Pollution and Health Effects

Scientific studies have linked long-term particle pollution, especially fine particles, with significant health problems including increased respiratory symptoms, such as irritation of the airways, coughing or difficulty breathing, decreased lung function, aggravated asthma, development of chronic respiratory disease in children, development of chronic bronchitis or chronic obstructive lung disease, irregular heartbeat, nonfatal heart attacks, premature death in people with heart or lung disease, including death from lung cancer. Ground-level ozone reaches its highest level during the afternoon and early evening hours. High levels occur most often during the summer months. It is a strong irritant that can cause constriction of the airways, forcing the respiratory system to work harder in order to provide oxygen. It can also cause other health problems.
