Short-term exposure to air pollution is particularly harmful to which demographic?

Short-term exposure to air pollution is particularly harmful to young children due to several key factors. Their respiratory systems are still developing, which makes them more susceptible to the adverse effects of pollutants. Children typically have higher ventilation rates relative to their body size compared to adults, leading to greater exposure to harmful contaminants present in the air. Furthermore, their smaller airways and lung capacity can exacerbate the impact of pollutants, increasing the likelihood of respiratory issues and other health problems. Young children also spend more time outdoors playing and engaging in physical activities, which can further increase their exposure to air pollution.

While other demographics such as senior citizens or individuals with pre-existing health conditions may also experience significant impacts from air pollution, the heightened vulnerability of young children during critical developmental stages makes them the most affected group in cases of short-term exposure.
