India’s capital grapples with toxic winter air pollution
Even for a city considered one of the world’s most polluted, the Indian capital hit a new low this past week. Air so dirty you can taste and smell it; a gray haze that makes a gentle stroll a serious health hazard.
According to one advocacy group, government data shows that the smog that enveloped New Delhi was the worst in the last 17 years. The concentration of PM2.5, tiny particulate pollution that can clog lungs, averaged close to 700 micrograms per cubic meter. That’s 12 times the government norm and a whopping 70 times the WHO standards.
The Delhi winter, once a glorious time of clear - crisp days that meant holidays and weekends spent picnicking in its many public parks - is now a time of annual health woes. As millions struggle with hacking coughs and burning eyes, many schools across the city have either shut down or ended all outdoor activities. Doctors have asked people to stay indoors during the worst days.
No action taken
Yet many of the problems that turn Delhi’s air so toxic continue unabated. People still set off massive amounts of festival fireworks, piles of garbage burn all night and dust from the construction projects that dot the city is unchecked. And at the start of every winter, farmers in the states bordering the city begin burning straw from their rice paddy crop to clear the fields for planting wheat.
“Sources of pollution in Delhi and outside of Delhi have exponentially increased in the last couple of days,” said Polash Mukerjee, a research associate with the Centre for Science and Environment, a Delhi-based research and lobbying organization.
He said that wind direction is blowing toward Delhi from all directions, especially from Punjab and Haryana, “where there are large incidences of crop fires that we are detecting even today.”
Over the last two years, the government has tried a slew of measures to control air pollution, including stricter emission norms for cars and a tax on diesel-fueled trucks that enter the city. New Delhi also has attempted to limit the number of cars during the winter months, when air quality is at its worst. Twice the city imposed a two-week period in which cars were allowed on the roads only on even or odd days, depending on the vehicle’s license plate number. — AP
