Beijing Air Pollution Off the Charts -

北京の空気汚染がひどいとのニュース。アメリカ大使館が観測を始めた2008年以降で最高の値である755を記録した。二年まえにある大使館員がTwitterで“Crazy Bad”と表現した500という数値をはるかに上回った。指標範囲外=Beyond Indexとの表現。
301 and 500 are “Hazardous,” meaning people should avoid all outdoor activity.300を超えたら戸外での活動を避けなければならない数値だけど、恒常的に超えている状況にある。ニューヨークの値は日曜日のPM6:00で19だった。北京のダウンタウンでは数ブロック先の高層ビルが見えないほどになっている。
