What are facts about ozone?
Here are some interesting facts about our ozone layer. Fact 1: The ozone layer is 20 kilometers thick and is made of ozone gases. It resides in the upper atmosphere, known as the stratosphere. Fact 2: The ozone layer’s role is to filter out harmful ultraviolet radiation, which is harmful to humans and animals on Earth.
What is the ozone level?
Levels of ozone under 0.045 ppm are considered good, while a moderate level of ozone is between 0.045-0.075 ppm. For at risk groups, an ozone level over 0.075-0.105 ppm can be dangerous. A reading of over 0.105 ppm indicates an unhealthy or dangerous level of ozone.
What is ozone atmosphere?
Ozone (O3) is a highly reactive gas composed of three oxygen atoms. It is both a natural and a man-made product that occurs in the Earth’s upper atmosphere (the stratosphere) and lower atmosphere (the troposphere). Depending on where it is in the atmosphere, ozone affects life on Earth in either good or bad ways.

Is the smell of ozone dangerous?
Despite its (sometimes) pleasant and clean smell, pure ozone is remarkably dangerous and in relatively high concentrations, it can destroy cells in your lungs. Luckily, the concentration of ozone before or after a thunderstorm is highly unlikely to do you any lasting harm.
Is the ozone getting better?
The United Nations said, the ozone layer of Earth is getting better. A new report from the United Nations states that the protective ozone layer of earth is recovering from the loss caused by aerosol spray and coolant. The ozone layer had become finer since the 1970s.
What are the sources of ozone?
