    Abstract: Ozone is a molecule containing three oxygen atoms which is blue in colour and has a strong odour. Ozone is considered as helpful in the stratosphere and harmful substance in the troposphere. Most atmospheric ozone is concentrated within the stratosphere, about 15-30 km above the Earth’s surface. Chlorofluorocarbons (CFCs) are a family of chemical c... Show More
