Case Study 1
In densely populated urban centers, high Air Quality Index (AQI) levels have profound impacts on respiratory health. For instance, in New Delhi, India, AQI levels often reach “Hazardous” categories due to vehicle emissions, industrial pollutants, and seasonal factors like crop burning. Long-term exposure to high AQI levels directly affects vulnerable groups like children, the elderly, and those with pre-existing conditions such as asthma or chronic obstructive pulmonary disease (COPD).
Studies show that during periods of high AQI, hospitals in New Delhi report a surge in respiratory issues, with emergency visits for asthma attacks, respiratory infections, and bronchitis doubling compared to days with moderate AQI. Children exposed to high AQI experience reduced lung growth, while the elderly face higher risks of cardiovascular complications. Given the scale of impact, continuous AQI monitoring is essential in urban areas to help citizens and authorities take preventive actions. Health advisories, temporary bans on specific industrial activities, and restrictions on vehicle use are frequently implemented based on AQI data, helping mitigate immediate health risks. Thus, AQI monitoring serves as an indispensable tool for protecting public health in pollution-prone cities.
