Environmental health focuses on:

• A. The study of how environmental factors affect human health, including air, water, hazards
• B. The assessment of environmental laws and policies
• C. The management of hospital environmental safety
• D. The economic impact of pollution

Answer: (A)

Environmental health examines how environmental conditions influence human health. It looks at how exposure to air pollutants, drinking water contaminants, hazardous materials, and other environmental factors can lead to health problems, affect disease patterns, and determine who is at greater risk. This focus on the link between environment and health, including the pathways of exposure and resulting health outcomes, is why this option is the best fit. The other areas touch on important related topics but not the heart of environmental health: evaluating environmental laws and policies is about governance and regulation; managing hospital environmental safety is a specific operational concern within healthcare settings; examining the economic impact of pollution belongs to environmental economics and health economics.
