Look beyond stop-gap steps to fight bad air
Hindustan TimesDelhi’s air quality took a sudden dip again on Sunday, with the Capital recording an air quality index of 407 at 4 pm, according to the Central Pollution Control Board. The twin factors reduced nature’s ventilation ability, trapping the local pollutants, such as motor vehicle emissions, wood-burning fires, exhaust from diesel generators and dust from construction sites. It was also more evidence of the fact that Delhi’s air is always bad and needs minor nudges from the weather or extraneous factors to become worse. On Sunday, the Commission for Air Quality Management did not invoke stringent measures under the Graded Response Action Plan Stage-III as it said Sunday’s conditions were an “aberration” and that forecasts have shown that air quality is likely to improve again from Monday since light showers are expected.
