What is a critical health risk associated with poor ambient air quality?

Heart disease is a critical health risk associated with poor ambient air quality due to the impact of air pollution on cardiovascular health. Exposure to pollutants such as particulate matter, nitrogen dioxide, and ozone can lead to inflammation, oxidative stress, and changes in blood pressure, which are all risk factors for heart disease. Research has consistently shown that long-term exposure to poor air quality is linked to an increased incidence of heart attacks, strokes, and other cardiovascular conditions. Poor air quality can exacerbate pre-existing heart conditions and contribute to the development of new health issues, underscoring the importance of clean air for overall cardiovascular health. Understanding this connection highlights the necessity of addressing air quality issues to improve public health outcomes.
