Pictures of Smog: Visual Examples of Air Pollution

📚 Quick Study Guide

• 💨 Definition: Smog is a type of intense air pollution. The word "smog" is a portmanteau of smoke and fog.
• ☀️ Formation: It's often caused by large amounts of coal burning in an area or by vehicle emissions.
• 🌡️ Photochemical Smog: This forms when sunlight reacts with nitrogen oxides and volatile organic compounds (VOCs) in the atmosphere.
• 🏢 Industrial Smog: Primarily from burning fossil fuels like coal. It contains sulfur dioxide, particulate matter, and smoke.
• 🏥 Health Impacts: Smog can cause respiratory problems like asthma, bronchitis, and even increase the risk of heart disease.
• 🌍 Affected Areas: Major cities with heavy traffic and industrial activity are often prone to smog.
• 🛡️ Solutions: Reducing emissions from vehicles and industries, using cleaner energy sources, and improving public transportation can help combat smog.
