Question

Which of the following terms has been defined by WHO as "the control of all those factors in man's physical environment which exercise or may exercise a deleterious effect on his physical development, health and survival"?

• A. Environmental Sanitation
• B. Environmental Health
• C. Environmental Standard
• D. Environmental Control

Answer 1

The Correct Option is B

Step 1: Analyze the WHO definition. Step 1: The definition provided is comprehensive, covering the "control of all factors" in the "physical environment" that can harm human "development, health and survival."
Step 2: Compare the options with this definition.
Step 2:

Environmental Sanitation: This is a subset of environmental health, typically focused on safe disposal of human excreta, water supply, and solid waste. It is not as broad as the given definition.
Environmental Health: This is a broad field that comprises those aspects of human health determined by physical, chemical, biological, social, and psychosocial factors in the environment. The WHO definition given in the question is a classic definition of Environmental Health.
Environmental Standard: This refers to a specific regulation or level that is permissible for a pollutant or environmental factor, not the overall control process.
Environmental Control: This is a general term for actions taken to manage the environment, but "Environmental Health" is the specific public health term defined by the WHO in this context.
Step 3: Conclude the correct term.
Step 3: The definition accurately describes the scope and purpose of Environmental Health.
