Slide 1 - National Air Quality Index (How healthy is the air we breathe?) AQI = 230; Poor Responsible Pollutant: PM10 Indian Institute of Technology Kanpur, Kanpur Sponsored by : Central Pollution Control Board, Delhi
Slide 2 - Are we affected by poor AQ? The very young are at risk Lungs are not fully developed Faster breathing rate: more air volume/body weight The very old are at risk Undiagnosed lung or heart diseases Pollution can exacerbate these conditions Persons with chronic illnesses: Respiratory, circulatory, or cardiac diseases Yes, EVERYONE! Even healthy persons can be affected when they exercise outdoors, or if the concentration of pollutants is very high
Slide 3 - How do we know if Air Quality is poor? AQI is an overall scheme that transforms individual air pollutant (e.g. SO2, CO, PM10) levels into a single number, which is a simple and lucid description of air quality for the citizens. AQI relates to health impacts and citizens can avoid the unnecessary exposure to air pollutants; AQI indicates compliance with National Air Quality Standards; AQI prompts local authorities to take quick actions to improve air quality; AQI guides policy makers to take broad decisions; and AQI encourages citizens to participate in air quality management.
Slide 4 - Pollutants Considered for AQI and Air Quality Standards
