India's Supreme Court last month ruled that only firecrackers that emit less smoke and soot could be sold in the city, in an effort to limit pollution over the festival period.
Delhi's air quality typically worsens in winter, due to pollution from the burning of rice stubble, diesel engines, coal-fired power plants and industrial emissions.
"If Kejriwal government is so serious over effects of cracker bursting on air quality, would it announce a ban on it", he questioned. The US Embassy in the Delhi - which according to the World Health Organization is the most polluted city on Earth - said its readings touched 526.
The Aam Aadmi Party Thursday demanded initiation of contempt action against BJP leaders - MLA O P Sharma and party spokesperson Praveen Shankar Kapoor - for their remarks on the Supreme Court order allowing a two-hour window on use of green crackers.
Delhi's pollution level post-Diwali almost doubled in comparison to past year and entered the "severe-plus emergency" category (ten times permissible limit) as people burst firecrackers before and after the Supreme Court stipulated time frame of 8 pm to 10 pm.
The national capital woke up to a yet another smoggy morning on Friday with the air quality in the "severe" category. The AQI rose from 281 at 7 pm to 291 an hour later and by 10 pm, it was 296, said the Central Pollution Control Board (CPCB).
In a bid to combat the toxic smog that has engulfed the city, the Delhi government has banned the entry of trucks from Thursday 11 pm till 11 pm on Sunday.
The overall air quality index or AQI was 10 times the safe limit - AQI above 500 falls in the "severe-plus emergency" category, according to the government-run System of Air Quality and Weather Forecasting And Research.
The capital city was followed by Kolkata with recording the same AQI. A "severe plus emergency" level AQI essentially means that even healthy people may suffer from respiratory illnesses on prolonged exposure.
Violations of the Supreme Court order were reported from Mayur Vihar Extension, Lajpat Nagar, Lutyens Delhi, IP extension, Dwarka, Noida Sector 78 among other places.
