Ozone is a gas composed of three oxygen atoms, commonly found in the Earth's atmosphere. It plays a crucial role in protecting life on our planet by absorbing harmful ultraviolet (UV) radiation from the sun. This protective layer, known as the Ozone Layer, is located in the stratosphere and is vital for maintaining the health of ecosystems and human beings alike. However, ozone can also be a harmful pollutant at ground level, where it forms as a result of chemical reactions between volatile organic compounds and nitrogen oxides in the presence of sunlight. This ground-level ozone can lead to respiratory problems and other health issues, making it important to monitor and manage air quality effectively.
