Question 43

Accelerated aging of the lungs, increased risk of asthma, and increased risk of cardiovascular disease are health problems associated with long-term exposure to air pollution.

Long-term exposure to air pollution is linked to serious health issues, including accelerated aging of the lungs, an increased risk of asthma, and an increased risk of cardiovascular disease. These conditions highlight the detrimental impact of polluted air on respiratory and cardiovascular health.

A) Accelerated aging of the lungs

This option is correct as research has shown that prolonged exposure to air pollution can lead to structural changes in the lungs, resulting in accelerated aging and decreased lung function over time.

B) Increased lung capacity

This option is incorrect. Long-term exposure to air pollution does not lead to increased lung capacity; rather, it can cause lung damage and reduced lung function, contradicting the idea of improvement in lung capacity.

C) Increased risk of asthma

This option is correct, as several studies indicate that air pollution is a significant contributing factor to the development and exacerbation of asthma, especially in children and individuals with pre-existing conditions.

D) Increased risk of cardiovascular disease

This option is also correct. Numerous studies have established a clear link between air pollution exposure and heightened risks of cardiovascular diseases, including heart attacks and strokes, due to inflammation and other harmful effects on the cardiovascular system.

Conclusion

The correct answer includes options A, C, and D, all of which are supported by extensive research linking air pollution to serious health complications. Option B is clearly incorrect as it contradicts the adverse effects associated with air pollution exposure. Together, these findings emphasize the critical health risks posed by long-term air pollution exposure, particularly in respiratory and cardiovascular health.
