📚 Quick Study Guide

    🔍 Smog is a type of air pollution formed from a mixture of pollutants, primarily ground-level ozone and particulate matter. ☀️ Photochemical smog requires sunlight to initiate the reactions. 🚗 Primary pollutants, such as nitrogen oxides ($NO_x$) and volatile organic compounds (VOCs), are emitted directly from sources like vehicles and industrial facilities. 🌡️ Temperature inversions trap pollutants near the ground, exacerbating smog formation. 🌳 Vegetation can release VOCs, contributing to smog formation in some areas. This is more significant in rural settings. 🌬️ Wind patterns influence the dispersion of pollutants; stagnant air masses promote smog buildup. 📝 Reducing smog involves controlling emissions of $NO_x$ and VOCs through regulations and technological advancements (e.g., catalytic converters).
