Air Pollution Talk

Ozone is a gas that is naturally found in earth’s upper atmosphere, where it forms the ozone layer. The ozone layer blocks some of the sun’s harmful ultraviolet (UV) rays.

While Ozone layer protects us from getting all the UV rays, ground-level ozone is a pollutant that can harm the environment, crops, and human health. It is ozone in the lower atmosphere, close to the Earth’s surface. This is one of the main components of smog. Ground-level ozone is formed when sunlight and heat cause chemical reactions between nitrogen oxides and volatile organic compounds .

Volatile organic compounds are pollutants released by motor vehicles, factories and power plants, and chemicals such as paints and cleaners. Since we live in a modern world and we are exposed to all these wherever we go.

If you wonder what kind of health effects of outdoor air pollution can have on your health, first of all, it can cause your eyes and nose to burn, your throat to itch, and even breathing problems.

In extreme cases, exposure to air pollutants at high levels over a long period of time may lead to cancer, birth defects, brain and nerve damage. It can cause long-term injury to the lungs and breathing passages.

Air pollution doesn’t just affect women, children, and elderly, it affects everyone. Children are especially susceptible to the effects of air pollution because their lungs are developing. Outdoor air pollution also adds more harms to people who have lung and heart diseases because they are more sensitive.

In the U.S., ground-level ozone and particle pollution are two of the most common pollutants and threat to people’s health.

Ground-level ozone is ozone in the lower atmosphere, close to the Earth’s surface. This is one of the main components of smog. Ground-level ozone is formed when sunlight and heat cause chemical reactions between nitrogen oxides and volatile organic compounds (VOCs). VOCs are pollutants released by motor vehicles, factories and power plants, and chemicals such as paints and cleaners. Ground-level ozone is a pollutant that can harm the environment, crops, and human health.
