What is one of the primary effects of air pollution on human health?

Air pollution has significant negative impacts on human health, and one of the primary effects is the increased risk of respiratory diseases. Pollutants such as particulate matter, nitrogen dioxide, sulfur dioxide, and ozone can irritate the respiratory system and lead to conditions such as asthma, bronchitis, and other chronic obstructive pulmonary diseases (COPD). Long-term exposure to these pollutants can exacerbate existing health issues, lower lung function, and increase hospital admissions due to respiratory conditions. This connection is well-documented in numerous health studies that illustrate how exposure to poor air quality correlates with a rise in respiratory illness, clearly establishing the link between air pollution and adverse health effects.
