新奇事件簿 印度城市空气质量达到危险水平
Many of India's big cities are experiencing such hazardous air pollution that it almost defies belief. The standard measurement for healthy, normal, breathable air is set at a level of 50 according to the Air Quality Index (AQI). A level of 300 means the air is hazardous to breathe. The AQI website says 300 represents a health alert and the city should be put under emergency conditions. The website says that, "everyone may experience more serious health effects". On November 8, the city of Chandrapur in Maharashtra reached an AQI level of 824, to become India's most polluted city. The capital New Delhi has reached an AQI of 724. Environmentalists say many cities are now like "gas chambers".
印度许多大城市都经历了如此危险的空气污染，几乎让人难以置信。按照空气质量指数AQI，健康，正常，可呼吸的空气标准为50。300意味着呼吸这种空气是危险的。AQI网站表示，300意味着健康预警，这座城市应该进入紧急状态。这个网站表示：“每个人都可能遭遇更加严重的健康影响。”11月8日，马哈拉施特拉邦Chandrapur市AQI达到824，成为印度污染最严重的城市。首都新德里的AQI达到724。环境保护主义者表示，许多城市现在就像毒气室。
A toxic haze shrouds India's capital and residents are being warned to wear masks. Schools were ordered closed for three days. New Delhi generally has its fair share of pollution problems due to the nine million vehicles that clog its streets, most not conforming to emissions standards. The situation has been made worse recently due to a number of factors. These include chemical pollution blowing in from nearby states, farmers setting fire to straw as autumn arrives, and a lack of wind. To alleviate the crisis, city officials have ordered roads to be doused with water to stop dust from rising. They have also banned diesel-powered electricity generators for 10 days, except at hospitals and cellphone towers.
一场有毒浓雾笼罩着印度首都，政府警告居民们佩戴面具，并下令学校停课三天。由于900万车辆拥堵着街道，大多数并未遵循尾气排放标准，新德里的空气污染问题也同样严重。最近，由于几个因素的共同作用，形势更加恶化。其中包括附近邦吹过来的化学污染，秋季来临农民点火燃烧秸秆，以及风力不足。为了缓解空气污染危机，城市官员已下令街道洒水，防止尘土飞扬。他们还禁止柴油发电机停工10天，医院和手机塔除外。
