Air quality remains ‘poor’ to ‘very poor’ in city; stubble burning in Punjab blamed
Pollution woes continue unabated in the city. The Chandigarh Pollution Control Committee (CPCC) today released the figures of pollution in the city on November 9. The 24-hour average air quality index (AQI) was recorded at 303 in Sector 39, which falls under the category ‘very poor’, and 227 at Kaimbwala village and 253 in Sector 17, which fall under the category ‘poor’. There are six categories under which the quality of air is categorised. These are good, satisfactory, moderately polluted, poor, very poor, and severe. The AQI between 301 and 400 is classified as ‘very poor’ and causes respiratory illness to people on prolonged exposure. The figure between 201 and 300 falls under ‘poor’ category, which causes breathing discomfort to people upon prolonged exposure. The CPCC has attributed the pollution to stubble burning in the neighbouring Punjab. At Sector 39, the PM 10 (RSPM) was 211 microgram per cubic metre (µg/m3), which was more than the double of permissible limit of 100 (µg/m3). The PM 2.5 was 124 (µg/m3) whereas the permissible value is 60. At Kaimbwala, the PM 10 was 158 (µg/m3) while the PM 2.5 was 98 (µg/m3).
