A boy lights a firecracker during Diwali celebrations, at Sector 27, in Noida. The actions come nearly at the end of a week that began with a toxic haze caused by illegal use of firecrackers on Diwali on October 27, made worse still by weather conditions that trapped them in the atmosphere and by smoke that drifted in from farm fires in Punjab and Haryana.

A view of the Central Park engulfed in heavy smog right after the night of Diwali celebrations, at Connaught Place. The Epca also ordered a complete ban on construction work, firecracker use, and activities of polluting industries such as stone-crushers. The order came amid growing criticism of the response mechanism — the Graded Response Action Plan (Grap) — and a rule that says escalating curbs will apply only when pollution has been severe for more than 48 hours.

A view of the Jama Masjid covered in dense smog. Delhi, meteorologists explained, is at present trapped in a cycle of pollution that blocks out the sun, which in turn makes the day temperatures cooler — a crucial factor that again leads to pollutants being trapped in the air. Once winds help clear some pollutants, more sunshine will aid in warming and, thus, clearing away more particles. (Sanchit Khanna / HT Photo)
