Air Quality Index in Ahmedabad deteriorates, in the range of orange to red level

Ahmedabad: Air Quality Index in Ahmedabad, the most populous city of Gujarat and the seventh one in the whole of India, has seen deterioration in last few days and it has come in the range of 101-160 which is defined as ‘unhealthy for sensitive groups’ to ‘unhealthy’.

The stubble burning by farmers in the adjoining areas have also added to it.
And today on the occasion of Dev Diwali busting of fire-crackers will further worsen it.

Notably the system to monitor air quality has been placed at around a dozen places across the city. Among the most polluted areas in the city were Pirana and Bopal also.

“Good” AQI is 0 to 50 (Indicative colour Signal Green) when Air quality is considered satisfactory, and air pollution poses little or no risk. Moderate” AQI is 51 to 100 (Yellow). Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people. For example, people who are unusually sensitive to ozone may experience respiratory symptoms. Unhealthy for Sensitive Groups” AQI is 101 to 150 (Orange). Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air. Unhealthy” AQI is 151 to 200 (Red). Everyone may begin to experience some adverse health effects, and members of the sensitive groups may experience more serious effects.Very Unhealthy” AQI is 201 to 300 (Purple). This would trigger a health alert signifying that everyone may experience more serious health effect while “Hazardous” AQI greater than 300 (Maroon). This would trigger a health warnings of emergency conditions.
