What is good ozone or bad ozone?

What is good ozone or bad ozone?

Stratospheric ozone is “good” because it protects living things from ultraviolet radiation from the sun. Ground-level ozone, the topic of this website, is “bad” because it can trigger a variety of health problems, particularly for children, the elderly, and people of all ages who have lung diseases such as asthma.

What is the difference between good ozone and?

“Bad” ozone is found in the troposphere, the layer nearest the ground. Tropospheric ozone is a harmful pollutant which forms when sunlight alters various chemicals emitted by humans. “Good” ozone forms in the stratosphere, the next higher layer where some jet planes fly.

Where is the good ozone is found and why is it good?

In the stratosphere, which extends from about 10 to 50 km above the Earth’s surface, ozone is ‘good’ as it protects life on Earth from the sun’s ultraviolet rays. This is why the world is trying to stop the manufacture and use of substances that damage the stratospheric ozone layer.

Why is good ozone so important?

Good ozone. Stratospheric ozone is considered good for humans and other life forms because it absorbs ultra- violet (UV)-B radiation from the Sun (see Figure Q3-1). If not absorbed, UV-B would reach Earth’s surface in amounts that are harmful to a variety of life forms.

How does ozone affect human health?

Human Health Effects Breathing ground-level ozone can trigger a variety of health problems including chest pain, coughing, throat irritation, and congestion. It can worsen bronchitis, emphysema, and asthma. Ozone also can reduce lung function and inflame the lining of the lungs.

How does ozone damage your lungs?

When inhaled, ozone can damage the lungs. Relatively low amounts of ozone can cause chest pain, coughing, shortness of breath and lung irritation. Animal studies suggest that long term exposure to ozone may lead to permanent scarring of lung tissue, loss of lung function and reduced lung elasticity.
