Input: The air quality index of the U.S. Embassy in New Delhi stood at "hazardous" levels of 497 as of 0630 GMT, with levels of airborne PM 2.5 - particles that can reach deep into the lungs - touching nearly 700 in parts of the city. That is more than 10 times the recommended safe limit of 60 for PM 2.5. A dip in wind speed and temperature is making air denser, trapping pollutants and worsening air quality, said Vivek Chattopadhyay, a senior programme manager at New Delhi-based non-profit Centre for Science and Environment. The city government of Delhi, a metropolis of over 20 million, is restricting the use of private cars until Nov. 15 with an "odd-even" system - allowing cars on alternate days, depending on whether their licence plate ends in an odd or even number. The scheme, which includes a two-day waiver for a religious festival, has helped little, prompting environmentalists to call for urgent action. "The chief minister (of Delhi) needs to declare an emergency," said Bharati Chaturvedi, founder of the Chintan environmental advocacy group. "If this was the plague, he would have declared an emergency." Every year, as India's winter season approaches, farmers in Delhi's neighboring Punjab and Haryana states, where agriculture is a mainstay, burn off rice field stubble in preparation for the sowing season. The smoke from fields mixes with vehicle exhaust and construction dust, making Delhi the world's most-polluted capital. India's Supreme Court last week chided authorities for their failure to curb the pollution and asked the city government, its neighboring states and the federal government to work together to help improve air quality.
Output:
Haze wraps India's capital again as air quality plummets.
