Lahore’s air quality remained ‘hazardous’ with an air quality ranking of 447, according to Air Visual’s Air Quality Index (AQI) list on Wednesday.
The Punjab capital is ranked the second most polluted city in the world, according to Air Visual, which records air pollution levels across the globe in real time. Delhi holds the top spot, with an AQI of 556 recorded on Wednesday.
An AQI ranking between 301-500 (or above) is classified as ‘hazardous’ and would “trigger a health warning of emergency conditions. The entire population is more likely to be affected”, according to Air Now.
Government officials blame the smog on crop burnings in India. Experts, however, say that the situation is caused by pollution in the country.
