Air pollution


Have you ever thought about environmental disasters that affect our lives? Well, one of our era's extreme disasters is air pollution, on account not only of its influence on climate change but also its impact on public and individual health due to the arising of the mortality rate.

Many pollutants are chief factors in causing disease for humans. Amongst them, Particulate Matter (PM), particles of variable but very small diameter, infiltrate the respiratory system through inhalation, causing respiratory and cardiovascular diseases, reproductive and central nervous system dysfunctions, and also may cause cancer.

Even though ozone in the stratosphere plays a protective role against ultraviolet irradiation, it is damaging when in high concentration at ground level, also it affects the respiratory and cardiovascular system.

Examples of these materials are substances that are presented naturally around us as nitrogen oxide, sulfur dioxide, Volatile Organic Compounds (VOCs), dioxins, and polycyclic aromatic hydrocarbons (PAHs) are all considered air pollutants that are harmful to humans. Besides, Carbon monoxide can even provoke direct poisoning when breathed in at high levels.

Pollution is also presented in solids and liquids not only gases. Pollutants harm our environment either by increasing levels above normal or by introducing harmful toxic substances.

At last but not least, individuals, organizations, governments and relevant bodies shall cooperate to stop air pollution in order to save our planet and millions of living organisms all over the world.
