How bad at what level?
Air pollution levels are usually measured as Air Quality Index or AQI. According to foreign standards, an AQI of more than 200 is considered to be in the 'very poor' category and a level of 300 indicates a 'seriously poor situation'. At the same time, if the AQI level is between 0-50 then it is considered good, if it is 51-100 then it is moderate and if it is between 101-150 then it is considered 'bad air' for sensitive groups. Whereas, if AQI is found between 151 to 200 then it is 'dangerous'. Apart from this, if it is found up to 201-300 level then it is considered 'very dangerous' and if it is found more than 301 then it is considered 'very-very dangerous'.
