Who is most at risk from air pollution?

Who is most at risk from air pollution?

• A. Children
• B. Elderly
• C. Adults
• D. Young and old

Answer: (D)

Vulnerability to air pollution is highest when the body is either still developing or has reduced ability to cope with stress from pollutants. Children fit this first group because their lungs are still developing, they breathe more air per kilogram of body weight, and they’re often outdoors during peak pollution times, making them more prone to respiratory problems like asthma and infections. The elderly fit the second group because aging often brings preexisting heart and lung conditions and diminished physiological reserve, so pollution can trigger serious events such as heart attacks, strokes, or pneumonia. Because both groups are more at risk, the broad category that includes young and old best identifies who is most affected. Adults generally have fewer inherent vulnerabilities to pollution compared to these groups.
