Kolkata's Air Worse Than Delhi
Kolkata's air pollution was worse than Delhi's for a week.
Experts say the city needs more machines to check the air quality in crowded places.
The air was very bad, especially on December 11, when the pollution levels were very high.
This can cause health problems like breathing difficulties.
The West Bengal Science Forum asked the government to take steps to reduce pollution and protect people's health, especially those who work outside and children.
Kolkata's air pollution levels exceeded Delhi's from December 6 to December 11.
Experts recommend setting up 20 automatic air quality monitoring stations in crowded areas.
On December 11, Kolkata's AQI reached a hazardous 439, while Delhi's highest was 345.
PM10 and PM2.5 levels in Kolkata were significantly above permissible limits.
The West Bengal Science Forum demanded immediate action to curb pollution and protect public health.
