ニューヨーク・タイムズさんのインスタグラム写真 - (ニューヨーク・タイムズInstagram)「Millions of people across North America on Wednesday faced another day of hazy skies and serious air pollution caused by smoke that had drifted down from Canadian wildfires a day earlier. Hundreds of wildfires have been burning in eastern Canada for weeks. On Tuesday, eye-watering smoke from the fires drifted south and cast a pall over parts of the U.S. Northeast and Midwest. The grayish haze had hints of orange, yellow or purple, depending on where you stood. One New York City commuter described the smell as progressing during the day from “burnt toast” to “campfire.” In Manhattan on Tuesday night, the Air Quality Index hit 218, indicating that it was very unhealthy and was likely to produce widespread effects among healthy people and serious ones for those with respiratory conditions, according to federal guidelines. Such a reading is typical in a smoggy, traffic-choked megacity like Jakarta or New Delhi but rare in New York City, where decades of state and federal laws have helped to reduce emissions. The city’s air quality was expected to deteriorate during the day on Wednesday, Mayor Eric Adams said late Tuesday, adding that schools would remain open but would not hold outdoor activities. The city and much of New York State were under an air quality health advisory alert — indicating that the index was expected to surpass 100 — that was in effect until Wednesday night.
