(3) What are the health problems caused by air pollution?
Answers
Answer:
Air pollution can affect lung development and is implicated in the development of emphysema, asthma, and other respiratory diseases, such as chronic obstructive pulmonary disease (COPD). PM and nitrogen oxide are linked to chronic bronchitis.
The effects of air pollution vary from person to person. A healthy adult who is exposed to these pollutants for a short time or at low dose may not have long-term problems. But it's different for people with a heart or respiratory condition. For these people, even a small dose or a short exposure can make symptoms worse. Longer exposure or a higher dose can lead to serious illness. In some cases, it can lead to death. Children and older adults are more likely to be affected by air pollution than others. They can suffer the effects at lower pollution levels.
