Ozone (O3) is the most reactive gas in the air. It plays a crucial role in the stratosphere by protecting life on Earth from the sun's harmful ultraviolet rays. However, at ground level, ozone becomes a pollutant, posing health risks and contributing to air pollution. Therefore, understanding and monitoring ozone levels is essential for environmental and public health.

FAQs & Answers

  1. Why is ozone considered the most reactive gas in the air? Ozone (O3) is highly reactive due to its strong oxidizing properties, allowing it to interact readily with other substances in the atmosphere.
  2. How does ozone protect life on Earth? Ozone in the stratosphere absorbs the sun's harmful ultraviolet (UV) rays, preventing them from reaching the Earth's surface and protecting living organisms.
  3. What health risks does ground-level ozone pose? At ground level, ozone acts as a pollutant causing respiratory problems, aggravating asthma, and contributing to other health issues.
  4. How can we monitor and reduce ozone pollution? Monitoring ozone involves air quality sensors, and reducing pollution includes limiting emissions of ozone precursors such as nitrogen oxides (NOx) and volatile organic compounds (VOCs).
