Abstract

Environmental health is a critical field that examines the interactions between human health and the environment. It encompasses various disciplines, including epidemiology, toxicology, and environmental science, to understand how environmental factors influence health outcomes. "Essentials of Environmental Health" provides a comprehensive overview of key concepts, including the principles of environmental health, major environmental hazards, and the impact of environmental policies on public health. The article explores essential topics such as air and water quality, waste management, chemical exposure, climate change, and their implications for health. By integrating scientific research, case studies, and real-world applications, this article highlights the importance of a healthy environment for achieving optimal public health outcomes. The role of community engagement and advocacy in addressing environmental health issues is also emphasized. Through a thorough examination of the challenges and opportunities in environmental health, this article serves as a valuable resource for students, practitioners, and policymakers seeking to understand and improve the connections between the environment and health.
