Centre of air pollution control by WHO –
**Core Concept**
The World Health Organization (WHO) plays a crucial role in setting standards and guidelines for environmental health, including **air pollution control**. Air pollution is a significant risk factor for various respiratory and cardiovascular diseases. The WHO has established air quality guidelines to reduce the adverse health effects of air pollution.
**Why the Correct Answer is Right**
Although the specific correct answer choice is not provided, the WHO indeed has a department or collaborating centre focused on **environmental health** and **air pollution**. This centre would be responsible for setting guidelines, monitoring air quality, and conducting research to mitigate the health impacts of air pollution. The correct answer would be related to the WHO's structure or a specific collaborating centre.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific text, it's impossible to directly address why each option is incorrect, but generally, incorrect options might refer to organizations or centres not primarily focused on air pollution control by the WHO.
**Option B:** Similarly, this might be an organization or centre that, while related to health, does not specifically focus on air pollution.
**Option C:** This could potentially be a centre or organization involved in a different aspect of environmental health or a completely unrelated field.
**Option D:** This might be a national or regional body rather than a global WHO centre for air pollution control.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that **air quality guidelines** set by health organizations like the WHO are crucial for **public health policy** and for clinicians to understand the environmental factors influencing their patients' health.
**Correct Answer:** Correct Answer: D. Centre of air pollution control by WHO is not explicitly provided, thus this line is a placeholder.
