Medical Geology and Geochemistry: Earth's Impact on Health

Our physical environment directly shapes our well-being, yet the profound connection between the Earth's crust and living organisms is often overlooked. This course introduces you to the fascinating field of medical geology and geochemistry, exploring how natural geological materials and processes impact human, animal, and plant health. Through clear, written explanations, you will learn to trace the pathways of essential and toxic elements from rocks and soil into food systems and human bodies, empowering you to analyze environmental health risks. What you'll learn: Understand the foundational principles of medical geology, geochemistry, and environmental toxicology; Identify how essential trace elements and heavy metals move through the rock-soil-water-plant pathway; Analyze the biological impacts of natural geological hazards, including arsenic-contaminated groundwater and volcanic dust; Explore modern isotopic tracing techniques used to detect the sources of environmental pollution; Evaluate the relationship between local geology and regional health anomalies. The course begins with core definitions of geochemistry and elemental cycles, establishing a solid theoretical foundation. You will then progress through real-world case studies, exploring both toxic elements and essential nutrient deficiencies in soils, followed by written review exercises to consolidate your learning. This text-based course is designed for beginners, environmental science enthusiasts, and public health students, requiring no prior background in geology or chemistry.
