A group of Edinburgh medical students dugup the facts on the Great London Smog of 1952 (the photos are fascinating; areal shock for people who think environmental problems are something new). Thestudents provided numbers on the level of air pollution in London 1952 and Ihave compared these to recent numbers for Beijing.
幾位愛丁堡大學(xué)醫(yī)學(xué)院的學(xué)生發(fā)掘了1952年倫敦大霧霾的一些事實(shí)(其中的照片引人入勝;這對于那些認(rèn)為環(huán)境問題歷史甚短的人無疑是當(dāng)頭棒喝)。這些學(xué)生提供了1952年倫敦空氣污染水平的一批數(shù)字，我把它們與北京的'最近數(shù)字做了比較。
Beijing’s poor airquality – 300 or somicrograms of particulate matter per cubic metre – has generated volumesof purple prose, but London’s numbers in the 1950s were consistently above 400, and surged to 1,600 during theGreat Smog – more than five times Beijing’s inearly August.
北京上空每立方米空氣約含300微克粉塵物質(zhì)，這一惡劣的空氣質(zhì)量已經(jīng)讓人寫出了許多華麗的抱怨文章，但倫敦在1950年代的這一數(shù)字持續(xù)超過400，并在大霧霾期間狂漲到1600，這是北京八月初數(shù)字的5倍以上。
