such as smoke from wildfires or ashes from volcanoes occur naturally. These are

called natural sources.

Effects on humans

People experience of wide range of health effects from being exposed to bad air-pollution.

Microscopic pollutants in the air can slip past our body, penetrating deep into our respiratory

system and circulatory system ,damaging our lungs ,heart and ,brain. Illness such as pneumonia or bronchitis comes under the short term effects of air pollution. It includes discomfort such as irritation in the nose, throat, eyes or skin. Air pollution can also cause headache, dizzines and nausea. Bad smell from factories or garbage are referred as air pollution too.

Long term effects of air pollution can last for years or an entire lifetime . They can even lead to death. Long term health effects from the pollution include heart disease, lung cancer

and respiratory diseases such as emphysema. Air-pollution can also cause long-term damage to nerves, brain, kidneys, liver and other organs. Some scientist suspect air pollutants cause birth defects. Nearly 2.5 million people die worldwide each year from the effects of outdoor or indoor air pollution.

Young children and older adults, whose immune system tend to be weaker, are often more

sensitive to pollution. They might suffer from disease like asthma and heart diseases if exposed to bad air pollution. Duration of exposure to bad air pollution and the amount and type of pollutants present in the air are also of great emphasis.

Effects on the environment

Like people, animals and plants, entire ecosystem can suffer the upshots of air pollution. For

instance, smog is a visible type of air pollution which is found during winters and is fatal to our health. Hazy air pollution can even muffle sounds.

Air pollution particles eventually fall back to earth. Air pollution can directly contaminate the

surface of bodies of water and soil. This can kill crops or reduce their yield. It can kill young

trees and other plants.

Sulphur dioxide and nitrogen oxide particles in the air can create acid rain when they mixed

with water and oxygen in the atmosphere. This air pollutants come mostly from coal- fire

power plant and motor vehicles. When acid rain falls to the earth, It damages plants by

changing soil composition, degrading the water quantity in rivers lakes and streams, damage

crops and can cause buildings and monuments to decay.
