Which layer of the ozone is bad?

troposphere
“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.

What is bad ozone?

Breathing ozone can trigger a variety of health problems including chest pain, coughing, throat irritation and congestion. It can worsen bronchitis, emphysema and asthma. “Bad” ozone also can reduce lung function and inflame the linings of the lungs. Repeated exposure may permanently scar lung tissue.

What is the percentage of bad ozone in the troposphere?

In the troposphere near the Earth’s surface, the natural concentration of ozone is about 10 parts per billion (0.000001 percent). According to the Environmental Protection Agency, exposure to ozone levels of greater than 70 parts per billion for 8 hours or longer is unhealthy.

How is ozone lost in the troposphere?

Ozone is destroyed when it reacts with molecules containing nitrogen, hydrogen, chlorine, or bromine. Some of the molecules that destroy ozone occur naturally, but people have created others. The total mass of ozone in the atmosphere is about 3 billion metric tons. Ozone only screens about half of the UV-a radiation.

Where is the bad ozone located?

Ozone occurs in two layers of the atmosphere. The layer closest to the Earth’s surface is the troposphere. Here, ground- level or “bad” ozone is an air pollutant that is harmful to breathe and it damages crops, trees and other vegetation.

Why is bad ozone bad?

Breathing ozone can trigger a variety of health problems including chest pain, coughing, throat irritation, and congestion. It can worsen bronchitis, emphysema, and asthma. “Bad” ozone also can reduce lung function and inflame the linings of the lungs. Repeated exposure may permanently scar lung tissue.

Where is bad ozone found?

Is the ozone in the troposphere bad for us?

Ozone and other air pollutants are common in urban areas in late afternoon. But in the troposphere, near ground-level, ozone molecules are both air pollutants, threatening the health of living things, and greenhouse gases, trapping heat and contributing to climate change.

Does ozone permanently damage lungs?

When inhaled, ozone can damage the lungs. 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. It may also worsen chronic respiratory diseases such as asthma and COPD.
