Switzerland-based air quality monitoring technology company IQ Air publishes this list of cities with polluted air. An AQI score based on daily air quality gives people information about how clean or polluted the air in a particular city is, and whether or not they may be at any health risk.
According to the data, an AQI score of zero to 50 is considered good. 51 to 100 is considered moderate. And for sensitive groups, a score of 101 to 150 is considered unhealthy. 151 to 200 is considered unhealthy.
Similarly, an AQI score between 201 and 300 is considered ‘very unhealthy’ and a score between 301 and 400 is considered ‘risky’. Air pollution poses serious health risks. It is harmful to people of all ages. However, air pollution is very harmful for children, sick people, elderly and pregnant women.
