As wind drops and stubble smoulders, smog returns to Delhi
India's capital saw a deterioration in its air quality as crop burning in fields led to smoke billowing across the region. The city was covered in smog, which reduced visibility.
Deadly air amid pandemic
The Air Quality Index (AQI) increased to cross 300, which indicated "very poor" conditions. This air can lead to respiratory problems as well. In a bulletin, the country's environment monitoring agency said the wind speed did not pick as it was supposed to. And because of low wind speed, deadly pollutants often hang in the air that can cause deadly diseases.
The quality of the air is expected to be poor for at least a few days because of the crop burning.
Every winter in Delhi begins with a thick smog all over usually due to stubble burning, mixed with factory emissions and exhaust from cars. This year Delhi's average AQI was 36% higher than this time last year.
Till September, the capital and its surrounding cities had a break from the pollution, because of the nationwide lockdown that was imposed due to coronavirus pandemic.
