Air Pollution: Science, Health Impacts, and Modern Solutions

Air pollution is one of the greatest environmental and public health challenges of our time, yet understanding its complex sources and solutions can feel overwhelming. This text-based course guides you from foundational environmental science to actionable mitigation strategies. You will build a solid understanding of how pollutants behave in the atmosphere, how they impact human health and ecosystems, and how modern technology and policy are being used to combat this global issue. What you'll learn: - Understand the primary chemical pollutants, their atmospheric interactions, and their major emission sources. - Analyze the short- and long-term impacts of poor air quality on human health, agriculture, and global ecosystems. - Evaluate modern air quality monitoring techniques, including real-time AQI tracking and low-cost IoT sensor networks. - Apply foundational principles of environmental policy, regulatory frameworks, and urban planning to reduce emissions. - Explore actionable mitigation strategies, from industrial filtration technologies to individual and community-led initiatives. The course begins with essential terminology and the basic chemistry of clean versus polluted air. From there, you will progress through health and ecological impacts, modern monitoring technologies, and practical policy and engineering solutions. This course is designed for beginners, environmental advocates, and curious learners looking to understand air quality science without any prior background in chemistry or environmental engineering.
