Air quality is a significant environmental determinant of health. Pollutants such as particulate matter (PM2.5), nitrogen dioxide (NO2), and sulfur dioxide (SO2) can penetrate the respiratory system and lead to adverse health outcomes. Research has shown that long-term exposure to these pollutants can increase the risk of cardiovascular diseases, lung cancer, and even premature death. Ensuring good air quality is essential for reducing the burden of these diseases.
