Which health effects are most closely associated with air pollution?

Respiratory problems are most closely associated with air pollution due to the harmful particles and gases present in polluted air. Common pollutants, such as particulate matter, ozone, nitrogen dioxide, and sulfur dioxide, can irritate the airways, leading to conditions like asthma, chronic obstructive pulmonary disease (COPD), and bronchitis. Exposure to these pollutants can exacerbate existing respiratory conditions, reduce lung function, and increase the incidence of respiratory infections. Additionally, long-term exposure to poor air quality can lead to serious health issues, including decreased lung health and heightened susceptibility to respiratory diseases.

While skin irritations, heart problems, and eye problems can also be associated with air pollution, respiratory problems are particularly impacted due to the direct route of inhalation, making the lungs the primary site of concern for health effects arising from air contaminants.
