More than 20 million residents in Delhi’s metropolitan area are yet again facing some of the worst pollution on earth, with air quality degrading to dangerous levels this week as a mix of weather conditions, urban emissions, and rural smoke converge over India’s capital region. 德里城区内有2千多万居民，该地再次面临全球最严重污染，本周受天气状况、城市排放和笼罩在印度首都的乡村烟雾的综合影响，空气质量降至危险水平。 Delhi’s Chief Minister Arvind Kejriwal turned to Twitter to describe his city as a “gas chamber.” 德里首席部长Arvind Kejriwal在推特上说这个城市成了“毒气室”。 The gray haze led to canceled flights, closed schools, and created a public health emergency. The government distributed 5 million face masks to schoolchildren. 灰霾导致航班取消、学校放假、公众健康陷入危机。政府给小学生发放了500万个口罩。 On Monday, some air quality index monitors maxed out with ratings of 999 and pollution reached 50 times the level deemed safe by the World Health Organization. For Delhiites, breathing the air was like smoking 50 cigarettes in a day. The US Embassy in New Delhi maintains its own air quality monitor and reported Thursday that the air quality index improved to a rating of 255, merely “very unhealthy.” 周一一些空气质量指数监测器爆表，指数达到999，污染程度达到了世界卫生组织安全标准的50倍。德里市民呼吸这样的空气就好比一天吸掉50支香烟。美国驻新德里大使馆使用自己的空气质量监测器，周四报告称空气质量指数提高到了255，仅仅是“非常不健康”。 |
